Title:
高分子電解質膜補強用フッ素樹脂コートポリマーフィルム、補強された高分子電解質膜および膜電極組立体
Document Type and Number:
Japanese Patent JP5258310
Kind Code:
B2
Abstract:
Disclosed is a fluororesin-coated polymer film for reinforcing a polymer electrolyte membrane, wherein the fluororesin-coated polymer film is fabricated by forming on at least one side of a polymer film a coating of a reaction product of (A) a fluorine-containing copolymer composed of a fluoroolefin, a cyclohexyl group-containing acrylic ester, and a hydroxyl group-containing vinyl ether, and (B) a crosslinking agent having two or more isocyanate groups. The polymer film according to the present invention not only exhibits sufficiently high initial adhesion strength, with respect to the polymer electrolyte membrane, but also retains thereafter high adhesion strength in actual operating environments.
