Abstract

Official abstract text for this publication.

A method for manufacturing an integrated sheet of a MEGA and a resin frame, capable of curing a UV curable adhesive in a short time by suppressing an inhibition of curing of the UV curable adhesive and thereby providing excellent productivity is provided. A manufacturing method for an integrated sheet in which a resin frame is bonded to a MEGA, includes preparing a laminate in which a gas diffusion layer is laminated on at least one surface of a MEA, applying a coating of an UV curable adhesive to the laminate; placing a resin frame on the UV curable adhesive and applying a pressure to the frame, and irradiating the UV curable adhesive with ultraviolet rays, in which the irradiating includes a first irradiation step, and a second irradiation step in which ultraviolet rays are applied with irradiation intensity higher than irradiation intensity in the first irradiation step.

First claim

Opening claim text (preview).

What is claimed is: 1 . A manufacturing method for an integrated sheet in which a resin frame is bonded to a membrane electrode gas diffusion layer assembly (MEGA), comprising: preparing a laminate in which a gas diffusion layer is laminated on at least one surface of a membrane electrode assembly; applying a coating of an ultraviolet (UV) curable adhesive to the laminate; placing a resin frame on the UV curable adhesive and applying a pressure to the resin frame; and irradiating the UV curable adhesive with ultraviolet rays, wherein the irradiating includes a first irradiation step, and a second irradiation step in which ultraviolet rays are applied with irradiation intensity higher than irradiation intensity in the first irradiation step. 2 . The manufacturing method for an integrated sheet according to claim 1 , wherein the second irradiation step is started after the first irradiation step is started and before a temperature of the resin frame reaches a temperature at which radical quenching occurs.
