MMLRC=SOFC Report Summary

Funded under: FP7-JTI

Periodic Report Summary 3 - MMLRC=SOFC (Working towards Mass Manufactured, Low Cost and Robust SOFC stacks)

Project Context and Objectives:
SOFC stacks are currently being developed for automotive applications such as APU, for portable devices and possibly in the near future also vehicle propulsion. They supply electrical efficiencies of up to 60% with hydrogen and methane fuel. Due to the requirements of mobile and portable applications only lightweight SOFC stacks with low weight and short start-up times will be employed for these markets.
Start-up times for vehicles of most kinds (road and rail vehicles, even aircraft and ships) are short compared to those for power generation. The same applies to portable devices which are expected to be operational within very short time intervals. The requirements for thermal cycling in lightweight stacks are therefore high. For stationary applications rapid start-up will also be an advantage since the SOFC system can be operated in accordance with the electrical and thermal loads of the customer. Lightweight SOFC stacks therefore need to display excellent thermo-mechanical properties to allow both rapid start-up and thermal cycling without degradation of sealings and contacts.
High quality standards in manufacturing are necessary in order to minimise production tolerances and ensure the required robustness of the lightweight SOFC stacks. As many automated precision assembly processes as possible have to be implemented in an approach of parallel improvement of quality and lowering of manufacturing cost.
The MMLCR=SOFC project addresses a design solution that uses thin sheet metal to decrease cost and weight of materials. The design allows for low-cost mass manufacturing of stack components, and automated quality assurance and assembly.

Project Results:
During the third reporting period the stack Design 2.0 was ‘frozen’ in late 2013, and BORIT started to manufacture samples that were built into cassettes at JUELICH and will subsequently be tested in the last project period.
Glass samples were further characterised thermo-mechanically. The laser supported glass welding, as an important element of automated manufacturing, was further refined and developed in view of the pending milestone in 2013.
The automated manufacturing line development was concluded at its first stage and is now pending input from the finalised design in the second half of 2014.
Following the mid-term review in March 2014, the suggestion by the reviewers to extend the project by one year in order to allow for more time to test the D2.0 stacks was accepted by the FCH JU and the consortium, and 12 months added to the project duration. MMLCR=SOFC will now end in June 2015.

Potential Impact:
The project objectives are:
1. to further develop and qualify the JÜLICH lightweight SOFC stack with respect to design, sealing materials and protective coatings;
2. developing industrial mass manufacturing processes and automated equipment for repeating unit manufacturing, including low-cost produced cells
3. setting up automated industrial mass manufacturing processes and equipment for stack assembly and joining
4. performing tests under relevant application operating conditions for steady state and transient operation
5. verifying the industrialisability and market relevance of the project results with the perspective of adequate valorisation after project termination
6. evaluating the environmental impact of the SOFC stack product and identifying any materials supply bottlenecks
The industry project partners are all in a position to commercialise the project results following the successful qualification and testing of the stacks.
