CERAMIC MATERIAL, OXYGEN ELECTRODE MATERIAL, OXYGEN ELECTRODE, AND FUEL CELL AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an oxygen electrode for a fuel cell having the equivalent level of durability as that of LSM or PSM and exhibiting high conductivity and high electrode activity (low polarization resistance) even at a temperature around 800°C.

SOLUTION: The oxygen electrode for a fuel cell is prepared by sintering an oxygen electrode material containing a ceramic material expressed by the following formula: Pr(1-x)SrxCo(1-y)FeyO3, where 0.1≤x≤0.5 and 0.1≤y≤0.9.
