中文摘要：
固体氧化物燃料电池（SOFCs）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对燃料气较好的催化活性及超强抗积碳能力而越来越被广泛地应用于直接烃类SOFCs的阳极材料中。本文对钙钛矿型固体氧化物燃料电池阳极材料的最新研究进展进行了较为全面的综述,从阳极的设计要求出发,着重比较了LaCrO3系列、SrTiO3系列和双钙钛矿等阳极材料的稳定性、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。
英文摘要：
Solid-oxide fuel cells （SOFCs） 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 anode materials for SOFCs because of their high mixed ionic-electronic conductivity （MIEC）, favorable catalytic activity for fuel oxidation, and super-carbon coking resistance. The recent progress on the perovskite-based anode materials for SOFCs is reviewed. In order to find a way to satisfy the strict requirements of anode with hydrocarbon fuels, this article is focused on their phase stability, electronic and/or ionic conductivity, and catalytic activity for fuel oxidation. The main problems of current perovskite-based anodes for practical application are pointed out and the possible future research directions are proposed.
