| 摘 要： | 利用甘氨酸 硝酸盐燃烧法制备不同浓度Co掺杂的La0.8Sr0.2Ga0.8-xMg0.2CoxO3-δ固体氧化物燃料电池电解质材料, 并对其晶体结构、 形貌以及电学性能进行表征. 结果表明: 随着Co掺杂量的增加, 样品无明显杂相峰, 其谱峰略向小角度一侧移动, 晶胞体积略增大,
平均粒径逐渐减小; Co掺杂对电导率影响显著, 晶粒电导率是导致样品总电导率升高的主要因素.

| Abstract: | TheLa0.8Sr0.2Ga0.8-xMg0.2CoxO3-δ electrolytes for solid oxide fuel cell (SOFC) with different concentrations ofCo were prepared by glycine nitrate combustion method, and the crystal structure, morphology and electrical properties were characterized. The results show that, with the increase of Co doping, there is no obvious heterophase peak in the sample, the spectral peaks shift slightly to the side of small angle, the cell volume increases slightly, and the average partical size decre
ases gradually. Co doping has a siginificant effect on the conductivity, and the grain conductivity is the key factor to increase the total conductivity of the sample. |
