Abstract
En 中文
Solid oxide fuel cell (SOFC) uses solid oxide as an electrolyte and has a high-power generation efficiency. One of the major problems in the development of SOFC is the side reaction that occurs at the interface between the electrode and the electrolyte. (Y, Ca)CoO3-delta(3) materials were evaluated as a new air electrode material to replace the conventional (La, Sr)CoO3 materials. Y0.8Ca0.1CoO3-delta has good compatibility with Y-stabilized ZrO2 (YSZ) electrolyte. In addition, the power generation performance was equal to or better than the conventional SOFC cells.
