    • 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.
    • 在具有一个或多个电催化剂的电化学电池中保护膜和电极组件,在电池的存储或运输期间与膜紧密接触。 膜可以以非质子形式的干或水合阳离子交换膜提供,例如碱金属阳离子形式或铵阳离子形式; 阳离子交换膜的湿或干前体形式,例如非离子导电的磺酰氟聚合物膜; 或阳离子交换膜的干质子形式。 这些膜表面在储存或运输电池过程中经历的开路条件下不是酸性的。 由于一些电催化剂在与水合膜的酸性表面接触期间降解,膜的非酸性表面保护这些电催化剂。 该方法可用于新组装的电化学电池,电池被取出使用,以及膜和电极组件上。

    • A hydrogen-oxygen fuel cell operates with greater safety if a leak develops between the anode and the cathode sides of the fuel cell allowing hydrogen and oxygen to become mixed on whichever side operates at the lower pressure. A recombination catalyst is disposed within the fuel cell to catalyze the recombination reaction of hydrogen and oxygen to form water and prevent the formation of an explosive mixture. The hydrogen-oxygen recombination catalyst is disposed in a hydrogen distribution system, an oxygen distribution system, or a combination thereof. Suitable recombination catalysts include platinum or alloys thereof, palladium, gold, tin, and combinations thereof, with or without platinum. Still other suitable recombination catalysts include, for example, noble metals, nickel-paladium, and nickel oxides. The recombination catalyst may be mixed with a bonding agent, such as polytetrafluoroethylene, so that the recombination catalyst will adhere to surfaces within the hydrogen and oxygen distribution systems.
    • 如果在燃料电池的阳极和阴极侧之间发生泄漏,则氢氧燃料电池操作更安全,允许氢和氧在低压下操作的任何一面混合。 复合催化剂设置在燃料电池内以催化氢和氧的复合反应以形成水并防止形成爆炸性混合物。 氢 - 氢复合催化剂配置在氢分配系统,氧气分配系统或其组合中。 合适的重组催化剂包括铂或其合金,钯,金,锡及其组合,具有或不具有铂。 还有其它合适的重组催化剂包括例如贵金属,镍 - adium和氧化镍。 复合催化剂可以与诸如聚四氟乙烯的粘合剂混合,使得复合催化剂将粘附到氢气和氧气分配系统内的表面。
