Abstract:

以硝酸盐和氧化物为原料,通过凝胶浇注法制备Y0.1Sm0.1Ce0.8O1.9(YSCO)电解质粉末,并将一定量的YSCO与NiO粉末机械混合均匀得到NiO-YSCO粉体,对YSCO粉末相组成及YSCO和NiO粉末的粒度进行了表征.以所获得的NiO-YSCO粉体为原料通过成型烧结制备Ni/YSCO阳极材料,并以NiO/YSCO为阳极材料、YSCO为电解质通过共压法制备SOFC单电池,对NiO/YSCO阳极烧结体和单电池的组织及性能进行了测试分析.实验结果表明,YSCO和NiO粉末的中位径d50分别为1.757和3.577mm,均为微米级.在1400℃烧结4h的NiO/YSCO烧结体的孔隙率为11.85%,还原后为20%.1400℃烧结的NiO/YSCO试样经还原得到的Ni/YSCO试样在800℃下的电导率约为250S/cm.以此为阳极的SOFC单电池性能良好,在700℃工作温度下,单电池的开路电压为0.689V,最大功率输出为153.1mW/cm2.
