摘要： 以固相反应方法制备了SrCe0.90Gd0.10O3含质子导电的固体电解质,对以该材料为电解质的燃料电池的性能进行了研究.结果表明,电池的输出电压强烈依赖于温度,其原因是电池电解质具有复杂的导电机理,通过对其在燃料电池工作气氛下的阻抗谱研究,揭示了该材料导电类型随气氛变化的规律,并从机理上对此实验现象加以解释.根据实验结果,确定了电解质材料的最佳使用条件.

Abstract: Solid electrolyte of SrCe0.9 Gd0.1 O3 with proton conduction was sintered by solid reaction method, and the properties of a fuel cell with this material as the electrolyte were also investigated. The results show that the output voltage depends on temperature. The phenomena should be contributed to the complex conducting mechanism of this electrolyte. By studying the impedance spectroscopy of the electrolyte material in the working environment of a fuel cell, we found that the conducting types vary with the variation of atmosphere. According to the results of this experiment, the best working condition of this kind of electrolyte was also determined.

Key words: Proton conductor, Fuel cell, Impedance spectroscopy, SrCeO3
