通过高温固相反应制备了混合离子(质子和氧离子)导电性陶瓷BaCe~0~.~9Y~0~.~1O~3~-~α,以该陶瓷作固体电解质,pt作电极材料组成氢-空气燃料电池,测定了该燃料电池高温(600~1000℃)下放电时的电压-电流特性。结果表明,该燃料电池具有稳定的放电性能,输出功率密度高,1000℃下的最大短路电流密度和输出功率密度分别为980mA·cm^-^2和0.22mW·cm^-^2,高于同类燃料电池的性能。

Using mixed proton and oxide-ion conductor with BaCe~0~.~9Y~0~. ~1O~3~-~α as a solid electrolyte, hydrogen-air fuel cell was constructed. The performances of the cell were investigated at temperatures between 600 and 1000℃. The maximum short-circuit current density and the maximum power output density of this cell at 1000℃ were about 980mA·cm^-^2 and 0.22mW·cm^-^2, respectively. These performances were significantly better than those of other solid oxide fuel cells based on BaCe~0~.~9Y~0~.~1O~3~-~α(M=Sm, Gd, Yb, Nd, etc.) reported so far.
