摘要
采用一种新的燃烧合成陶瓷粉体的方法——硝酸盐-柠檬酸盐燃烧法低温合成中温SOFC所有元件的初始粉体并组装成单电池,电池的电解质材料为Ce_(0.8)Gd_(0.2)O_(1.9),阴极材料为掺杂一定量固体电解质的La_(0.6)Sr_(0.4)Fe_(0.8)Co_(0.2)O_3,阳极材料为固体电解质与NiO的复合材料。单电池的性能测试结果表明:单电池的输出电压和输出电流皆随其运行温度升高而增大,同时单电池的开路电压随温度升高而下降。以Ce_(0.8)Gd_(0.2)O_(1.9)电解质材料为电解质的单电池在750℃的最大输出功率密度约为85 mw/cm^2。
The electrolyte and electrode materials used in intermediate temperature solid oxide fuel cell (IT-SOFC) were synthesized by a new preparation method called nitrate-citrate process. A single solid oxide fuel cell (SOFC) was assembled, in which Ce0.8Gd0.2O1.9 (GDC) was applied as the electrolyte, La0.6Sr0.4Fe0.8Co0.2O3 doped with a certain amount of GDC was selected as the cathode material and a GDC-NiO composite powder was used as the anode material. The performance of this single cell was investigated. The test results show that the output voltage and current of the single cell was increased with increasing operating temperature, while the open-circuit voltage decreased with increasing operating temperature. Moreover, the maximum power density reached 85 mW/cm^2 at 750 ℃ when Ce0.8Gd0.2O1.9 was used as electrolyte for the single cell.
