摘要：

为发展中温固体氧化物燃料电池(IT-SOFC)的阴极材料,用柠檬酸络合法合成了Ba0.5Sr0.5Co0.8Fe0.2O3-δ(BSCF)粉体,并在BSCF中加入一定量的金属Ag作为SOFC的阴极材料.高温电阻测试表明复合阴极材料(BSCF-Ag)比纯BSCF材料具有较高的电导率.同时用交流阻抗法研究了BSCF-Ag复合阴极材料的性能,实验结果表明BSCF-Ag复合阴极材料的极化电阻明显小于纯BSCF,在750℃BSCF的极化电阻为0.41Ω.cm2,而BSCF-Ag的电阻仅为0.12Ω.cm2,约为BSCF的1/4.这标志着参杂Ag的BSCF阴极材料的性能明显优于纯BSCF材料.
