Research progress of alloyed electrocatalysts for low temperature fuel cell

The catalyst for low temperature fuel cell is still the platinum,which is expensive and lack of resource.And this is one of the reasons that cause the high cost of proton exchange membrane fuel cell(PEMFC) and direct methane fuel cell(DMFC,which significantly limits their wide use.The applying of platinum alloyed catalysts can reduce the amount of platinum and the alloyed structure is favorable for enhancing the catalytic activity.The mechanism of the alloy catalysts on the anode and cathode for the low temperature fuel cell was introduced.The deposition-reduction thermal treatment,the improved microemulsion,microwave and some new technologies and methods of preparation of alloyed catalysts in recent years were reviewed mainly.The effect of the alloying elements,the metal precursor,atomic composition,temperature of the heat treatment and the pH value on the catalytic activity were summarized.
