项目摘要
The solid-oxide-fuel-cell performance using a cermet-type anode, which consists of the Ni-Co solid-solution alloy particles dispersed in the matrix of samaria-doped ceria (SDC) grains or that of yttria-stabilized zirconia (YSZ) grains, has been investigated. The anodic polarization resistance of the Ni_<0.5>Co_<0.5>-SDC (or YSZ) anode was low for H_2 and CH_4 using an SDC electrolyte disk or a scandia-stabilized zirconia (ScSZ) electrolyte disk. The microstructural characterization of these cermet anodes revealed a proof of an enhancement effect on the electrochemical oxidation of CH_4. In the case of using the SDC electrolyte, the oxide ions supplied through the SDC electrolyte contribute to the oxidation of methane even under the open circuit condition, which is specific to the mixed ionic electronic conduction of SDC. It was found that the redox reaction occurring at surface of ceria-based oxides enhances the oxidation rate of methane with the support of Ni_<0.5>Co_<0.5> particles dispersed among the electrolyte grains.
本文研究了由Ni-Co固溶合金颗粒分散在掺杂钐的二氧化铈(SDC)颗粒或钇稳定的二氧化锆(YSZ)颗粒基体中的金属陶瓷型阳极的固体氧化物燃料电池性能。采用SDC电解质盘或ScSZ电解质盘制备的Ni_<0.5>Co_<0.5>-SDC(或YSZ)阳极对H_2和CH_4的阳极极化电阻较低。这些金属陶瓷阳极的微观结构表征表明,它们对CH_4的电化学氧化有增强作用。在使用SDC电解质的情况下,即使在开路条件下,通过SDC电解质供应的氧化离子也有助于甲烷的氧化,这是SDC混合离子电子传导所特有的。结果表明,在分散于电解质颗粒中的Ni_<0.5>Co_<0.5>颗粒的支持下,氧化还原反应发生在氧化铈基氧化物表面,提高了甲烷的氧化速率。
