中文摘要：

采用甘氨酸-硝酸盐法制备了Ce0.8Gd0.2O1.85(GDC82)阳极材料。用TGA-DSC对前驱体物料烧结过程进行分析。用XRD,SEM,直流四探针法,TPR等技术对材料的性能进行表征。前驱体物料经燃烧后,900℃下烧结4 h后,得到单一萤石结构的材料。在50~850℃范围内,GDC82材料在空气气氛下的电导率整体较小,且随温度的升高变化不大,在850℃为0.05 S.cm-1。GDC82在H2气氛下的总电导率整体增加,且随温度的升高而迅速增加,850℃达到0.4 S.cm-1。GDC82与电解质材料La1-xSrxGa1-yMgyO3-δ(LSGM)混合物在1200℃下烧结15 h后,有少量MgCe杂相生成。GDC82与La1-xSrxCr1-yMnyO3-δ(LSCM)阳极材料化学相容性较好。GDC82对氢气和甲烷具有较好的催化氧化效果。

英文摘要：

The Ce0.8Gd0.2O1.85(GDC82) anode materials were prepared by glycine-nitrate method(GNP).The reaction process of the GDC82 materials were characterized by thermogravimetric analysis(TGA) and differential scanning calorimetric(DSC) method.The properties of GDC82 materials were measured by using X-ray diffraction(XRD),scanning electron microcopy(SEM),direct current four probe(four-probe DC) and temperature process reduce(TPR) techniques methods.After the precursors were sintered at 900 ℃ for 4 h,GDC82 material...
