摘要：
A method for producing a polymer electrolyte membrane including: (i) a preparation step for preparing a polymer electrolyte solution by dissolving a polymer electrolyte containing an ion conductive polymer having an ion-exchange group in an organic solvent capable of dissolving the polymer electrolyte, (ii) a coating step for obtaining a polymer electrolyte membrane intermediate containing the ion conductive polymer by a solution casting method using the polymer electrolyte solution obtained in the step (i), and (iii) a washing step for washing the polymer electrolyte membrane intermediate obtained in the step (ii) by bringing the polymer electrolyte membrane intermediate into contact with a washing solvent; wherein the concentration of the organic solvent in the washing solvent brought into contact with the polymer electrolyte membrane intermediate in the washing step (iii) is 2500 ppm by weight or lower.
