Dimethyl ether （DME） reforming has important significance for the generation of hydrogen rich fuel cell feeds for fuel cell applications. The research progress in dimethyl ether reforming technologies for hydrogen production, including catalysts and deactivation mechanismes, was sumarried and reviewed. It was pointed out that the futher directiones are developing the bifunctional catalysts with high catalytic activity at low temperature and the compact, light weight, autothermal reforming systems with quick startup.
