Patent number: 7138206Abstract: 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.Type: GrantFiled: June 26, 2002Date of Patent: November 21, 2006Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takashi Yoshida, Kenichi Ishiguro, Yoshitsugu Nishi

Publication number: 20050238941Abstract: 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).Type: ApplicationFiled: August 20, 2003Publication date: October 27, 2005Applicant: Honda Giken Kogyo Kabushiki KaishaInventors: Yoshitsugu Nishi, Kenichi Ishiguro
