Abstract:

The development of low?cost and long?life platinum based catalysts is the key to the commercialization of proton exchange membrane fuel cells.Platinum based intermetallic compounds are considered to be the ideal choice for fuel cell catalysts because of their atomic ordered structure and unique catalytic properties.The latest progress on the preparation of platinum based intermetallic compounds catalysts was reviewed,including direct annealing,shell?assisted annealing,template?assisted annealing and solvothermal method.The application of platinum based intermetallic compounds catalysts in catalytic oxygen reduction reaction was discussed.There is still a lack of simple and efficient preparation methods and large?scale production technology for the preparation of intermetallic compound catalysts.Therefore,it is of great significance to accelerate the development of new preparation methods for the preparation of intermetallic compound catalysts to promote the practical application of platinum-based ordered catalysts.

Key words: fuel cell, catalyst, intermetallic compounds, heat treatment
