  • Stable, durable carbon supported catalyst composition for fuel cell
    Patent number: 9040210
    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.

  • Method for operation of a fuel cell system in a vehicle
    Patent number: 9034529
    Abstract: A method of operating a fuel cell system in a vehicle that is switchable to a temporary stop mode and restarted from the stop mode. When, in certain driving situations, it is required to switch to the stop mode, it is then checked whether the operating conditions of the fuel cell system allow a switch to the stop mode. If the switch is allowed it takes place. When a restart of the fuel cell system is required on the basis of the vehicle the settings of the stop mode are cancelled again. The switch to the stop mode involves, with further existing electric contacting of the fuel cell, the air mass flow conveyed by the air conveying device being switched off or reduced to a predefined value and the pressure of the combustion gas supplied being reduced to a predefined value.

  • Turbine for an exhaust gas turbocharger and exhaust gas turbocharger having such a turbine
    Patent number: 9021803
    Abstract: In a turbine for an exhaust gas turbocharger having a turbine housing with a turbine rotor rotatable supported therein and including spiral channels for directing exhaust gas onto the turbine wheel, at least one annular blocking element is supported between the spiral channels and the turbine wheel so as to be rotatable in the peripheral direction of the turbine wheel and additionally movable in the axial direction of the turbine wheel for a controlling the exhaust gas flow to the turbine wheel between impulse turbine mode when extended into the space between the turbine wheel and the spiral chamber and an accumulation made when retracted, with the gas flow through the turbine wheel or by-passing the turbine wheel being adjustable by rotation of the blocking element.

  • Vehicle torque management
    Patent number: 9020726
    Abstract: A torque management system and method is described by which the torque provided by an engine can be controlled based on a mass of the vehicle and, if available, instantaneous and/or predictive slope information. Also, in some modes of operation, torque can be controlled based on speed limit information for upcoming road segments to be traveled by a vehicle. In addition to controlling the maximum allowable torque, optionally the minimum allowable torque can also be controlled to prevent inadvertent decelerations of the vehicle. A driver/operator can optionally override the torque control and the history of override requests can optionally be used to adjust overrides of the system. A plurality of torque control approach sub-methods can be made available with the appropriate sub-mode being selected depending, for example, upon the extent of the available information.
