Abstract
Official abstract text for this publication.
A fuel cell comprises a membrane electrode assembly configured such that electrode catalyst layers are formed on respective surfaces of an electrolyte membrane; gas diffusion layers placed on respective surfaces of the membrane electrode assembly; and a frame placed around periphery of the membrane electrode assembly. The membrane electrode assembly has a protruding portion that is configured by protruding outside of the gas diffusion layer in a state that the membrane electrode assembly is combined with the gas diffusion layers. The frame has an engagement portion that is configured to engage with the protruding portion. An adhesive layer is formed from an ultraviolet curable adhesive between the protruding portion and the engagement portion.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fuel cell, comprising: a membrane electrode assembly configured such that electrode catalyst layers are formed on respective surfaces of an electrolyte membrane; gas diffusion layers placed on respective surfaces of the membrane electrode assembly; and a frame placed around periphery of the membrane electrode assembly, wherein the membrane electrode assembly has a protruding portion that protrudes outside of an outer edge of one of the gas diffusion layers when the membrane electrode assembly is combined with the gas diffusion layers, the frame has an engagement portion that is configured to engage with the protruding portion outside of the outer edge of one of the gas diffusion layers, and wherein the fuel cell further comprises an adhesive layer formed from an ultraviolet curable adhesive between the protruding portion and the engagement portion, wherein the engagement portion of the frame includes a through hole that is formed to pass through the frame in a thickness direction of the frame; wherein the through hole exposes the adhesive in the area of the engagement portion. 2. The fuel cell according to claim 1 , wherein the ultraviolet curable adhesive forming the adhesive layer further contains a heat hardener prior to curing of the adhesive layer. 3. The fuel cell according to claim 1 , wherein the frame is formed from a thermoplastic resin.
