MANUFACTURING METHOD OF REINFORCEMENT TYPE ELECTROLYTE MEMBRANE

摘要

PROBLEM TO BE SOLVED: To suppress generation of an air pocket and a wrinkle during manufacture of a reinforcement type electrolyte membrane.SOLUTION: A manufacturing method of a reinforcement type electrolyte membrane includes: a process of forming a laminated membrane by laminating a porous reinforcement membrane and an electrolyte membrane and transporting the laminated membrane to a first heat roll; a process of blowing high temperature air to 10% to 50% area of a center in a width direction of the laminated membrane before the laminate membrane comes into contact with the first heat roll; and a process of pressing the laminated membrane while heating it by using the first heat roll and the second heat roll, and impregnating the electrolyte membrane into the porous reinforced membrane.SELECTED DRAWING: Figure 3
