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

摘要

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 adherend, such as an electrolyte membrane, 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 substrate, 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 an adherend after the adhesion of the reinforcing material to the adherend, and it also becomes possible to prevent the formation of wrinkles on the adherend or the like upon the adhesion of the reinforcing material. In this manner, a catalyst layer laminated membrane or the like which has a reinforcing material attached thereto can be produced readily without requiring the employment of any highly skilled technique.
