Many researchers have studied on perovskite oxide for its unique structure.Perovskite oxides,ABO_(3-δ),with different A and B metals have shown wide applications in many fields,in particular solid oxide electrolysers.SrFeO_(3-δ),typical perovskite oxides,in which iron is the mixed-valence cation with the capacity to change the chemical valence,have a wide range of oxygen nonstoichiometry.In this study,Sr_(0.9)Fe_(0.9)Zr_(0.1)O_(3-δ)(SFZO) is synthesized and then treated in 5%H_2/Ar and air at high temperature,exhibiting excellent redox stability.Redox-stable structure,oxygen vacancy and electrical properties of SFZO are investigated.Steam electrolysis is then performed with SFZO cathode under 5%H_2O/5%H_2/Ar and 5%H_2O/Ar atmospheres,respectively.The present results indicate that the SFZO is a novel promising cathode material for solid oxide steam electrolyser. 相似文献
