A process for producing a polymer electrolyte membrane, comprising coating at least one major surface of a porous base material with a solution of polymer electrolyte, applying tension (F, kg/cm) of the range of the formula: 0.01 <= F <= 10 (A) to the coated porous base material and laminating the porous base material with a support material; and an apparatus therefor. In this process, a polymer electrolyte membrane free from wrinkling, etc. and thus excelling in appearance can be continuously produced.
L'invention porte sur un procédé de production d'une membrane d'électrolyte polymère, ce procédé consistant à recouvrir au moins une surface principale d'un matériau de base poreux avec une solution d'un électrolyte polymère, appliquer une tension (F, kg/cm) de la plage de formule (A) : 0,01 <= F <= 10 sur le matériau de base poreux et laminer le matériau de base poreux avec un matériau de support. L'invention porte également sur un appareil permettant de réaliser ce procédé. Dans ce procédé, une membrane d'électrolyte polymère exempte de plissement et analogue et ayant un excellent aspect peut être produite en continu.
