摘要：

为了提高固体氧化物燃料电池在中温条件下的电性能,探索了一种双金属阳极的阴极支撑单电池。单电池以La_0.6Sr_0.4CoO₃（LSC）-Ce_0.9Gd_0.1O_1.95（GDC）为阴极支撑体,旋涂了甘氨酸-硝酸盐法制备的La_0.9Sr_0.1Ga_0.8Mg_0.2O_3-_δ（LSGM）电解质及Sm_0.2Ce_0.8O_1.9（SDC）缓冲层,涂覆了由硬模板法和浸渍法结合制备的Ni-Fe/GDC双金属阳极。对制备材料进行了XRD和微观形貌分析,单电池电化学测试在800 ℃和750 ℃下,以氢气为燃料的最大功率密度达0.73 W/cm²和0.64 W/cm²,以甲烷为燃料时达0.41 W/cm²和0.40 W/cm²。测试后的SEM表明,阳极具有多孔的微观结构,金属颗粒均匀包覆蠕虫状GDC,保证了单电池具有较高的发电性能。

Abstract:

The bimetallic anode for the cathode-supported single cell was explored to improve the electrochemical performance of intermediate temperature solid oxide fuel cell.The single cell was supported by the La_0.6Sr_0.4CoO₃（LSC）-Ce_0.9Gd_0.1O_1.95（GDC）cathode-supported body,which was coated the La_0.9Sr_0.1Ga_0.8Mg_0.2O_3-_δ（LSGM） electrolyte film and the Sm_0.2Ce_0.8O_1.9（SDC） bu-ffer layer by spin-coating,and was tape-coated the Ni-Fe/GDC composite anode.The electrolyte was prepared by glycine-nitrate process,and the anode was prepared by hard template and wet impregnation method.The prepared materials were ana-lyzed by XRD and SEM.The maximum power densities of the cell were 0.73 W/cm² and 0.64 W/cm² at 800 ℃ and 750 ℃ in hydrogen,and the values were 0.41 W/cm² and 0.40 W/cm² in dry methane,respectively.The conducted SEM showed that the anode had the porous microstructure with high specific surface and bimetallic particles were densely coated on the vermicular GDC,which resulted in the high power generation performance.

Key words: solid oxide fuel cell, cathode-supported cell, composite anode, the bimetallic anode, hard template method
