Solid oxide fuel cells (SOFCs) with a high energy conversion efficiency and low emissions are considered as promising substitutes for traditional thermal power devices. Compared with fuel cells operated at a low temperature with H<sub>2</sub> as the fuel, one major advantage of SOFCs is that they can use hydrocarbon fuels which are readily available, low-cost and convenient for storage and transportation. The performance of hydrocarbon-fueled SOFCs depends significantly on the kinetics of the electrochemical oxidation of the fuels, and the development of anode materials with a sufficient catalytic activity and a high resistance to coking is highly demanded. Aiming to utilize methane and methanol as the fuels of SOFCs directly, in the last decade, we have focused on anode materials and anodic electrochemical processes, involving the modification of conventional Ni-based cermet anodes with the doping of transition metal and rare earth metal ions, and the development of novel double-perovskite manganite anode materials. Our research focus has been mainly on the relationships between “crystal and electronic structure-charge transfer-catalytic activity”, and major breakthroughs in novel anode materials with high activity and stability have been made in 600-800 <sup>o</sup>C with non-hydrogen fuels.
