ABSTRACT:
A polymer electrolyte membrane for a fuel cell that can maintain a stable performance for a long time, a method of manufacturing the same, and a fuel cell employing the same. The polymer electrolyte membrane includes at least one kind of a basic polymer and an acidic dopant. A dimensional change in the planar direction of the electrolyte membrane between a wet state and a dry state is 5% or less.
