To develop efficient cathode materials for solid oxide fuel cells (SOFCs) based on Ba (Zr 0.1 Ce 0.7 Y 0.2 )O 3Àd (BZCY) electrolyte, we have examined a series of cobalt-doped BZCY samples with the intended composition of BaZr 0.1 Ce 0.7 Y 0.2Àx Co x O 3Àd (where x ¼ 0, 0.02, 0.05, 0.075, 0.1, 0.2).
BaZr 0.1 Ce 0.7 Y 0.1 Yb 0.1 O 3-ı (BZCYYb) exhibits adequate protonic conductivity as well as sufficient chemical and thermal stability over a wide range of SOFC operating conditions, while layered perovskite PrBaCo 2 O 5+ı (PBCO) has advanced electrochemical properties. This research fully takes a
