  • Resin frame equipped membrane electrode assembly for fuel cell and method of producing the same
    Patent number: 11094947
    Abstract: A resin frame equipped membrane electrode assembly includes an MEA having different sizes of components, and a resin frame member. A resin melt portion is provided for the resin frame member. The inside of a first gas diffusion layer is impregnated with resin as a part of the resin melt portion. A thin portion is provided at an outermost peripheral portion of the resin frame member through a step at an outermost peripheral portion of the resin melt portion, and the thin portion is thinner in a thickness direction than the resin melt portion.
    Type: Grant
    Filed: April 15, 2020
    Date of Patent: August 17, 2021
    Assignee: Honda Motor Co., Ltd.
    Inventors: Suguru Ohmori, Yukihito Tanaka, Yoshihito Kimura, Ryugo Fujitsuka, Shintaro Tanaka, Masaki Tani

  • Fuel cell assembly and method of manufacturing same, and bonding part manufacturing method and device
    Patent number: 9209471
    Abstract: 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.
