Abstract

In this work, the optimum compositions for a Cu-CeO2-YSZ anode were introduced as a solid oxide fuel cell anode structure. The minimum Cu content, a suitable infiltration technique and the optimum CeO2 amounts were determined. The continuum percolation limit of metallic Cu was demonstrated to be 30% by mass in the \YSZ\ matrix. The simultaneous and sequential impregnation of Cu and CeO2 salt solutions was investigated using \XRD\ and \SEM\ techniques. It was concluded that the phase distribution in the \YSZ\ scaffold was more efficient and that there was no chemical interaction between Cu and CeO2 during the co-calcination process with simultaneous infiltration. The \OCV\ values of the cells increased greatly with 5%, 10% and 20% CeO2 content. On the other hand, over this loading, the \OCV\ values were approximately 920
