In this study, the oxygen reduction reaction (ORR) properties of Co-free perovskite-type Ba 0.5 Sr 0.5 Fe 0.91 Al 0.09 O 3-δ (BSFAl009), and Ba 0.5 Sr 0.5 Fe 0.8 Cu 0.2 O 3-δ (BSFCu) were investigated with proton conducting Ba 0.5 Sr 0.5 Ce 0.6 Zr 0.2 Gd 0.1 Y 0.1 O 3-δ (BSCZGY) and oxide ion conducting La 0.8 Sr 0.2 Ga 0.8 Mg 0.2 O 3-δ (LSGM) electrolytes. BSFAl009 and BSFCu were synthesized through sol-gel method. BSFCu-LSGM/LSGM/BSFCu-LSGM symmetrical cell showed the lowest area specific resistance (ASR) of 0.08 Ωcm 2 in air at 800°C, while BSFCu-BSCZGY/BSCZGY/BSFCu-BSCZGY symmetrical cell showed slightly lower performance (0.25 Ωcm 2 ) under the same condition. To further understand the oxygen consumption and release properties in these oxides, thermogravimetric analysis was also performed in air/N 2 .
