Abstract

In a method for manufacturing a resin-framed membrane electrode assembly for a fuel cell, a membrane electrode assembly structure is held between a first framed diffusion layer and a second framed diffusion layer while the membrane electrode assembly structure is housed in a recess provided in at least one of a first resin frame component and a second resin frame component. The first resin frame component and the second resin frame component are joined to each other to integrate the first framed diffusion layer and the second framed diffusion layer. The first and second resin frame components are located outside an outer peripheral portion of the membrane electrode assembly structure.

First claim

What is claimed is:

1. A method for manufacturing a resin-framed membrane electrode assembly for a fuel cell, the method comprising:
attaching a first catalyst layer of a first electrode on a first surface of a solid polymer electrolyte membrane;
attaching a second catalyst layer of a second electrode on a second surface of the solid polymer electrolyte membrane to form a membrane electrode assembly structure including the solid polymer electrolyte membrane and the first and sec…
