anodes for solid oxide fuel cells (SOFCs) fueled with dimethyl ether (DME) were prepared. The molar ratio of Ni to Fe was 9/1, 8/2, 7/3, and 5/5, respectively, and the weight percentage of in the electrode was 75%. The increase in the amount of Fe improved the sintering of the electrode, which led to a change in the microstructure of the electrode and electrode/electrolyte interface dramatically. The electrodes showed good activity and stability for DME oxidation without obvious coke deposition, which could be a kind of novel anode for DME SOFCs based on lanthanum gallate electrolytes.
