摘要 固体氧化物燃料电池(SOFC_s)作为一种高效、洁净的化学电源已经受到各国的重视。钙钛矿型复合氧化物由于其较高的混合导电性和较好的催化活性而被越来越广泛地应用于SOFCs的阴极材料中。对钙钛矿型中低温固体氧化物燃料电池阴极材料的最新研究进展进行了较为全面的综述,从阴极的设计要求出发,着重比较了A_(1-x)Sr_xCoO_3(A=La,Sm,Dy等稀土元素)系列、A_(1-x)Sr_xCo_(1-y)FeyO_(3-δ)、SrSc_xCo_(1-x)O_(3-δ)系列和双钙钛矿系列阴极材料的稳定性、电导率以及电催化活性,指出了其不足,并对其应用前景进行了展望。 Solid-oxide fuel cells(SOFC_s) have attracted considerable attentions due to their high energy conversion efficiency,high power density and extremely low pollution.Perovskite-based materials have been widely used as cathode materials for SOFCs because of their high mixed ionic-electronic conductivity(MIEC) and favorable catalytic activity.The recent progress on the perovskite-based cathode materials for intermediate-to-low temperature SOFCs was reviewed.In order to find a way to satisfy the strict requirements of cathode,the phase stability,electronic and/or ionic conductivity,and catalytic activity of A_(1-x)Sr_xCoO_3,A_(1-x)Sr_xCo_(1-y)FeyO_(3-δ),SrSc_xCo_(1-x)O_(3-δ) and double perovskite materials were focused.The main problems of current perovskite-based cathodes for practical application are pointed out and the possible future research directions are proposed.
