中文摘要：

采用浸渍法,在阳极支撑型固体氧化物燃料电池Ni/YSZ阳极上制备纳米Ru层。并研究不同Ru浸渍量对单电池的电性能的影响。实验结果表明：采用化学浸渍法能成功制备显微结构良好的Ru催化层,纳米级珍珠状的Ru颗粒均匀的分散于Ni-YSZ阳极材料表面。以乙醇蒸汽（n H2O/CH3CH2OH=3∶1）为燃料,800℃的测试温度下,浸渍了0.8wt.%Ru的Ru-Ni-YSZ YSZ Ag单电池获得最大功率密度可达304 m W/cm2,即Ru层的添加可以提高单电池的电性能。通过10 h的运行,显示添加了Ru层的电池的电性能及抗积碳性能获得明显提高。

英文摘要：

A nano Ru catalytic layer on the Ni -YSZ anode-supported solid oxide fuel cell was obtained by impregnation method. The influences of different Ru content on the electrical properties of a single cell were studied by SEM, EDS and the electrochemical workstation. The research result revealed that a functional nano Ru catalytic layer was gotten on Ni-YSZ anode by impregnation method. The pear-like nano Ru particles were uniformly dispersed on the surface of Ni-YSZ anode materials. With 0.8 wt.% Ru impregnated in ethanol （nH20/ CH3CH2OH=3：1） fuel at 800℃, the electrical performance of Ru-Ni-YSZ ｜｜ YSZ ｜｜Ag single cell was 304mW/cm^2. The 10 hours＇ running test showed the electro catalytic activity and anti-carbon deposition of the cell obviously improved.
