Proton conducting SOFCs (P-SOFCs) demonstrate advantages over oxygen-ion conducting SOFCs, such as less activation energies on ionic transport and higher fuel utilization efficiency. Central to the devices is a suitable cathode with high catalytic activity. Herein, a cubic perovskite BaCo0.7Fe0.22Sc0.08O3−δ(BCFSc) has been applied as the cathode in proton-conducting solid state fuel cell (SOFC) with BaZr0.1Ce0.7Y0.2O3−δ(BZCY) electrolyte. Peak power densities of 760, 591, 452 and 318 mW cm−2are obtained at 650, 600, 550 and 500 °C with humidified hydrogen as the fuel and air as the oxidant. A low polarization resistance of 0.05 Ω cm2under open circuit at 650 °C is observed.
