Study on the Properties of NiO/Ce_(0.7)La_(0.3)O_(1.85) Composite Anode Material for IT-SOFC

以La(NO_3)_3、Ce(NO_3)_3、Ni(NO_3)_2和有机燃料为原料,采用低温燃烧法制备一系列不同NiO含量的NiO/ Ce_(0.7)La_(0.3)O_(1.85)复合阳极粉体,对制备的阳极材料的显微结构、电导性能、热膨胀性能以及电化学催化活性进行了全面的研究。结果表明:具有很好的微观均匀性,较高的电催化活性。

NiO/Ce0.7La0.3O1.85 ceramics has been prepared by the low temperature combustion method using La（NO3）3, Ce（NO3）3, Ni（NO3）2 and organic fuel as raw materials. The conductivity, the expansion behavior and the electrochemical properties were investigated in detail .The results show that the anode prepared by combustion method has more homogenous microstructure and higher electrochemical activity.
