  • Fuel Cell System Having a Fuel Cell Arranged in a Housing
    Publication number: 20130089800
    Abstract: A fuel cell system includes at least one fuel cell arranged in a housing and an conveyor means for air supply for a cathode region of this fuel cell. A partial air flow branches off from the supply air to the fuel cell after the conveyor, the partial air flow flowing as bearing air and/or cooling air at least through a part of the conveyor. The partial air flow flows in the flow direction before or after the conveyor as scavenging air through the housing of the fuel cell.

  • ASSEMBLING BIPOLAR PLATES FOR FUEL CELLS USING MICROENCAPSULATED ADHESIVES
    Publication number: 20130089809
    Abstract: The flow field plates in a bipolar plate assembly for a fuel cell can be both bonded and sealed appropriately using microencapsulated adhesives. This offers several advantages over using other adhesives which may have limited pot life and/or require lengthy curing periods at elevated temperature during which time the plates must be stably positioned and under compression.

  • Apparatus for humidifying a gas flow
    Patent number: 8408524
    Abstract: In a device for humidifying a gas flow, an atomized liquid is combined with a gas flow in a spray chamber, and passed through a generally U-shaped gas flow passage having a first generally vertical part 3 through which the atomized liquid and gas passes to a lower part 4. From there, the gas passes generally vertically upwardly to an outlet 9. The lower part of the passage incorporates an opening 6 to a water separator 7. The opening 6 is closable by a float device 10, or includes a flow restricting control valve 13.

  • Method for stabilization of optimal input speed in mode for a hybrid powertrain system
    Patent number: 8406970
    Abstract: A method for improving drivability of the powertrain system having an accelerator control includes determining a first transmission input speed having an associated first power loss and operating said transmission using said first transmission input speed. An operational parameter relating to said accelerator control is determined and a second transmission input speed responsive to said operational parameter and having an associated second power loss is determined. The value of at least one of said first and second power loss is biased based on said operational parameter. The first power loss is compared to said second power loss subsequent to the biasing. A third transmission input speed is determined and the transmission is operated using the third transmission input speed.

  • Restraint system with closeable air flow openings
    Patent number: 8403362
    Abstract: A restraint system having support elements can be transferred from a storage position to a restraint position. Flexible casing elements are disposed between the support elements and have air flow openings, such that the support elements having the flexible casing elements enclose a restraint volume in the restraint position. A resistance element is disposed at each of the air flow openings in order to impede or prevent the escape of air from the restraint volume compared to the inflow at the respective air flow opening. Such resistance elements may be formed by a second layer, displaced fabric threads, flexible fabric web sections and other elements such that a check valve function is provided.
