摘要：

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。

Using active carbon fiber as template, perovskite material SrMoO4 was synthesized by hard template method, which was impregnated with Gd0.2Ce0.8O1.9(GDC) to prepare the composite anode material GDC–SrMoO4–YSZ. The power performances of the solid oxide fuel cells fabricated with SrMoO4–YSZ and GDC–SrMoO4–YSZ as anode were measured. The effect of different mass ratio of anode composition material under different impregnation sequence was researched to achieve better electrical performance. Using CH4 as fuel gas at 800 ℃, when the impregnation of GDC in SrMoO4 was 50%, the SrMoO4 and YSZ mass ratio of 5:5 in anode shows the maximum power density of 317.15 mW/cm2; When the impregnation of GDC in SrMoO4–YSZ was 50%, corresponding single cell displayed best performance and achieved a maximum power density of 361.01 mW/cm2.
