摘要
8%(摩尔分数,如无特别说明,下同)氧化钇稳定的氧化锆(8YSZ)薄膜是固体氧化物燃料电池(SOFC)的核心部件,直接影响SOFC的输出性能。本文介绍了氧化锆电解质薄膜化工艺,详细地分析了烧结助剂、粘结剂体系以及浆料流变性对氧化锆浆料的影响,总结了流延速度、干燥环境等流延工艺参数对氧化锆流延生带厚度以及品质的作用,并对近年来氧化锆生带的先进烧结方式进行了阐述,讨论了电解质厚度及结构对氧化锆电解质薄膜致密度与离子电导率的影响,最后对流延成型工艺制备高品质的氧化锆薄膜的前景和方向进行了展望。
8 mol%yttria-stabilized zirconia(8YSZ)thin films are the core components of solid oxide fuel cells(SOFCs),which directly affect the output performance of SOFCs.In this paper,the characteristics of the thinning process of zirconia electrolyte are introduced.The effects of sintering additives,binder systems and slurry rheology on zirconia slurry are analyzed in detail.The influences of tape casting process parameters including casting speed and drying environment on the thickness and quality of zirconia green tapes are summarized.The advanced sintering me-thods of zirconia green tapes are described,and the effects of electrolyte thickness and structure on the density and ionic conductivity of zirconia electrolyte films are discussed.Finally,the research direction of tape casting process for preparation of high-quality zirconia thin films has been prospected.
