中文摘要: 低温固体氧化物燃料电池 (LT-SOFC) 因具有放电功率高、 性能优异而广受关注， 但目前此类电池的稳定性
尚待提高以满足商用需求。 本文使用 LT-SOFC 常用的材料体系 (NCAL、 SDC)， 采用共压法制备了样品并进行了
放电试验。 电池失效后对其组织进行了解剖， 重点分析了失效组织演变行为， 探索了引起电池失效可能的机制。
本研究还采用等离子喷涂方法在金属支撑体上制备了电极涂层， 并应用到电池片制备中。 结果表明， 通过热喷涂
技术制备电池涂层在一定程度上能够缓解电池由于结构失效造成的性能过早衰退现象。

Abstract:Low-temperature solid oxide fuel cell (LT-SOFC) has caught a lot of attention due to its good property
of high output power at low temperatures. However, the stability of such fuel cells needs to be further improved for
commercial applications. In this paper, NCAL and SDC were studied which were common materials in LT-SOFC
systems. The co-compressed fuel cell was tested in OVC processes. After the failure of the cell, its microstructure
development was analyzed to study the possible mechanism causing the failure. Plasma spray technology was also
used to make electrode coatings on porous stainless steel support, which was applied in fuel cell manufacture.
The results showed that the cell with the sprayed electrode coatings performed longer output life than that by the common method with solving the structure failure problem.
