Embodiment Construction

[0071] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0072] figure 1 is a schematic diagram showing a method for manufacturing a composite electrolyte membrane (electrolyte membrane) of the first embodiment, figure 2 is used to implement figure 1 Schematic representation of the fabrication equipment for the fabrication method shown.

[0073] Such as figure 1 and figure 2 As shown, first, a strip-shaped electrolyte sheet (electrolyte sheet) 11 and a strip-shaped reinforcing sheet 12 composed of polytetrafluoroethylene (PTFE), which is a porous polymer material, are prepared and laminated. More specifically, in the lamination process, the electrolyte sheet 11 and the reinforcement sheet 12 are heated and laminated to produce a laminate 10A in which the electrolyte sheet serves as the electrolyte layer 11a and the reinforcement sheet 12 serves as the reinforcement layer 12a.

Abstract

A method for manufacturing a composite electrolyte membrane including: a first folding process of folding a laminate (10A) obtained by laminating and integrating an electrolyte sheet (11) having an electrolyte as an electrolyte layer and a reinforcing sheet (12) having a porous polymer material as a reinforcing layer, so that a part of a surface of the laminate (10A) lies on another part of the surface; an impregnation process of impregnating the electrolyte of the folded laminate (10B) into the reinforcing layer; and a hydrolysis process of hydrolyzing the electrolyte impregnated in the laminate (10C).

Description

technical field [0001] The present invention relates to composite electrolyte membranes, membrane electrode assemblies, fuel cells and methods for their manufacture, and more particularly to composite electrolyte membranes having at least an electrolyte layer composed of an electrolyte and a reinforcement layer in which a porous polymer material is impregnated with the electrolyte Type electrolyte membrane, membrane electrode assembly, fuel cell and methods for manufacturing them. Background technique [0002] A solid polymer type fuel cell using an electrolyte membrane has been studied for application to a movable body such as an automobile because it operates at a low temperature and has a small size and weight. In particular, social interest in fuel cell vehicles mounted with solid polymer type fuel cells as eco-friendly vehicles is growing. [0003] Such as Figure 14 As shown, the solid polymer fuel cell has a membrane electrode assembly (MEA) 95 as the main structural...
