Abstract
MCuCo40 (CuCo-CeO 2, 40 at.% metal load, 1/1 Cu–Co atomic ratio), synthesised by inverse microemulsion method, was evaluated as the anode for SOFC at intermediate temperature. This material presents optimal physicochemical and electrical characteristics as well as excellent thermal and chemical compatibility with 8YSZ electrolyte. The evaluation of single-cell performance, with 8YSZ electrolyte and LSM cathode and this anode material, operating in H 2 and methane fuels, in comparison with a similar single-cell using Cu-ceria-based anode allows to conclude that the substitution of copper (20 at.%) by cobalt in the anode composition enhances the single cell performance as well as reduces the carbon deposit formation on the anode after running on hydrocarbon fuels (methane).
