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.

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

A fuel cell includes an electrolyte electrode assembly, an inner seal member, an outer seal member, a metal separator, and a cell voltage monitor terminal. The electrolyte electrode assembly includes an electrolyte, a pair of electrodes, and a resin frame member. The inner seal member extends around an electrode surface. The outer seal member extends around an outer periphery of the inner seal member. The inner seal member and the outer seal member are disposed on the resin frame member. The cell voltage monitor terminal is embedded in the resin frame member. The cell voltage monitor terminal includes an exposed portion provided between the inner seal member and the outer seal member. The exposed portion is in contact with the metal separator adjacent to the exposed portion.
