从SOFC工作状态出发，分析了材料在氧化还原气氛中的固-气界面化学稳定性、材料间固-固界面的扩散与相互反应的特性以及外部化学物质的介入对三相界面反应等方面因素对电池性能可能产生的影响.故我国应注重探究实用的SOFC电池性能衰减材料因素.

Based on the cell operating conditions, the material factors which influence the cell performance of SOFC including the chemical stability of materials at solid-gas interface in redox atmosphere, the diffusion and reaction between the interface of solid-solid materials, and degradation caused by the external chemical substances brought into the cells at triple phase boundary are mainly analyzed. Given that under the current state of the research it is urgent to explore the material factors on degradation of cell performance to meet demands in SOFC applications.
