  • Publication number: 20240387839
    Abstract: A fuel cell includes (i) a membrane electrode assembly, (ii) a sealing frame surrounding the membrane electrode assembly, (iii) a manifold portion configured to supply and discharge reactant gas, and (iv) bipolar plates arranged on both sides of the membrane electrode assembly and the sealing frame and having a gas distributing structure configured to distribute the reactant gas onto the membrane electrode assembly. The sealing frame has a gas flow channel extending from the manifold portion in a main extension plane of the fuel cell to the gas distributing structure of the bipolar plates. The gas flow channel has a shape with a winding path, at least partially, in the main extension plane. Also disclosed is a corresponding method for manufacturing a fuel cell that is capable of reducing deformation of the sealing frame in the perpendicular direction and avoiding collapse of the gas flow channel, while preventing a significant drop in gas pressure.

  • Patent number: 11630030
    Abstract: A sensor system includes one or more sensors that sense vibrations of a vehicle and one or more processors that can determine a speed of the vehicle and determine whether the vibrations occurring at one or more frequencies of interest (that are based on the speed of the vehicle) indicate damage to a propulsion system of the vehicle. The one or more processors optionally may determine a hunting frequency of a wheel and axle set and/or a lateral acceleration of the wheel and axle set from the vibrations. The one or more processors can determine a conicity of a wheel in the wheel and axle set based on the hunting frequency and/or the lateral acceleration that is determined.

  • Publication number: 20230035126
    Abstract: A fluid control device includes a first conduit having a first end and a second end, and a first fluid that moves within the first conduit between the first end and the second end. The first conduit includes an interior surface defining a cavity of the first conduit. The fluid control device includes a second conduit having a third end and a fourth end, and a second fluid that moves within the second conduit between the third and fourth ends. At least a portion of the second conduit extends within the cavity of the first conduit. The first fluid is separate from the second fluid as the first fluid moves within the first conduit and the second fluid moves within the second conduit.

  • Publication number: 20230016710
    Abstract: A system and method for controlling a vehicle system may determine one or more of a route parameter of a route on which the vehicle system is moving or a vehicle parameter of the vehicle system. The system and method may also determine whether a ratio of a lateral force exerted by one or more wheels of the vehicle system on the route to a vertical force exerted by the one or more wheels of the vehicle system on the route increases to a value exceeding a designated threshold as a result of the one or more route parameter of vehicle parameter that is determined. The ratio of the lateral force to the vertical force exerted by the one or more wheels of the vehicle system on the route may be reduced to a value less than the designated threshold by changing an operation of the vehicle system.
