  • Patent number: 10680269
    Abstract: The invention relates to a fuel cell stack having at least two segments of individual fuel cells arranged in parallel in terms of fluid, said segments being arranged in series relative to one another in terms of fluid. It is provided that the fuel cell stack is set up to vary the number of individual fuel cells in at least one segment.
    Type: Grant

  • Patent number: 10665871
    Abstract: The invention relates to a fuel cell stack having bipolar plates (10), each of which has two separator plates (12, 14) with an active region (16) and two distribution regions (18, 20) with main gas ports (22, 24) as well as a coolant main port (26), wherein the separator plates (12, 14) are formed and arranged one over the other in such a way that the respective bipolar plate (10) has separate channels (28, 30, 32) for the reaction gases and the coolant that connect the main gas port (22, 24) for the reaction gases and the coolant main port (26) of the two distribution region (18, 20) to each other. It is provided that the channels (28) for a reaction gas have an impermeable first dividing plate (38) in an inlet area (40) of the active area (16) that separates the channels (28) into two volume areas (58, 60), and in that a second main gas port (23) is provided adjacent to the first main gas port (22) in a distribution region (18) in order to supply the reaction gas.

  • Patent number: 10483563
    Abstract: A cathode supply (30) for a fuel cell (10) of a fuel cell unit (1) for a fuel cell system is provided, the cathode supply (30) including a cathode supply path (31) and a cathode exhaust gas path (32) and at least two fluid pumping devices (33, 133) for pumping a cathode operating medium (5) for the fuel cell (10) are fluido-mechanically coupled into the cathode supply path (31), at least one first fluid pumping device (133) of the at least two fluid pumping devices (33, 133) being drivable only on the basis of an enthalpy in a cathode exhaust gas (6) of the fuel cell (10). A fuel cell unit for a vehicle, in particular, an electric vehicle, a fuel cell system for a vehicle, in particular, an electric vehicle, or a vehicle in particular an electric vehicle, the fuel cell unit, the fuel cell system, or the vehicle including a cathode supply (30) is provided.

  • Publication number: 20170222235
    Abstract: A humidifier, a device including a fuel cell, and a motor vehicle. The humidifier of the includes at least one humidifying duct and is designed in such a way that a first gas to be humidified can be conducted in the humidifying duct in a direction of flow and, separated by a water-permeable material, past a humidifying second gas so that water is transferred from the second gas to the first gas. The humidifier includes a cross-sectional area of the humidifying duct available to the first gas tapers in the direction of flow. The fact that the cross-sectional area tapers results in a drop in pressure along the humidifying duct, and the drop in pressure reduces, compensates or overcompensates an increase in pressure resulting from the increasing humidification, so the partial difference in pressure between the first gas and the second gas remains large over the distance of the humidifying duct in spite of the transfer of humidity.
