英文摘要：

The 50%NiO-（50-x）%Ce0.8Sm0.2O1.9（SDC）＋x%La0.9Sr0.1Ga0.6Mg0.2O3-α（LSGM） （x=0, 10, 20, 30, 40） anode supported cells were fabricated by dry-pressing process using LSGM as electrolyte and 85% LSCF＋15% GDC as cathode. The crystal microstructure of cells was observed by scanning electron microscope （SEM）. The crystal forms of the anode materials which had been sintered 4 h in 1 250 ℃ were analyzed by X-ray diffraction. The composite anode cells were tested and compared with un-composite anode cell from 350-600 ℃ every 50 ℃, using dry natural gas as fuel and oxygen as oxidant. The results of experiment show that the anode of the cells has good structure of hole. The 50% NiO-30% SDC＋20% LSGM anode supported-cell has the best electrochemical performance among the five cells. The composite anode cell has better catalyze for natural gas than un-composite anode cell. The composite anode cell of maximum current density and power density at 600 ℃ are 229.32 mA/cm^2 and 45.86 mW/cm^2, respectively.
