制备了Ag与Gd掺杂的氧化铈(GDC)复合的电极材料。采用氧化钇稳定的氧化锆(YSZ)为电解质,Ag-GDC为阴极和阳极,组装成固体氧化物燃料电池(SOFC),采用担载5%(质量分数)Fe的活性炭为SOFC的燃料,对此直接碳SOFC(DC-SOFC)的输出性能及阻抗谱进行测试,并与采用传统阴极(掺Sr的锰酸镧与YSZ的复合材料)的DC-SOFC性能进行了比较,发现Ag-GDC具有更好的性能。采用扫描电镜(SEM)对电池的微观结构进行了分析,并就其对电池性能的影响进行了分析。
Ag and Gd doped ceria (GDC) composite electrode materials were prepared. (YSZ) as electrolyte, Ag-GDC as cathode and anode, assembled into solid oxide fuel cell (SOFC), using activated carbon loaded with 5% (mass fraction) Fe as SOFC fuel, The output performance and impedance spectrum of this direct carbon SOFC (DC-SOFC) were tested and compared with the DC-SOFC performance of a conventional cathode (Sr-doped lanthanum manganate and YSZ composite) and found that Ag-GDC had Better performance. The microstructure of the battery was analyzed by scanning electron microscopy (SEM) and its influence on the battery performance was analyzed.
