Abstract:以活性炭纤维为模板,用硬模板法合成钙钛矿材料SrMoO4,并在SrMoO4阳极上浸渍Gd0.2Ce0.8O1.9(GDC),制备出GDC–SrMoO4–YSZ复合阳极。分别以SrMoO4–YSZ和GDC–SrMoO4–YSZ为阳极,制备了固体氧化物燃料单电池,并测试了其电性能。探究了不同浸渍次序下,阳极的材料组成对电池发电性能的影响。结果表明,以CH4为燃料,工作温度为800℃时,SrMoO4中浸渍GDC质量分数为50%,SrMoO4与YSZ质量比为5:5的阳极材料,最大功率密度为317.15 mW/cm2;SrMoO4–YSZ中GDC浸渍量为50%时,单电池性能最佳,最大功率达到361.01 mW/cm2。
