La0.85Sr0.15Cr0.9Ni0.1O3-δ-Ce0.8Sm0.2O1.9 as an Anode Material of SOFC

较低的催化活性大大地限制了La0.85Sr0.15Cr0.9Ni0.1O3-δ(LSCN)作为直接碳氢化合物燃料SOFC阳极材料的应用.本文尝试用Pechini法合成LSCN,并按重量比1:1向其中加入纳米Ce0.8Sm0.2O1.9(SDC)作为阳极材料.经1500℃高温烧结12h后,LSCN与SDC以及电解质YSZ仍可以保持各自独立的相结构.加入SDC没能提高阳极的电导率,但由于改善了阳极电解质界面的结合状况,扩展了电极反应的活性区域,使阳极材料的极化性能有了提高.显微结构观察显示,LSCN-SDC阳极在甲烷气氛中使用时没有碳沉积现象.
