中文摘要：

采用甘氨酸-硝酸盐法（GNP法）一次性合成固体氧化物燃料电池复合阳极材料Ce0.8Ca0.2O2-La0.7Sr0.3Cr0.5M0.5-xCocO3-δ（CDC—LSCMCo）。XRD、SEM和EDS分析结果表明：1350℃下烧结5h能够得到单一萤石一钙钛矿结构且粒度较小（1／am左右）的复合阳极粉体。电导率的测试研究发现，温度大于750℃时，电导率随Co含量的增加而增大。800℃时，CDC—LSCMCo0.15分别在空气与氢气气氛下的电导率分别为10．5和0．7s．cm^-1。SEM和XRD分析表明：CDC-LSCMCo与La0.9Sr0.1Ga0.8Mg0.2O3-δ电解质材料有很好的热与化学相容性，是一种应用前景良好的IT-SOFC阳极材料。

英文摘要：

IT-SOFC composite anode materialCe0.8Ca0.2O2-La0.7Sr0.3Cr0.5M0.5-xCocO3-δ（CDC-LSCMCo） was synthesized in one-step by glycine nitrate process （GNP）. The results from X-ray diffraction （XRD）, scanning electron microscopy （SEM） and energy dispersive X-ray spectroscopy （EDS） indicate that the composite anode powder with single fluorite-perovskite phase and small grain size （about 1 μm） was obtained after sintering the predecessor at 1350 ℃ for 5 h. Conductivity testing show that the conductivity of CDC-LSCMCo increases with the Co content increasing when the temperature is above 750 ℃; while at 800 ℃ the conductivity is 10.5 s.cm^-1 and 0.7 S·cm^-1 in air and H2 atmosphere, respectively. Good chemical-thermal compatibility between CDC-LSCMCo and La0.9Sr0.1Ga0.8Mg0.2O3-δ （LSGM） was confirmed via XRD and SEM. CDC-LSCMCo is a promising anode material of SOFC for its excellent properties at intermediate temperature.
