| 摘 要： | 利用固相反应法制备固体氧化物燃料电池(SOFC)的复合阳极材料NiO-ScSZ和复合阴极材料(La0.8Sr0.2)0.98MnO3(LSM),并对组装的电解质支持型单电池NiO-ScSZ-LSM进行I-V性能测试,其输出电压每0.2A为0.9V.在外加恒定电流密度(0.2A/cm2)的条件下,利用电化学测试仪测试该电池的总电压为每1 000h衰减0.02V.电流遮断法解析表明,该单电池电压衰减主要为阴极过电压所致.

| Abstract: | Cermet anode material NiO ScSZ and cathode material (La0.8Sr0.2)0.98MnO3 (LSM) were prepared via solid state reaction method. The performance electrolyte supported single cell of NiO ScSZ LSM exibited an output voltage of 0.9 V at 0.2 A described by current voltage characte
rized curve. The investigation on the endurance of the single cell indicates that the whole voltage decay is 0.02 V per 1 000 h（at a current density of 0.2
A/cm2）by electro chemical measurement. The main resource of it comes from cathodic over voltage by galvanic current interruption method. |
