Disclosed are a polymer ion exchange membrane having a self-hydration capability at a high temperature under low humidity, a method of preparing the polymer ion exchange membrane, and a polymer electrolyte fuel cell system including the polymer ion exchange membrane. The polymer electrolyte membrane includes a hydrocarbon-based proton conductive polymercoating layer, and has a nano-crack on the hydrophobic surface and thus may secure ion conductivity and self-hydration capability under low humidity and remarkably improve electrochemical performance of an electrolyte.

Polymer ion exchange membrane and method of preparing same

The present invention provides sulfonated poly(phenylene sulfide sulfone nitrile) and a polymer electrolyte membrane thereof. In particular, the present invention provides sulfonated poly(phenylene sulfide sulfone nitrile) having a triple bond at its both ends and a polymer electrolyte membrane with superior mechanical properties prepared by heating sulfonated poly(phenylene sulfide sulfone nitrile) and forming cross-links between ends of sulfonated poly(phenylene sulfide sulfone nitrile).
