  • Cathode flow fuel cell systems and manifolds with an add-on stiffener
    Patent number: 11011772
    Abstract: A fuel cell system includes a fuel cell stack including a plurality of fuel cells positioned between opposing end plates, an anode manifold configured to direct anode gas into or out of the fuel cell stack, a cathode manifold configured to direct cathode gas into or out of the fuel cell stack, and at least one truss attached to an external surface of at least one of the cathode manifold or the anode manifold. The at least one truss is configured to reinforce the fuel cell system.

  • Gasket for fuel cell system manifold seal
    Patent number: 9005837
    Abstract: A gasket for a manifold seal for a fuel cell system includes a first layer of fibrous ceramic material having a first compressibility, a second layer of fibrous ceramic material having a second compressibility and a third layer of fibrous ceramic material having third compressibility. The third layer of fibrous ceramic material is positioned between and engaged with the first layer of fibrous ceramic material and the second layer of fibrous ceramic material. The third compressibility is less than the first compressibility and less than the second compressibility.

  • Manifold assembly for controlling gas flow and flow distribution in a fuel cell stack
    Patent number: 8911914
    Abstract: A manifold assembly for use with a fuel cell stack for the purpose of ensuring a desired flow distribution to fuel cells within the stack, with the most commonly desired being uniform flow distribution. Said manifold assembly comprising: an external manifold for abutting and sealingly enclosing a face of the fuel cell stack, wherein the manifold comprises an enclosure for one of: providing inlet gas to the fuel cell stack and receiving exhaust gas from said fuel cell stack; and one or more baffles disposed in the enclosure of the external manifold, the one or more baffles one of: (a) controlling gas flow distribution and direction of the inlet gas from the enclosure to fuel cells of the fuel cell stack to achieve a predetermined distribution or a uniform distribution; and (b) controlling gas flow distribution of the exhaust gas flow within the enclosure to achieve the predetermined distribution or the uniform distribution of gas to fuel cells of the fuel cell stack.
