| Abstract: | Low-temperature solid oxide fuel cell (LT-SOFC) has caught a lot of attention due to its good propertyof high output power at low temperatures. However, the stability of such fuel cells needs to be further improved forcommercial applications. In this paper, NCAL and SDC were studied which were common materials in LT-SOFCsystems. The co-compressed fuel cell was tested in OVC processes. After the failure of the cell, its microstructuredevelopment was analyzed to study the possible mechanism causing the failure. Plasma spray technology was alsoused 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. |
