  • Stack of cells of a fuel cell and fuel cell comprising such a stack
    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.
