Abstract
Official abstract text for this publication.
A bonded sheet to be applied to a membrane electrode assembly includes gaskets serving as a first sheet member and an electrolyte membrane serving as a second sheet member stacked on the gaskets. The gaskets each include a first bonded portion where grooves provided in a sheet surface direction at least partly face sheet end portions, and a second bonded portion having no groove. The electrolyte membrane is stacked on the gaskets in the first bonded portion and the second bonded portion.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fuel-cell gasket to be stacked on an outer peripheral edge of an electrolyte membrane, the fuel-cell gasket comprising: a sheet-shaped base material, wherein the base material includes a first bonded portion where grooves provided in a sheet surface direction at least partly face an end portion of the base material and a second bonded portion having no groove, and wherein the fuel-cell gasket is stacked on the electrolyte membrane in the first bonded portion and the second bonded portion of the base material. 2. A fuel-cell gasket to be stacked on an outer peripheral edge of an electrolyte membrane, the fuel-cell gasket comprising: a sheet-shaped base material; and an adhesive layer provided on the base material and containing a bonding member, wherein the adhesive layer includes a first bonded portion where grooves provided in a sheet surface direction at least partly face an end portion of the base material and a second bonded portion having no groove, and wherein the fuel-cell gasket is stacked on the electrolyte membrane in the first bonded portion and the second bonded portion of the adhesive layer. 3. A fuel-cell bonded assembly in which the fuel-cell gasket according to claim 1 is stacked on an outer peripheral edge of an electrolyte membrane.
