Thin-film electrolyte fuel cells are fabricated using strontium-zirconate-cerate solid solution whic h has both chemical stability and fairly high proton conductivity. When the film was prepared by pul sed-laser deposition method, the fuel cells thus fabricated showed high performance in the operation al temperature range of 500-700 degree C. Samarium-strontium cobaltate that have shown high cathode performance with barium cerate electrolyte was found to work well for the solid solution electrolyte.Slurry coating was tested for fabrication of thin film electrolyte, intending the use for industria 1 process. Cobalt was found to work as a sintering aid, where as the resulting electrolyte shoed ten times lower conductivity than the undoped material. On the other hand, the mixture of starting mate rial (i. e., carbonates and oxides) can become well-sintered thin film when it backed without taking the course of calcinations. Thin film thus fabricated was confirmed to work for fuel cells.In the investigation in this project, fabrication route of proton conductor fuel cells can be establ ished.

利用锆酸锶-铈酸盐固溶体制备薄膜电解质燃料电池，该固溶体具有化学稳定性和较高的质子导电性。当用脉冲激光沉积法制备薄膜时，由此制备的燃料电池在500-700 ℃的工作温度范围内显示出高性能。钴酸锶钐在铈酸钡电解质中表现出很好的阴极性能，可用于固溶体电解质，并进行了浆料涂覆制备薄膜电解质的试验，以用于工业生产。钴被发现作为烧结助剂，其中作为所得电解质的电导率比未掺杂的材料低十倍。另一方面，起始材料的混合物（即，例如，碳酸盐和氧化物）可以在不进行煅烧的情况下在背衬时成为良好烧结的薄膜。本计画之研究，可建立质子导体燃料电池之制程路线。
