Abstract:
The present invention relates to a polymer electrolyte membrane for a fuel cell, a method for manufacturing the polymer electrolyte membrane, a membrane-electrode assembly for a fuel cell including the polymer electrolyte membrane, and a fuel cell system including the membrane-electrode assembly. The polymer electrolyte membrane includes a proton-conductive polymer membrane including a polymer micelle inside a hydrophilic channel. Herein, the micelle includes a vinyl-based polymer obtained from polymerization of a vinyl-based monomer and an anionic surfactant surrounding the vinyl-based polymer.
