Abstract

A novel cobalt-free cubic perovskite SrFe_0.95Nb_0.05O_3−δ (SFNb) was synthesized and investigated as cathode for proton-conducting solid state fuel cell (H-SOFC) with BaZr_0.1Ce_0.7Y_0.2O_3−δ (BZCY) as the electrolyte. Anode supported NiO-BZCY/BZCY/SFNb cell was fabricated and the performance was investigated. A peak power density of 538 mW cm⁻² and a low polarization resistance of 0.23 Ω cm² were obtained at 650 °C with hydrogen as the fuel and air as the oxidant. No obvious cell degradation was observed during the 50 h test. All the results indicated that the cobalt-free SFNb oxide is a promising cathode material for H-SOFCs.
