  • Patent number: 7138206
    Abstract: In manufacturing a separator for use in a fuel cell, first, a core (31, 94) is interposed between two preforms (17, 90, 101) and a with-core separator (41, 95, 107) is formed. After this, the core is melted by heating and discharged to form multiple cooling water passages (54). Because consequently there is no need to bring separators together to form the cooling water passages, a seal becomes unnecessary. Also, since there is no need to bring separators together the electrical contact resistance also falls.

  • Publication number: 20060054269
    Abstract: A method for manufacturing a fuel cell separator (18) for sandwiching from both sides via diffusion layers (15, 16) an anode (13) and a cathode (14) disposed on an electrolyte membrane (12). This manufacturing method includes mixing a thermoplastic resin (46) and a conductive material (45) to make a mixture (50), forming a separator starting material (68) with the mixture, and irradiating a contact face (20b, 30b) of this separator starting material with an electron beam (72), hardening the contact face of the separator. Even when reaction heat is produced in the fuel cell (10), elasticity of the separator contact face is ensured.

  • Publication number: 20050238941
    Abstract: Fuel cell separators (18) sandwich an anode (13) and a cathode (14) which are installed along both sides of an electrolyte film (12) and diffusion layers (16, 16). The separators (18) are made of a mixture material containing a thermoplastic resin selected from ethylene-vinyl acetate copolymers and ethylene-ethyl acrylate copolymers and carbon particles selected from at least one of Ketjen black, graphite and acetylene black. Since the thermoplastic resin is excellent in especially flexibility, the contact surfaces of the separators (18) in contact with the diffusion layers (15, 16) can be a portion excellent in sealability by adding the thermo-plastic resin excellent in sealability to the separators (18).
