Polymer electrolyte membrane having excellent durability |
摘要 |
A polymer electrolyte membrane for a polymer electrolyte fuel cell, that overcomes disadvantages of the conventional polymer ion-exchange membranes including fluorine-based polymer electrolyte membranes and can maintain cell characteristics even in use over a long period of time (e.g., several thousand hours). The polymer electrolyte membrane comprises a fluorine polymer substrate having grafted thereon monomers having sulfone groups as a cation-exchange group, wherein a main chain of the graft chain comprises a hydrocarbon or a partially fluorinated hyd |
