摘　　要：固体氧化物燃料电池(SOFC)的低温化已成为SOFC商业化发展的必然趋势。目前,SOFC低温化的主要策略是通过制备电解质薄膜以降低电解质的厚度和研发新型电解质材料以提高电解质的离子电导率。本文简述了SOFC的工作原理,从电解质薄膜的制备技术及新型电解质材料的应用两个方面对SOFC低温化的研究进展进行了论述,探讨了干压法、流延法、沉积法及等离子喷涂法等技术的优劣之处,对比分析了锆基电解质材料、铈基电解质材料、铋基电解质材料及质子导体基电解质材料在中低温区间(400~700℃)的离子电导率,并指出了在SOFC商业化进程中亟待解决的问题。The low-temperature development of solid oxide fuel cells(SOFC)has become an inevitable trend in the commercialization of SOFC.Currently,the main strategies for intermediate-low temperature SOFC are to reduce the thickness of the electrolyte by preparing electrolyte films and to improve the ionic conductivity of the electrolyte by developing new electrolyte materials.This article describes the working principle of SOFC,and discusses the research progress in intermediate-low temperature SOFC from two aspects:the preparation technology of electrolyte thin films and the application of new electrolyte materials.In terms of the preparation technology of electrolyte thin films,the advantages and disadvantages of dry pressing,tape casting,deposition,and plasma spraying methods were discussed.In terms of the application of new electrolyte materials,the ionic conductivity of zirconium based electrolyte materials,cerium based electrolyte materials,bismuth based electrolyte materials,and proton conductor based electrolyte materials in the medium and low temperature range(400~700℃)was compared and analyzed.Finally,the urgent problems to be solved in the commercialization process of SOFC are pointed out.
