    摘要： An apparatus for treating an exhaust gas stream from cold startup through continuous operating conditions of an internal combustion engine includes an oxidizing catalyst bed disposed in an exhaust pipe and a reducing catalyst bed disposed in the exhaust pipe downstream from the oxidizing catalyst bed. The oxidizing catalyst bed has one or more oxidizing catalysts and the reducing catalyst bed has one or more reducing catalysts. A method is provided for treating an exhaust gas stream both during cold start and during continuous operating conditions of an internal combustion engine by passing the stream through an oxidizing catalyst bed having one or more oxidizing catalysts at a light off temperature; a reducing catalyst bed having one or more reducing catalysts and providing hydrogen into the reducing catalyst bed to condition the reducing catalyst; and introducing hydrogen into the internal combustion engine during cold startup.

    摘要： The invention provides devices and techniques for reducing or eliminating fuel crossover from the anode to the cathode in fuel cells using organic fuels. The invention particularly provides proton exchange membranes having passages or channels with or without a catalyst layer active for the electrochemical oxidation of a fuel. The invention reduces fuel crossover by providing void spaces within the membrane where the fuel may be sequestered as it diffuses through the membrane from the anode to the cathode. The sequestered fuel may be removed physically and/or electrochemically. The invention provides for physical removal of the sequestered fuel by means of flowing a gas stream or a liquid stream through the passages thus evacuating the fuel before it diffuses to the cathode. Electrochemical removal of the fuel involves coating the inner walls of the passages with a catalyst, electronically connecting the catalyst with the anode, and electrooxidation of the crossover fuel sequestered in contact with the catalyst which is active for this oxidation process.

    摘要翻译： 本发明提供了用于减少或消除使用有机燃料的燃料电池中从阳极到阴极的燃料交叉的装置和技术。 本发明特别提供了具有或不具有用于燃料的电化学氧化活性的催化剂层的通道或通道的质子交换膜。 本发明通过在膜内提供空隙来减少燃料交叉，其中燃料可以通过膜从阳极扩散到阴极而被隔离。 隔离燃料可以物理和/或电化学去除。 本发明提供了通过使气体流或液体流流过通道从而物理去除隔离燃料，从而在燃料扩散到阴极之前抽空燃料。 燃料的电化学去除包括用催化剂涂覆通道的内壁，将催化剂与阳极电连接，并与与该氧化过程有活性的催化剂相接触的交换燃料电氧化。

    摘要： A bipolar plate comprising a fluid barrier and a sealing frame formed around and overlaping the perimeter of the fluid barrier. The fluid barrier is placed in a mold and then a polymer is injected into the mold, thereby forming the sealing frame around the fluid barrier such that the sealing frame overlaps the perimeter of the fluid barrier. Because there are no surfaces to seal between the perimeter of the fluid barrier and the sealing frame, gaskets or other sealing surfaces are not required. A bipolar plate is further provided comprising a fluid barrier having the perimeter of the fluid barrier between a preformed cathode sealing frame and an anode sealing frame. The anode and cathode sealing frames are adapted to receive an overlapped portion of the perimeter of the fluid barrier. The anode and cathode sealing frames are then bonded together to form a fluid tight seal.

    摘要： An apparatus and method apply water to a hydrogen-containing composition, such as a hydride, in the presence of a catalyst that promotes hydrolysis to generate hydrogen in a controlled manner. The amount of catalyst used can be carefully tailored so that the reaction rate is limited by the amount of catalyst present (passive control) or it can be sufficiently large so that the reaction is controlled by the rate of water addition (active control).

    摘要： Protecting a membrane and electrode assembly in an electrochemical cell having one or more electrocatalysts in intimate contact with the membrane during storage or shipment of the cell. The membrane may be provided in either the non-proton form of a dry or hydrated cation exchange membrane, such as an alkali metal cation form or an ammonium cation form; the wet or dry precursor form of a cation exchange membrane, such as the non-ionically conducting sulfonyl-fluoride polymer membrane; or the dry proton form of a cation exchange membrane. These membrane surfaces are not acidic under open circuit conditions experienced during storage or shipment of the cell. Since some electrocatalysts are degraded during contact with the acidic surface of a hydrated membrane, the non-acidic surface of the membrane protects these electrocatalysts. The method may be used on newly assembled electrochemical cells, on cells being taken out of service, and on membrane and electrode assemblies.
