摘　　要：近年来,由于具有极高的理论转化效率,液态金属阳极直接碳固体氧化物燃料电池受到关注;然而,液态金属电极对电解质的腐蚀是降低其性能和限制其寿命的关键因素之一。本文综述了液态金属和氧化物,主要是液态锑(Sb)和氧化锑(Sb_(2)O_(3)),对固体氧化物燃料电池常用ZrO_(2)和CeO_(2)基电解质的化学和电化学腐蚀研究成果,并讨论了减缓腐蚀程度的途径与可能性。Liquid metal anode direct carbon solid oxide fuel cells have attracted recent attention due to the extremely high theoretical conversion efficiency. However, the corrosion of liquid metal electrodes to electrolytes is one of the key factors to degrade their performance and limit their life. This review represented the results on the chemical and electrochemical corrosion of liquid metal and oxides, i.e., mainly liquid antimony(Sb) and antimony oxide(Sb_(2)O_(3)), to the most frequently used ZrO_(2) and CeO_(2) based electrolytes in solid oxide fuel cells. The possible methods of reducing the degree of corrosion were discussed.
