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.

First claim

What is claimed is:

1. A method for manufacturing a fuel cell assembly that is obtained by joining a resin member and a membrane electrode assembly having an electrode containing a porous member, the method comprising the steps of:
arranging an end face of the porous member on a placement jig in a state abutting an end face of the resin member having a projecting part formed along the end face thereof;
melting a part of the resin member and causing to penetrate into the porous member 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 at an opposite side to a side contacting the projecting part of the heat-transfer member; and
solidifying the part of the resin member having penetrated into the porous member,
wherein an abutting position of the heating member relative to the heat-transfer member is set in the melting step so that a center of an abutting part in contact with the heat-transfer member of the heating member is positioned more to a side of the porous member than a center of the projecting part.

2. A method for manufacturing a fuel cell assembly according to claim 1 ,
wherein a capturing recessed part is formed on an opposite side of the projecting part to the porous member in the resin member, and
wherein the heat-transfer member is formed in a size so that a contact face thereof with the resin member can seal the capturing recessed part in the melting step.

3. A method for manufacturing a fuel cell assembly according to claim 1 ,
wherein the center of the abutting part in contact with the heat-transfer member of the heating member has the highest temperature, in relation to temperature of the heat-transfer member.

4. A method for manufacturing a fuel cell assembly according to claim 1 ,
wherein the center of the abutting part in contact with the heat-transfer member of the heating member is positioned more to a side of the porous member than the abutting part in contact with the heat-transfer member of the projecting part.
