应用丝网印刷和共烧结制备LaNi0.6Fe0.4O3-δ(LNF)/Sc0.1Zr0.9O1.95(ScSZ)/LaNi0.6Fe0.4O3-δ对称电池.以硝酸铈和硝酸钆为原料、柠檬酸为燃料,采用燃烧法制备质量分数为21.3％的Gd0.2Ce0.8O2(GDC)包覆的LNF阴极.电化学阻抗谱(EIS)表明:在750℃工作温度下,当无Cr基合金接触时,质量分数21.3％的GDC包覆的LNF经过1 200 h的搁置,其极化电阻由0.13 Ω·cm2增加至0.40 Ω·cm2,而纯LNF经过500 h的搁置,极化电阻由0.70 Ω·cm2增加至2.36Ω·cm2,GDC的包覆加速了气体/阴极/电解质三相界面反应区的扩散过程,降低了阴极极化电阻;当有Cr基合金接触时,相对于质量分数为21.3％的GDC包覆的LNF阴极,LNF/ScSZ界面处沉积出大量Cr2O3,减缓了活性粒子在三相界面处的扩散,故其极化电阻远大于相同条件下质量分数为21.3％的GDC包覆的LNF阴极的极化电阻,质量分数为21.3％的GDC包覆的LNF阴极具有较佳的抗铬污染性能.
