Description
Summary:Aid of a metallic overlayer to nickel/yttrium-stabilized-zirconia (Ni/YSZ) anode is investigated in Direct Methane Fuel Cell. Copper modified nickel metallic overlayer shows high activity for fuel cell performance and good stability to coking in methane atmosphere. The copper-nickel overlayer provides advantages of material compatibility with the substrate and catalytic function on copper-modified nickel sites. The results suggest that the overlayer is effective for decomposition of methane and tolerant to coking by removal of deposited carbon via oxidation and gasification reaction. •The metallic overlayer is a simple approach to realize Direct Methane Fuel Cell.•A Cu–Ni metallic overlayer on NiO/YSZ reduces impact of coking on the anode.•Carbon is deposited on the metallic surface instead of vicinity of anode structure.
