Abstract

A cobalt-free perovskite oxide, Ba_0.5Sr_0.5Zn _0.2Fe_0.8O_3-δ (BSZF), was investigated as a novel cathode material for intermediate-temperature solid-oxide fuel cells (IT-SOFCs). Room-temperature nonstoichiometry of BSZF was as high as 0.412, which was favorable for oxygen-reduction reaction. At 700°C, the polarization resistances were as low as 0.22 and 0.13 Ω·cm ², respectively, for pure and impregnated BSZF cathodes under open-circuit conditions, suggesting that oxygen-deficient BSZF was a promising cathode candidate for IT-SOFCs.
