Deliverables
Lead by CNRS-LRP. Rheological analysis for developed electrolytes under different processing conditions, in particular flow-rates and temperature will be realized by LRP-ESR1.
See title.
Component based models and ex-situ analysis data of organic RFBs will be coupled with non-equilibrium thermodynamics by ZHA. Developed model will be validated by partners from WP3.
JM-ESR1 will test the GDEs as cathodes in a three-electrode setup battery and as both cathode and anode (bifunctional air electrode) in a two-electrode setup.
Lead by CNRS-LEPMI. LEP-ESR1 will develop and characterize a suitable membrane with cation or anion grafted on the hydrophilic chains.
DEN-ESR1 will synthesize electro-catalysts for oxygen reduction only and for oxygen reduction and evolution (bifunctional catalyst) to be integrated into innovative architecture of gas diffusion electrodes (GDE).
A prototype cell, equipped with gaskets from UOS-ESR1 and the membrane from LEP-ESR1, will be developed by JEN-ESR1 with conventional and rapid prototyping techniques.
The models which are developed at component and cell level will be used in WP1 for system design. The validation will be conducted through system analysis.
The detramental effects of ZnO dentrites to the performance of RFB will be avoided by investigating the effect of the addition of inorganic additives (i.e. CaO or MgO), polymers as well as surfactants.
Bromine crossover will be analysed in the anode exhaust where bromine ions will be measured with spectroscopic techniques. The segmented cell which is developed at ICT for vanadium based RFBs will be implemented to hydrogen bromine system in order to anaylse the current distrubitoon across the electrode.
Lead by CNRS-LRP. Zinc slurries will be developed with high colloidal stability and high discharge properties. Parameters such as zinc powder, additives and the carbonate amount will be optimized by ICT-ESR2.
A total of 30 publications are expected by month 48 (see D6.4). This deliverable will provide an earlier indication of the project's progress.
