Abstract: A carbon supported catalyst composition for solid polymer electrolyte fuel cells is disclosed that shows a high mass activity and favorable stability and durability. The catalyst composition comprises an intermetallic phase or alloy comprising Pt and a metal selected from the group consisting of Nb, Ta, V and Mo, and comprises an oxide of the metal. The carbon supported catalyst composition can be prepared at relatively low temperature either by first depositing and heating an oxide precursor of the metal on a suitable carbon to make a hybrid support, and then depositing and heating a Pt precursor on the hybrid support, or by depositing both an oxide precursor of the metal and a Pt precursor on a suitable carbon support, and directly heating to a final temperature.

Abstract: A seat belt for a vehicle includes a belt webbing with several belt webbing layers and, in a shoulder belt region and a lap belt region, a belt interior located between at least two belt webbing layers to which a gas can be applied. The belt webbing is routed through an opening of a latch plate which is insertable into a buckle, by means of which latch plate the belt webbing is, if the seat belt is fastened, deflected at a lower deflection point in a transitional region from the lap belt region to the shoulder belt region. A gas passage connecting at least two sections of the belt interior is provided at the lower deflection point between the at least two belt webbing layers. The gas passage is a tube that is flexible at least in the radial direction. The flexible tube is plastically or elastically deformable.

Abstract: An engine is coupled to an input member of a hybrid transmission and the hybrid transmission is operative to transfer torque between the input member and a torque machine and an output member to generate an output torque in response to an operator torque request. The torque machine is connected to an energy storage device. A method for controlling the engine includes determining a preferred input torque from the engine to the hybrid transmission based upon operator inputs to an accelerator pedal and a brake pedal, determining maximum and minimum allowable input torques from the engine to the hybrid transmission, controlling the engine at the preferred input torque when the preferred input torque is within the maximum and minimum allowable input torques, and controlling the engine based upon the maximum and minimum allowable input torques when the preferred input torque is outside one of the maximum and minimum allowable input torques.
