  • Optimized thermal management fuel cell
    Publication number: 20040170879
    Abstract: A fuel cell comprises a thermal dissipation structure whose connecting element (8) is a shape memory alloy highly conductive at high temperatures, but much less so at low temperatures, which allows the cell to heat up quicker and reach its performance level.

    Inventors: Jean-Yves Laurent, Didier Marsacq, Francis Ternay, Francois De Crecy
  • Fuel cell for powering electronic appliances, in particular portable objects
    Publication number: 20040067396
    Abstract: The fuel cell (2) is of the kind comprising an anode (12) and a cathode (10) between which an electrolyte (18) is interposed. Solid bodies (20) storing a hydrogen mass, able to be decomposed by combustion, are associated to pyrotechnic means (24,26) to release the hydrogen and bring it into contact with the anode (12). Means (38) tap the ambient air to bring it into contact with the cathode (10). Firing of the pyrotechnic means (24,26) is placed under the control of addressing means (28) embedded in the appliance (2). The surplus water produced by the exchange between the hydrogen and the oxygen is resorbed by the temperature increase induced by combustion of the bodies (20). The solid bodies (20) are supported by an interchangeable card (22).

  • Process for making a fuel cell with cylindrical geometry
    Publication number: 20030021890
    Abstract: The invention relates to a process for production of an electrode-membrane-electrode assembly on a cylindrical substrate (1), characterized in that the electrode-membrane-electrode assembly is made by successively depositing an electrode layer (2, 3), a membrane layer (4) and an electrode layer (5, 6) around the said cylindrical substrate, the said substrate being composed of a material that can be totally or partially eliminated during an elimination step at the end of the said process.
