Abstract
A polymer electrolyte membrane for a fuel cell includes a polymer matrix comprising a cross-linked curable oligomer with nano-sized proton conductive polymer particles in the polymer matrix. The curable oligomer may include unsaturated functional groups at each end of a chain, and may further include 3 to 14 ethylene oxides. The proton conductive polymer nano particles may include fluorine-based proton conductive polymer nano particles, non-fluorine-based proton conductive polymer nano particles, hydrocarbon-based proton conductive polymer nano particles, and combinations.
