Abstract

The SrCo_0.9Sb_0.1O_3-d (SCS) composite oxide with cubic perovskite structure was synthesized by a modified Pechini method and examined as a novel cathode for protonic ceramic membrane fuel cells (PCMFCs). At 700 °C and under open-circuit condition, symmetrical SCS cathode on BaZr_0.1Ce_0.7Y_0.2O_3-d (BZCY7) electrolyte showed low polarization resistances (R_p) of 0.22 Ocm² in air. A laboratory-sized tri-layer cell of NiO-BZCY7/BZCY7/SCS was operated from 500 to 700 °C with humidified hydrogen (~3% H₂O) as fuel and the static air as oxidant. A high open-circuit potential of 1.004 V, a maximum power density of 259 mW cm^-2, and a low polarization resistance of the electrodes of 0.14 Ocm² was achieved at 700 °C. © 2008 Elsevier B.V.
