Fuel cell systems supplied with ammonia have been developed as the SIP Project in Japan. Solid oxide fuel cells (SOFCs) from single cells to stacked-level cells coupled with an ammonia cracking catalytic reactions have been fabricated to evaluate their fuel flexibility, generation efficiency, components, and degradation factors. Active ammonia cracking and auto-thermal cracking catalysts have been developed using base metal components. Starting with research on cell components and single cells, stack scale examinations have been extended up to 1-kW-class cells. Generation testing of hot modules and packaged SOFC systems has been performed for verification testing. Anion exchange membrane fuel cell (AEMFC) stacks were operated by supplying fuel after ammonia cracking.
