Final Report Summary - QUASIDRY (Quasi-anhydrous and dry membranes for next generation fuel cells)
Executive Summary:
The primary objective of QuasiDry was the development of selected highly innovative approaches to polymer and membrane design to open up the possibility for fuel cells to operate at temperatures of around 120 °C, a desirable, yet currently impractical operating point with currently available materials. The QuasiDry partnership of six technical partners provided a balance between industry and academia that pooled its complementary skills and competences. The partnership was structured to cover the range of expertise required to carry the project through and achieve its objectives, for full exploitation and use of the results, and for professional project management and dissemination of project results.
The work plan comprised work packages dedicated to the main developmental RTD activities on polymers and membranes (WP2), catalyst development (WP3), and validation of the project materials in membrane electrode assemblies (MEAs, WP4). The focus of WP1 was the development of protocols for functional materials characterisation and evaluation of MEAs under project-specific conditions. WP5 and WP6 were dedicated to dissemination and use of results, and to project management, respectively.
WP2 targeted the development of new concepts for fuel cell electrolyte membranes. Its ambition with regard to conductivity values was considerable. Proton conducting materials, polymers and membranes (i) functionalised only with phosphonic acid groups (ii) incorporating polymer-bound sulfonic and phosphonic acid functionalities (iii) cross-linked high acid doping level membranes and (iv) mixed functionality membranes incorporating phosphonic and phosphoric acids, have been developed and their properties characterised, and transferred to WP4. Key outcome includes the novel properties offered by mixed functionality (sulfonic-phosphonic, and phosphoric-phosphonic), distinct from those observed for the separate components alone. Target conductivities have been achieved with two of the above membrane classes. Overall, the boundaries in the field of novel approaches to proton conducting membranes have been expanded and some very promising results achieved with significant progress over the state of the art.
In WP3, new ternary alloy catalysts for cathodes (PtXY) demonstrated improved kinetic mass activity (while retaining high stability) for operation at high temperatures from 120-180 °C and was successfully scaled-up to 200 g for further MEA development studies. A composite Pd-Pt catalyst with ultra-low Pt content produced a synergistic effect and showed a much larger activation effect for the Pd-based catalyst than a conventional Pt-alloy. This makes such composite Pd system quite appealing for application under automotive conditions characterised by intermediate temperature and low relative humidity operation. The use of heteropolyoxometalate promoters further increased the catalytic activity of a Pd catalyst under automotive conditions. Alternative non-carbon catalyst supports with specific architectures have been developed that show high electrochemical corrosion resistance.
A wide range of innovative materials from WP2 and WP3 were evaluated in WP4 using both in situ and ex situ techniques. Three new catalysts, four novel classes of membranes and the compatibiliser concept were all investigated under a wide range of conditions and constructions. Several of these new materials show significant improvements and potential compared to the initial benchmark materials. At the low RH, 120 °C, ambient pressure target conditions of the project, peak power densities >0.4 W/cm2 were achieved at useable cell voltages with the cross-linked acid doped membranes, more than doubling the initial benchmark material’s performance. Target power density could also be achieved by raising both humidification and pressure using mixed functionality sulfonic –phosphonic functionalised membrane materials. Durability was validated with one of the new catalysts and one of the new membranes demonstrating durability on par with the benchmark material. Overall some very promising practical results have been achieved from the new membrane classes, which demonstrate that significant progress has been made over the three years of the project and reveals their obvious potential.
Project results have been disseminated in conferences (25 presentations) and journal publications (9 articles).
Project Context and Objectives:
Fuel cells using oxides or polymers hold great promise in the future diversification of energy supply for applications ranging from the portable electronics market, through automotive use and stationary power generation to other niche areas related to the leisure market or military purposes. Real impact of the potential in terms of reduced emissions and alternative fuels allowed by fuel cell technology awaits introduction of a mass market application, and it is considered that the greatest bearing in this arena will be brought by fuel-cell electric vehicles.
In recent years, a vast number of polymers have been proposed and evaluated as possible materials for proton exchange membrane fuel cells (PEMFC), in particular for automotive application. Sulfonic acid functionalised perfluorinated polymers are a class of benchmark materials having excellent proton conductivity, mechanical and chemical stability. Nafion®, the 3M and Aquivion® membranes are representative perfluorosulfonic acid (PFSA) ionomers. Despite the wide use of Nafion® and other state of the art PFSAs, their maximum performance in a fuel cell is at moderate operation temperatures (80 °C). This falls significantly short of the automotive industry long-term targets, which is for a cell temperature of 120 – 130 °C, with no humidification of reactant hydrogen and air, since humidification increases systems complexity and costs. It is agreed by the automotive industry that the too low temperature of operation and the need for humidification of current polymer exchange membrane fuel cell membranes is an obstacle to widespread implementation of fuel cell vehicles (FCV). High temperature of operation is required to enable the heat generated by the fuel cell stack to be exchanged efficiently.
In the above PFSA membranes, the proton is transferred by water molecules. Over the last decade, new concepts have evolved engaging alternative proton carriers that mark a move towards reducing the need for high levels of hydration of the fuel cell membrane. The ideal protogenic group in a "quasi-anhydrous" membrane environment should be amphoteric, exhibit proton donor and acceptor properties and show a high degree of self-dissociation. It also should have a high dielectric constant to enhance the charge separation and be stable under fuel cell operation conditions. Candidate "solvents" alternative to water include nitrogen heterocycles and phosphonic acids. While initial results effectively showed that such solvents could be immobilised on to polymer backbones, the low concentration of functional groups in this first work led to rather low proton conductivity values.
The objective of QuasiDry was to develop the fuel cell electrolyte membranes of the next generation of fuel cells, satisfying the long-term automotive targets. The increase of proton conductivity with temperature, including at low RH, will allow continuous increase in fuel cell performance with temperature, rather than the drop in performance for all sulfonic acid functionalised membranes above ca. 80-90 °C. QuasiDry membranes were evaluated by electrode and MEA development, to the scale of small-scale (50 cm2) single cell demonstrators. The end result has been a step-change in the properties of these materials, as is required to underpin the future of European fuel cell research.
Several approaches to automotive fuel cell membranes were screened within the framework of Framework 6 Integrated Project Autobrane (completed 31st October 2009), including advanced perfluorosulfonic acid (PFSA) type membranes, and their composites containing an inorganic component, novel hydrocarbon type polymers with sulfonic acid functions, consideration of some novel polymers with protogenic functions other than sulfonic acid, as well as novel processing routes. Using a state-of-the-art PFSA membrane, Autobrane achieved its goal of fuel cell stack operation to 120 °C, although performance dropped severely as the temperature was increased, anode and cathode gases were hydrated, and some over-pressure was applied.
It was the intention of QuasiDry to build on some of the achievements of Autobrane by concentrating efforts on some of the most promising long-term options developed in its framework. The materials selected were those functionalised with phosphonic acid groups, since we have shown that phosphonic acid containing polymeric materials have the possibility of operating at higher temperature at low humidity conditions. Their properties are in clear contrast to those of any PFSA, or any sulfonic acid containing polymer.
The project covered the following topics:
1. Development of innovative polyphosphonic acid functionalised polymers and materials and membranes from them, phosphoric acid doped membranes and mixed functionality membranes, corresponding electrolyte dispersions, and characterisation of polymer and materials components, and membrane properties:
Despite considerable progress, in formulating and implementing new approaches leading to novel proton conducting membrane systems that have high proton conductivity at high temperature through the full range of relative humidity remains a most difficult challenge. Phosphoric and phosphonic acid derivatives in particular were considered suitable candidates as ionomers because of their efficient proton transport at high temperature that involves proton hopping via hydrogen bonds. Recent results on phosphonated polymeric membranes and their associations with sulfonic acid functionalised polymers have indicated that very high local concentrations of phosphonic acid, forming large hydrogen bonded aggregates, are needed in order to reach high proton conductivities. Innovative synthetic immobilisation strategies have to be developed to minimise local dilution effects and aggregation constraints of the acid units.
2. Design and development of supported electrocatalysts with high activity in the appropriate electrolyte environment:
Electrocatalyst development was required to accompany the above step-changes in high temperature, low RH properties of proton conducting membranes. Significant progress beyond the state of the art was expected by concentrating efforts in specific directions most relevant to QuasiDry objectives, including designed Pt-alloy catalyst compositions to overcome strong activation control at low current density, using stabilised carbon supports as well as non-carbon (oxide and carbide) supports to avoid high temperature corrosion, and reducing costs by developing Pt-free or ultra-low Pt loaded catalysts in conjunction with anchored heteropolyacid promoters to enhance reaction kinetics (oxygen diffusion coefficient, oxygen solubility, proton transfer at the electrode-electrolyte interface).
3. Development of electrodes and MEAs adapted for the novel polymer membranes and characterisation of the MEAs in single cells:
An MEA having an appropriate electrode structure and membrane-electrode interface was required to translate the potential of the novel membranes to proven MEA performance in a fuel cell, and thus there was a major effort on the development of appropriate electrode structures. Electrode development itself, has studied the impact of key structural and compositional variables, including electrode thickness, pore volume, pore size distribution, hydrophobicity, catalyst loading requirement, and level of ionomer incorporation. This electrode development study went hand-in-hand with developing the processes by which the catalyst layer is formulated and applied. A fundamental study of the interface involved studying the effectiveness of materials capable of electron transfer to the electrode and proton transport to the membrane (mixed ionic-electronic conductors.
The final target of QuasiDry was to achieve the development of membrane materials having conductivity at 120 °C and <25% RH of >50 mS/cm, in the range 50-100 mS/cm, and which have low dependence of conductivity on RH and also temperature ( The project provided the opportunity to vastly add value to some exciting new results consistently showing the promise of phosphonic acid functionalised polymeric membrane systems and maintain the lead of European researchers in this field. To carry the project through to its conclusion, a consortium of world-leading polymer and materials chemists was assembled, experienced in the field of materials developments for fuel cells. Participation by Johnson Matthey Fuel Cells Ltd and FuMA-Tech GmbH showed the credibility and the potential of the proposed research, and guaranteed the future high impact of the research results.

The primary objective of QuasiDry was the development of selected highly innovative approaches to polymer and membrane design to open up the possibility for fuel cells to operate at temperatures of around 120 °C, a desirable, yet currently impractical operating point with currently available materials. The QuasiDry partnership of six technical partners provided a balance between industry and academia that pooled its complementary skills and competences. The partnership was structured to cover the range of expertise required to carry the project through and achieve its objectives, for full exploitation and use of the results, and for professional project management and dissemination of project results.
The work plan comprised work packages dedicated to the main developmental RTD activities on polymers and membranes (WP2), catalyst development (WP3), and validation of the project materials in membrane electrode assemblies (MEAs, WP4). The focus of WP1 was the development of protocols for functional materials characterisation and evaluation of MEAs under project-specific conditions. WP5 and WP6 were dedicated to dissemination and use of results, and to project management, respectively.
WP2 targeted the development of new concepts for fuel cell electrolyte membranes. Its ambition with regard to conductivity values was considerable. Proton conducting materials, polymers and membranes (i) functionalised only with phosphonic acid groups (ii) incorporating polymer-bound sulfonic and phosphonic acid functionalities (iii) cross-linked high acid doping level membranes and (iv) mixed functionality membranes incorporating phosphonic and phosphoric acids, have been developed and their properties characterised, and transferred to WP4. Key outcome includes the novel properties offered by mixed functionality (sulfonic-phosphonic, and phosphoric-phosphonic), distinct from those observed for the separate components alone. Target conductivities have been achieved with two of the above membrane classes. Overall, the boundaries in the field of novel approaches to proton conducting membranes have been expanded and some very promising results achieved with significant progress over the state of the art.
In WP3, new ternary alloy catalysts for cathodes (PtXY) demonstrated improved kinetic mass activity (while retaining high stability) for operation at high temperatures from 120-180 °C and was successfully scaled-up to 200 g for further MEA development studies. A composite Pd-Pt catalyst with ultra-low Pt content produced a synergistic effect and showed a much larger activation effect for the Pd-based catalyst than a conventional Pt-alloy. This makes such composite Pd system quite appealing for application under automotive conditions characterised by intermediate temperature and low relative humidity operation. The use of heteropolyoxometalate promoters further increased the catalytic activity of a Pd catalyst under automotive conditions. Alternative non-carbon catalyst supports with specific architectures have been developed that show high electrochemical corrosion resistance.
A wide range of innovative materials from WP2 and WP3 were evaluated in WP4 using both in situ and ex situ techniques. Three new catalysts, four novel classes of membranes and the compatibiliser concept were all investigated under a wide range of conditions and constructions. Several of these new materials show significant improvements and potential compared to the initial benchmark materials. At the low RH, 120 °C, ambient pressure target conditions of the project, peak power densities >0.4 W/cm2 were achieved at useable cell voltages with the cross-linked acid doped membranes, more than doubling the initial benchmark material’s performance. Target power density could also be achieved by raising both humidification and pressure using mixed functionality sulfonic –phosphonic functionalised membrane materials. Durability was validated with one of the new catalysts and one of the new membranes demonstrating durability on par with the benchmark material. Overall some very promising practical results have been achieved from the new membrane classes, which demonstrate that significant progress has been made over the three years of the project and reveals their obvious potential.
Project results have been disseminated in conferences (25 presentations) and journal publications (9 articles).
Project Context and Objectives:
Fuel cells using oxides or polymers hold great promise in the future diversification of energy supply for applications ranging from the portable electronics market, through automotive use and stationary power generation to other niche areas related to the leisure market or military purposes. Real impact of the potential in terms of reduced emissions and alternative fuels allowed by fuel cell technology awaits introduction of a mass market application, and it is considered that the greatest bearing in this arena will be brought by fuel-cell electric vehicles.
In recent years, a vast number of polymers have been proposed and evaluated as possible materials for proton exchange membrane fuel cells (PEMFC), in particular for automotive application. Sulfonic acid functionalised perfluorinated polymers are a class of benchmark materials having excellent proton conductivity, mechanical and chemical stability. Nafion®, the 3M and Aquivion® membranes are representative perfluorosulfonic acid (PFSA) ionomers. Despite the wide use of Nafion® and other state of the art PFSAs, their maximum performance in a fuel cell is at moderate operation temperatures (80 °C). This falls significantly short of the automotive industry long-term targets, which is for a cell temperature of 120 – 130 °C, with no humidification of reactant hydrogen and air, since humidification increases systems complexity and costs. It is agreed by the automotive industry that the too low temperature of operation and the need for humidification of current polymer exchange membrane fuel cell membranes is an obstacle to widespread implementation of fuel cell vehicles (FCV). High temperature of operation is required to enable the heat generated by the fuel cell stack to be exchanged efficiently.
In the above PFSA membranes, the proton is transferred by water molecules. Over the last decade, new concepts have evolved engaging alternative proton carriers that mark a move towards reducing the need for high levels of hydration of the fuel cell membrane. The ideal protogenic group in a "quasi-anhydrous" membrane environment should be amphoteric, exhibit proton donor and acceptor properties and show a high degree of self-dissociation. It also should have a high dielectric constant to enhance the charge separation and be stable under fuel cell operation conditions. Candidate "solvents" alternative to water include nitrogen heterocycles and phosphonic acids. While initial results effectively showed that such solvents could be immobilised on to polymer backbones, the low concentration of functional groups in this first work led to rather low proton conductivity values.
The objective of QuasiDry was to develop the fuel cell electrolyte membranes of the next generation of fuel cells, satisfying the long-term automotive targets. The increase of proton conductivity with temperature, including at low RH, will allow continuous increase in fuel cell performance with temperature, rather than the drop in performance for all sulfonic acid functionalised membranes above ca. 80-90 °C. QuasiDry membranes were evaluated by electrode and MEA development, to the scale of small-scale (50 cm2) single cell demonstrators. The end result has been a step-change in the properties of these materials, as is required to underpin the future of European fuel cell research.
Several approaches to automotive fuel cell membranes were screened within the framework of Framework 6 Integrated Project Autobrane (completed 31st October 2009), including advanced perfluorosulfonic acid (PFSA) type membranes, and their composites containing an inorganic component, novel hydrocarbon type polymers with sulfonic acid functions, consideration of some novel polymers with protogenic functions other than sulfonic acid, as well as novel processing routes. Using a state-of-the-art PFSA membrane, Autobrane achieved its goal of fuel cell stack operation to 120 °C, although performance dropped severely as the temperature was increased, anode and cathode gases were hydrated, and some over-pressure was applied.
It was the intention of QuasiDry to build on some of the achievements of Autobrane by concentrating efforts on some of the most promising long-term options developed in its framework. The materials selected were those functionalised with phosphonic acid groups, since we have shown that phosphonic acid containing polymeric materials have the possibility of operating at higher temperature at low humidity conditions. Their properties are in clear contrast to those of any PFSA, or any sulfonic acid containing polymer.
The project covered the following topics:
1. Development of innovative polyphosphonic acid functionalised polymers and materials and membranes from them, phosphoric acid doped membranes and mixed functionality membranes, corresponding electrolyte dispersions, and characterisation of polymer and materials components, and membrane properties:
Despite considerable progress, in formulating and implementing new approaches leading to novel proton conducting membrane systems that have high proton conductivity at high temperature through the full range of relative humidity remains a most difficult challenge. Phosphoric and phosphonic acid derivatives in particular were considered suitable candidates as ionomers because of their efficient proton transport at high temperature that involves proton hopping via hydrogen bonds. Recent results on phosphonated polymeric membranes and their associations with sulfonic acid functionalised polymers have indicated that very high local concentrations of phosphonic acid, forming large hydrogen bonded aggregates, are needed in order to reach high proton conductivities. Innovative synthetic immobilisation strategies have to be developed to minimise local dilution effects and aggregation constraints of the acid units.
2. Design and development of supported electrocatalysts with high activity in the appropriate electrolyte environment:
Electrocatalyst development was required to accompany the above step-changes in high temperature, low RH properties of proton conducting membranes. Significant progress beyond the state of the art was expected by concentrating efforts in specific directions most relevant to QuasiDry objectives, including designed Pt-alloy catalyst compositions to overcome strong activation control at low current density, using stabilised carbon supports as well as non-carbon (oxide and carbide) supports to avoid high temperature corrosion, and reducing costs by developing Pt-free or ultra-low Pt loaded catalysts in conjunction with anchored heteropolyacid promoters to enhance reaction kinetics (oxygen diffusion coefficient, oxygen solubility, proton transfer at the electrode-electrolyte interface).
3. Development of electrodes and MEAs adapted for the novel polymer membranes and characterisation of the MEAs in single cells:
An MEA having an appropriate electrode structure and membrane-electrode interface was required to translate the potential of the novel membranes to proven MEA performance in a fuel cell, and thus there was a major effort on the development of appropriate electrode structures. Electrode development itself, has studied the impact of key structural and compositional variables, including electrode thickness, pore volume, pore size distribution, hydrophobicity, catalyst loading requirement, and level of ionomer incorporation. This electrode development study went hand-in-hand with developing the processes by which the catalyst layer is formulated and applied. A fundamental study of the interface involved studying the effectiveness of materials capable of electron transfer to the electrode and proton transport to the membrane (mixed ionic-electronic conductors.
The final target of QuasiDry was to achieve the development of membrane materials having conductivity at 120 °C and <25% RH of >50 mS/cm, in the range 50-100 mS/cm, and which have low dependence of conductivity on RH and also temperature (
