Performance Degradation Analysis of Different Type SOFCs

Solid oxide fuel cells (SOFC) technology has been developed by many manufacturers and there are various types of stacks having different design and materials. CRIEPI started to make detailed analyses on cell/stack performance by changing gaseous compositions in anode and cathode to establish the representation scheme for six different types of SOFCs, which have been developed by MHPS, Kyocera, TOTO, NTK, NGK, and Murata under the new NEDO project from FY2013 to FY2017. In this study, we report our recent activities toward the durability improvement of SOFCs based on the electrode performance model.
