Stabilization of high-cobalt-content perovskites for use as cathodes in solid oxide fuel cells

B-site modification of the high-cobalt-content perovskite Ba sub(0.5)Sr sub(0.5)Co sub(0.8)Fe sub(0.2)O sub(3-) delta reduces its thermal expansion coefficient and stabilizes its structure, allowing its long-term operation without degradation of the area-specific resistance, and thus, maintaining th...

Zusammenfassung:B-site modification of the high-cobalt-content perovskite Ba sub(0.5)Sr sub(0.5)Co sub(0.8)Fe sub(0.2)O sub(3-) delta reduces its thermal expansion coefficient and stabilizes its structure, allowing its long-term operation without degradation of the area-specific resistance, and thus, maintaining the high electrode performance.
