摘要：
IT-SOFC composite anode material Ce0.8Ca0.2O2-La0.7Sr0.3Cr0.5Mn0.5-x,CoxO3-delta(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 mu m) was obtained after sintering the predecessor at 1350 degrees C for 5 h. Conductivity testing show that the conductivity of CDC-LSCMCo increases with the Co content increasing when the temperature is above 750 degrees C; while at 800 degrees C the conductivity is 10.5 S.cm(-1) and 0.7 S.cm(-1) in air and H-2 atmosphere, respectively. Good chemical-thermal compatibility between CDC-LSCMCo and La0.9Sr0.1Ga0.8Mg0.2O3-delta (LSGM) was confirmed via XRD and SEM. CDC-LSCMCo is a promising anode material of SOFC for its excellent properties at intermediate temperature.
