The development of an economically feasible Solid Oxide Fuel Celltechnology has driven the research activity in this area toward thereduction of their operating temperature. New anode materials, with highelectrocatalytic activity and resistance to coke deposition whenhydrocarbons are used as fuel, have to be developed. The aim of this workis to give a contribution in this area by studying the effect of Nisubstitution by Cu in the NiO (60 wt.%)/Ce0.9Zr0.1O2 cermet recentlyproposed as a possible anode material. It was observed that the partialreplacement of Ni by Cu has produced solids with high reducibility,excellent catalytic and electrocatalytic performances and higher resistanceto carbon deposition in the operation with CH4.
