Research progress of direct dimethyl ether fuel cells

A concise introduction of principle of direct dimethyl ether fuel cells (DDFC) and properties of dimethyl ether (DME) was provided. The mechanism for electrocatalytic oxidation of dimethyl ether on platinum in recent literature was reviewed and the different viewpoints of mechanism among authors were analyzed. Furthermore, the influence of temperature, humidity of dimethyl ether and catalysts for anode, solid polymer membrane on performance of DDFC in the literature was also summarized. Several suggestions on the study directions of DDFC in future work were discussed.
