Manufacturing method of fuel cell assembly

Abstract

A method for manufacturing a fuel cell assembly includes: arranging an end face of a gas diffusion layer on a placement jig in a state abutting an end face of a resin frame; melting a part of the frame member and causing to penetrate into the gas diffusion layer by pressurizing the projecting part by way of a heat-transfer member, and heating the projecting part via the heat-transfer member by abutting a heating member against of the heat-transfer member; and solidifying the part of the resin frame having penetrated into the gas diffusion layer, in which an abutting position of the heating member relative to the heat transfer member is set in the melting step so that a central axis of the heating member is positioned more to a side of the gas diffusion layer than the central axis of the projecting part.

Description

technical field

[0001] The present invention relates to a method of manufacturing a fuel cell assembly obtained by joining an electrolyte membrane-electrode assembly having an electrode including a porous member to obtain a fuel cell assembly. Background technique

[0002] Conventionally, a technique related to a method of manufacturing a fuel cell assembly in which a resin frame is joined to an MEA (Membrane Electrode Assembly) is known. As a document disclosing such a technique, there is Patent Document 1, for example. Patent Document 1 discloses a technique for manufacturing a bonding material including a step of forming a butting portion by placing edge portions of a porous member and a resin member against each other on a placing jig, passing a heat transfer member In the process of pressing the abutting portion and the process of bringing the heating member into contact with the heat transfer member pressing the abutting portion, in this manufacturing method, a protru...
