摘要
以溶胶-凝胶法低温(1 100℃)制备SrCe_(0.85)Er_(0.15)O_(3-α),并与NaCl-KCl共熔体进行复合,热处理温度(750℃)远低于通常高温烧结温度(1 500℃)。XRD结果表明NaCl、KCl与SrCe_(0.85)Er_(0.15)O_(3-α)复合后没有发生化学反应。采用电化学工作站研究了复合电解质在500~700℃下干燥氮气气氛中的电导率。结果表明,温度为700℃时,复合电解质在干燥氮气气氛中的电导率达到最大值1.1×10-1 S·cm-1,远高于单一铈酸锶材料在相同条件下的电导率。H2/O2燃料电池性能测试表明复合电解质在700℃最大输出功率密度为260.8mW·cm-2。
SrCe 0.85 Er 0.15 O 3- α was synthesized by sol-gel method at 1 100 ℃ and selected to compound with NaCl-KCl. The heat-treated temperature （750 ℃） is much lower than the conventional sintering temperature （1 500 ℃） of single cerium strontium material. XRD pattern showed that there has no reaction between SrCe 0.85 Er 0.15 O 3- α and NaCl-KCl. The highest conductivity was observed to be 1.1×10 -1 S·cm -1 at 700 ℃ which is much higher than that of single cerium strontium material. The H 2/O 2 fuel cell of the composite electrolyte generated the maximum power density of 260.8 mW·cm -2 at 700 ℃.
