摘要:  采用流延法制备Ni/YSZ阳极支撑体 YSZ电解质复合膜素坯.经等静压,共烧结而得到的复合膜,其YSZ电解质层的厚度在1530μm之间,面积大于100cm2.再将由柠檬酸盐法合成的Ce0.8Sm0.2O1.9(CSO)和固相法合成的La0.6Sr0.4CoO3(LSCO)相继沉积到YSZ膜上形成有CSO中间层的复合阴极,从而构成Ni/YSZ/CSO/LSCO的中温平板型固体氧化物燃料(单体)电池,其中Ni/YSZ为阳极,CSO是中间层,LSCO为阴极.以H2作燃料气,O2为氧化气,850℃下,该单电池开路电压达1.1V,最大输出功率密度0.2W/cm2.本文还对该单电池复数阻抗谱进行了分析讨论.

Abstract: Tape cast method was applied to prepare green sheets of Ni/YSZ anode supported YSZ thin film. After isostatic pressure treatment and cosintering, the YSZ film on the Ni/YSZ anode was gas-tight dense, and 15~30 μm thick. The area of the composite film was over 100 cm~(2). A Ce_(0.8)Sm_(0.2)O_(1.9 )(CSO) interlayer was sintered on to the YSZ electrolyte film to protect La_(0.6)Sr_(0.4)CoO_(3 )(LSCO) cathode from reaction with YSZ at high temperatures. The LSCO cathode layer was screen printed onto the CSO interlayer and sintered at 1 200 ℃ for 3h to form a single cell. The obtained single cell was operated with H_(2) as fuel and O_(2) as oxidant. The cell performance was measured and impedance contributions were discussed.
