Abstract
Solid oxide fuel cells (SOFCs) have received a lot of attention as promising electrochemical power generation devices due to their high electrical efficiency and adaptability to a variety of fuels such as hydrocarbons, ammonia, and hydrogen. The utilization of LaSrTiFeO3-δperovskite oxide was proposed as an oxygen permeable membrane and electrode materials of SOFCs. Durability in thermal cycling test is an important factor for applying SOFCs to power sources. The reduction of operating temperature and enhancement of thermal-cycling capability are indispensable requirement for industrial-scale commercialization of SOFCs. A new cathode material for SOFCs has been developed in R&D Center of Noritake Co., Ltd. In which, it contain La0.6Sr0.4TixFe1-xO3-δ (0<x<0.4) and La0.6Sr0.4CoyFe1-yO3-δ (0<y<1). Here, we report the performance evaluation of our developed cathode material. It was found that the developed cathode material had a high power density and extremely high stability to hydrogen and ammonia fuel.
