    摘要:

    本研究分别采用水系流延法制备多孔YSZ流延片与有机流延法制备YSZ电解质薄膜,经叠压共烧后获得多孔YSZ/致密YSZ薄膜复合基体。通过化学浸渍法分别在复合基体多孔YSZ层内浸渍了Fe(NO3)3、Co(NO3)2和Ni(NO3)2溶液来制备浸渍阳极SOFC单电池(以LSM+YSZ为阴极)。初步研究了铁系阳极催化剂的性能,测试了不同阳极SOFC单电池在不同温度下的电性能并采用SEM观察了不同浸渍阳极的形貌。进一步对Co-YSZ和Ni-YSZ阳极单电池的抗积碳性能进行了测试与比较。实验结果表明:在氢气气氛中钴的催化活性最高,镍次之,铁最差;在乙醇气氛中钴的催化活性仍要好于镍,而且Co-YSZ阳极单电池的抗积碳性要明显优于Ni-YSZ阳极单电池。铁系催化剂中Co的催化性能和抗积炭性能最佳。

    Abstract:

    In this paper,the porous YSZ film was prepared by aqueous tape casting and the YSZ electrolyte film was prepared by organic tape casting. The porous YSZ-compact YSZ film composite was prepared via the stack pressure co-firing of the porous YSZ film and YSZ electrolyte film. The impregnated anode SOFC single cell was prepared by chemical impregnation method with the solution of ferricSnitrateS、cobalt nitrate and nickel nitrate was impregnated in porous YSZ layer of the composite matrix. The performance of iron-based anode catalysts was studied,the electrical properties of different anode SOFC single cell at different temperature were tested and the morphology of the anode was observed by SEM. The anti-carbon performance of Co-YSZ and Ni-YSZ anode single cell was tested and compared. Experimental results show the catalytic activity of cobalt in the hydrogen atmosphere was the highest,the nickel is the second,and the iron is the worst. The catalytic activity of cobalt in alcohol atmosphere was still better than that of nickel, and the anti-carbon performance of Co-YSZ anode single cell was better than that of Ni-YSZ single cell. The catalytic activity and the anti-carbon performance of cobalt in Iron-based catalyst were best.
