Fuel cells directly convert chemical energy contained in fuels into electric energy, thus generation efficiency and reduced harmful gas emissions.
Among fuel cells, the solid oxide fuel cell (SOFC) offers the highest power generation efficiency and is expected to play a leading role in dispersed power generation. Because the SOFC generally operates at a temperature close to 1000 , it can utilize only a limited number of materials, and its high cost remains a problem. To overcome such obstacles, we have focused on "intermediate-temperature operation" below 800, while tacking SOFC-related issues from numerous angles, from the development of materials for cell components to new systems.
