<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a polymer electrolyte membrane capable of suppressing occurrence of form failure such as wrinkles and deformation (especially, fine membrane deformation ). <P>SOLUTION: The method of manufacturing an aromatic hydrocarbon-based polymer electrolyte membrane includes a process to obtain a casting film of a polymer electrolyte precursor having an acid group to form a salt, a process to obtain the polymer electrolyte precursor by removing solvent from the casting film, a process to obtain a polymer electrolyte membrane by converting the salt of the polymer electrolyte precursor into protons, a process to clean the polymer electrolyte membrane, and a process to adjust the moisture content of the polymer electrolyte membrane after rolling up the polymer electrolyte membrane after cleaning, in this order. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
