Abstract: Using hydrocarbons as a fuel is an inevitable trend for the development of solid oxide fuel cell (SOFC) technology. Thus it is necessary to develop a new SOFC anode material that can directly use the hydrocarbon fuels. CeO2-based composite material has been widely used as an essential part of SOFC anode materials due to its good catalytic properties, high redox ability and elevated oxygen storage capacity. This paper systematically summarized and analyzed the physical and electrochemical properties of Mn, Fe, Cu, Co and Ni doped or co-doped CeO2 as anode materials of SOFC, and the future developments of CeO2-based composite oxides are proposed.
Key words: hydrocarbons; CeO2-based material; anode; solid oxide fuel cell; electrochemical oxidation
