  • Patent number: 10276881
    Abstract: The invention relates to a stack of cells of a fuel cell comprising an anode plate and a cathode plate, at a first one of the two ends thereof, the stack ending in a first anode or cathode end plate, respectively, arranged on the cathode or anode plate, respectively, of the last cell of the stack, said first end plate defining a circuit for the cooling fluid of the last cell and said first end plate being an anode or cathode plate, respectively, identical to the anode and cathode plates, respectively, of the cells but missing the opening for dispensing reagent. It is thus possible to simplify the development and the assembly of a stack of cells of a fuel cell with proton-exchange membrane while ensuring a good seal and satisfactory cooling at the end of the stack.

  • Patent number: 9601786
    Abstract: Leakproofing device for a fuel cell intended to be interposed between an Electrodes Membrane Assembly and a polar or bipolar plate of a fuel cell unit, the device consisting of a rigid frame and of a leakproofing seal integral with the frame, the frame furnished with the leakproofing seal defining a plurality of apertures through the device, the apertures being delimited by the leakproofing seal.

  • Patent number: 9425467
    Abstract: A fuel cell plate includes at least one circulation channel for a reagent. The at least one circulation channel has an inlet communicating with a reagent distribution orifice formed through the plate. The plate also includes a reagent inlet collector orifice that is distinct from the reagent distribution orifice.

  • Publication number: 20140120449
    Abstract: Fuel cell plate, the reactive face of the plate being provided with reliefs and hollows forming at least one circulation channel for a reagent, the at least one circulation channel for a reagent having an inlet communicating with a reagent distribution orifice formed through the plate, the plate also comprising a reagent inlet collector orifice that is distinct from the reagent distribution orifice, the reagent inlet collector orifice being provided to supply reagent to the inlet of at least one channel via a passage putting in fluid relationship the inlet collector orifice and the reagent distribution orifice, the inlet collector orifice extending longitudinally in the plane of the plate in a first longitudinal direction between a first bottom end and a second top end, the distribution orifice extending longitudinally in the plane of the plate in a second longitudinal direction between a first bottom end and a second top end, the first and second longitudinal directions being parallel to each other and verti
