摘　　要：固体氧化物燃料电池是目前最成熟、最有发展潜力的燃料电池,具有广泛的应用前景。文章综述了该电池阴极材料La1-xSrxMnO3的制备方法,比较了各种制备方法的优缺点,介绍了一种新型的制备方法—自蔓延高温合成法的研究进展。指出:自蔓延高温合成法能显著缩短阴极材料的制备周期和减少能耗,从而能降低其制造成本、促进其实用化和产业化。Solid oxide fuel cell(SOFC) is one of the research focus and it is supposed a wide application and further development.In the present paper,some preparation methods such as solid state reaction,thermolytic dissociation of drop,Sol-gel,low temperature combustion and electrochemical deposition methods are comprehensively introduced and compared for preparing La_(1-x)Sr_xMnO_3 used as cathode materials of SOFC.The advantage and disadvantage of each method are analysed.Self-propagation high temperature synthesis(SHS),which is time saving and low cost,is emphasized as a new method to prepare La_(1-x)Sr_xMnO_3.And it is pointed out that preparing La_(1-x)Sr_xMnO_3 by SHS is of great practical and theoretical value and it benefits the application and industrialization of SOFC.
