Title:

REINFORCING MATERIAL FOR SOLID POLYMER FUEL CELL, AND COHESIVE/ADHESIVE COMPOSITION FOR USE IN SAME

Document Type and Number:

WIPO Patent Application WO/2012/141167

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide a reinforcing material equipped with a cohesive/adhesive layer, which has a proper initial adhesion force to an object of interest, such as an electrolytic film, a catalyst layer and a gas diffusion layer, and which can be temporarily fixed readily. A reinforcing material produced by forming a cohesive/adhesive layer on a base, wherein the cohesive/adhesive layer comprises an aliphatic polyamide, an epoxy resin and a polythiol. When the reinforcing material is used, it becomes possible to correct the position of a material of interest after the adhesion of the reinforcing material to the material of interest, and it also becomes possible to prevent the formation of wrinkles on the material of interest or the like upon the adhesion of the reinforcing material. In this manner, a (catalyst layer)-(electrolytic film) laminate or the like which has a reinforcing material attached thereto can be produced readily without requiring the employment of any highly skilled technique.
