Abstract: Advances of ionic liquid polymer electrolytes for high-temperature proton exchange membrane fuel cells and their application to high-temperature proton exchange membrane fuel cells are reviewed. The existing problems of this type of electrolyte are pointed out，including imidazole type ionic liquid poison Pt base catalysts and the long-term stability of ionic liquid in composite membrane. The future development of ionic liquid polymer electrolyte used for high temperature proton exchange membrane fuel cells is prospected. It is recommended to develop new ionic liquid polymer electrolyte compatible with Pt based catalysts and to prevent the loss of ionic liquids in the composite membrane，so as to improve the performance and long-term stability of high temperature proton exchange membrane fuel cell and then to improve the life of high temperature fuel cell.

Key words: high temperature proton exchange membrane fuel cells, ionic liquid, polymer electrolyte
