POLYMER ELECTROLYTE MEMBRANE FOR FUEL CELL, MEMBRANE-ELECTRODE ASSEMBLY FOR FUEL CELL INCLUDING SAME, AND FUEL CELL INCLUDING SAME

摘要

A polymer electrolyte membrane for a fuel cell includes a cross-linking polymer in which a polyhedral oligomeric silsequioxane (POSS) is cross-linked with a hydrocarbon-based polymer and a membrane-electrode assembly for a fuel cell includes the polymer electrolyte membrane.
