Fuel cell assembly and method of manufacturing same, and bonding part manufacturing method and device

摘要

The present invention relates to a fuel cell assembly and method of manufacturing same, and a bonding part manufacturing method and device. For instance, in a resin frame, a depression part is subsidence formed from a lower-end face toward an upper-end face, and a housing hole is pass-through formed from a top surface of the depression part toward the upper-end face. For instance, the depression part, a cathode-side electrode and an electrolyte film are housed, and in such a circumstance, an anode-side electrode is housed in the housing hole. A portion of the resin frame permeates a gas diffusion layer which configures the anode-side electrode and is a porous body. Via the permeated site, the resin frame and the gas diffusion layer (anode-side electrode) are integrally bonded.

主权项

1. A method for producing a fuel cell assembly containing a membrane electrode assembly and a resin frame for supporting the membrane electrode assembly, wherein the membrane electrode assembly contains an anode and a cathode with a solid polymer electrolyte membrane interposed therebetween,
the method comprising the steps of: placing the electrolyte membrane and one of the anode and the cathode in a recess, which extends from one surface toward another surface of the resin frame, and placing the other of the anode and the cathode in a housing hole, which is formed as a through-hole that extends from a bottom surface or a ceiling surface of the recess to the other surface; heating a protrusion on an outer surface of the recess or the housing hole to generate a softened material, and pressing the protrusion in order to introduce the softened material into the anode or the cathode; and hardening the softened material, which is introduced into the anode or the cathode, so as to bond the resin frame to the anode or the cathode.
