  • Method and apparatus for supplying input gases to a fuel cell stack
    Patent number: 8481217
    Abstract: A fuel supply system for a fuel cell stack includes a cathode gas supply line for supplying an oxidant to the cathode input of the fuel cell stack and an anode gas supply line for supplying fuel to the anode input of the fuel cell stack. An anode gas recirculation line recirculates partially used anode gas from the anode output to the anode input while a purge line may be connected for conducting away the partially used anode gas, as a purge gas from the anode gas recirculation line into the cathode gas supply line. The supply system also includes a conditioning arrangement disposed upstream of the cathode input. The conditioning arrangement is designed to a) mix a partial flow of the oxidant with the purge gas in a mixing station, b) compress accelerate, and/or heat the partial flow or the mixed flow, and c) conduct the mixed flow into the cathode gas supply line.

  • Method of operating a particle filter in the exhaust system of a motor vehicle's internal combustion engine
    Patent number: 8474246
    Abstract: In a method of operating a particle filter in an exhaust system of a motor vehicle internal combustion engine, wherein the particle filter is reconditioned, in intervals, by a soot-burn-off procedure, the amount of noncombustible ashes also collected in the particle filter is reduced by heating the particle filter and supplying to the particle filter, together with the exhaust gas of the internal combustion engine, a reducing agent which reacts with the ash deposits so as to chemically convert the ash deposits such that at least non-metallic ash components are decomposed and carried out of the particle filter by the exhaust gas.

  • STABLE, DURABLE CARBON SUPPORTED CATALYST COMPOSITION FOR FUEL CELL
    Publication number: 20130164655
    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.

  • Urea tank with closure member for vehicle exhaust system
    Patent number: 8459013
    Abstract: A closure member for a urea tank used to provide urea to an exhaust treatment system of a vehicle comprises a closure member body defining respective urea inlet and outlet passages and coolant inlet and outlet passages therethrough. A valve carried by the closure member body, and a portion of the valve can be an integral one piece part of the closure member body, selectively blocks the flow coolant through the interior of the urea tank. When coolant flows into the tank, it is separated from urea in the tank by a recirculating conduit which returns the coolant from the coolant inlet passage to the coolant outlet passage. Coolant circulating within the tank heats urea therein. The coolant flow valve can comprise a solenoid controlled valve with an electrical connector carried by the coolant tank for making connections to wiring that provides power to the solenoid to control the valve.
