中温固体氧化物燃料电池的ag-ysb复合阴极
Keywords: 无机非金属材料,燃料电池,复合阴极,草酸盐
Abstract:
？用草酸盐共沉淀法制备了y$_{0.25}$bi$_{0.75}$o$_{1.5}$(ysb),用x--ray衍射方法考察了其成相温度,用交流阻抗法测试了其电导率.与ag复合制成复合阴极,研究了烧结温度对复合阴极微结构的影响.同时以sm$_{0.2}$ce$_{0.8}$o$_{1.9}$(sdc)为电解质,用交流阻抗法研究ysb含量对复合阴极界面阻抗的影响.用草酸盐共沉淀制备的ysb粉,其电导率比sdc大得多.ag--ysb复合阴极疏松多孔,ag--ysb与sdc的界面结合良好,形成了足够多的三相界面,降低了界面极化电阻.ysb有一个最佳添加量,电阻最小,即电极界面性能最高.ysb的过量添加损坏ag相的连续性,降低氧的还原转化速度,使界面的电阻增大.
