Abstract
A polymer electrolyte membrane including a polysilsesquioxane group-containing copolymer and an ionic conductive polymer is provided. A method of preparing the polymer electrolyte membrane and a fuel cell including the polymer electrolyte membrane is also provided. The polymer electrolyte membrane has improved ion conductivity and an improved ability to suppress methanol crossover, and therefore can be used as an electrolyte membrane for a fuel cell, including a direct methanol fuel cell.
