Abstract

Ni_1-xCu_x-Ce_0.8Gd_0.2O _1.9 cermet anodes were co-synthesized by a glycine nitrate process (GNP). While the polarization resistance in an H₂ atmosphere increased with increasing Cu content, both electrical conductivity and the amount of carbon deposits were reduced by Cu alloying. The anode polarization resistance in CH₄ fuel decreased with increasing Cu content, which strongly correlates with the carbon deposition behavior. Cu doping significantly improved the electrochemical performance in CH₄ fuel.
