Abstract:用柠檬酸溶胶-凝胶法合成了Ce0.85Gd0.15O2-δ(CGO),用共沉淀法合成了掺摩尔分数为11%Sc2O3稳定的ZrO2(scandium oxide-stabilized zirconia,ScSZ)电解质材料.通过X射线衍射和透射电镜对电解质材料的物相、形貌和成分进行表征.结果表明:CGO和ScSZ在各自的煅烧温度下均形成了单-的立方萤石结构晶态;ScSZ颗粒的粒径约为20nm.用共压法分别制备了以NiO-CGO阳极支撑的CGO单层电解质和ScSZ/CGO复合电解质的基体,并在基体上涂覆阴极制作单电池.在650~800℃范围内测试单电池的电性能.结果表明:ScSZ/CGO双层电解质电池的开路电压和最大功率密度均高于单层CGO电解质电池;在800℃电流密度和功率密度达到最大值,分别为677.5 mA/cm2和197.3 mW/cm2.说明SeSZ/CGO双层电解质有效地提高了电池的性能.
