Abstract

Anode supported NiO-BZCY/BZCY/SFNb cell was fabricated and the performance was investigated. A peak power density of 538 mW cm−2and a low polarization resistance of 0.23 Ω cm2were 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.
