CeO_2在固体氧化物燃料电池阳极Cu-SDC中的作用

The Role of CeO_2 in the Anode Cu-SDC of Solid Oxide Fuel Cell

采用甘氨酸-硝酸盐方法制备Cu-SDC和Cu-CeO_2-SDC燃料电池阳极,对性能进行了测试和分析。结论给出在Cu-SDC阳极材料中加入CeO_2,使电池的过电位下降,输出功率提高。在600℃时,Cu-CeO_2-SDC样品的电流密度达到了0.1 Acm^(-2),阳极过电位达到0.16 V。800℃时,电池输出功率由33 m W/cm^2提高到54 m W/cm^2。

Cu-SDC and Cu-CeO2-SDC were synthesized by sol-gel method and the electrical properties were tested and compared.The addition of CeO2 in Cu-SDC anode,electrode overpotential decrease,current density increase.the current density of Cu-CeO2-SDC anodeis is 0.1 Acm-2 and composite anode overpotential is 0.16V at 600℃.The current density increase from 33 mW/cm 2 to 54 mW/cm2 at 800℃.
