  • Patent number: 7951500
    Abstract: In one embodiment the present invention provides for an anode side gas flow heater for a fuel cell generator that comprises a recirculating anode gas flow 28, at least one burner 24, and an energy source 22. The energy source heats the burner, the anode gas flow passes over the at least one burner and is heated, and the heated anode gas flow is then passed through the anode side of the fuel cell generator 4, where the fuel cell generator is heated.

  • Patent number: 7947408
    Abstract: The collecting plate of the present invention is used in a stacked fuel cell, and comprises a collecting section and an output terminal that is electrically connected to the collecting section and has a thickness that is greater than the thickness of the collecting section. For example, the output terminal is formed by bending at least part of an output terminal forming portion that is extended from the collecting section, at least one time.

  • Patent number: 7939197
    Abstract: An electrode plate of a rechargeable battery that is capable of preventing wastage of a base film and preventing an active material layer from being irregularly formed and a method for fabricating the same is disclosed. The electrode plate is fabricated by continuously coating the active material layer lengthwise along a surface of the base film and cutting the base film in a direction substantially perpendicular to a length of the base film or in a direction that forms a predetermined angle in relation to the length of the base film. The method includes forming an active material layer lengthwise on a base film except for on predetermined parts of both ends of the base film by continuously coating active materials, and forming an electrode plate by cutting the base film formed with the active material layer in a direction substantially perpendicular to the length of the base film using a cutter.

  • Patent number: 7914921
    Abstract: The present invention discloses enhanced separators for storage batteries with zinc negative electrodes. These enhanced separators include a separator layer and one or more resistive layers on said separator layer. The dimensions of the one or more resistive layers are less than or equal to that of the separator layer. Portions of the separator layer can also be treated with a PTFE suspension to increase the resistance at those portions. For storage batteries where the resistance along two edges of the separator layer has to be larger then the center, the enhanced separator include said resistive layers where each layer includes two independent parts positioned along the two edges of the separator layer. The edge portions of the separator layer can also be treated with a PTFE suspension. Using these enhanced separators in storage batteries with zinc negative electrodes can increase the capacity and prolong the life of the batteries.

  • Patent number: 7909893
    Abstract: The invention relates to a lithium battery, comprising at least one lithium intercalation compound, made up of crystallites and obtained by a production method, comprising at least the following steps: formation of a homogeneous mixture of at least one precursor for the lithium intercalation compound with a given adjunct, chemically stable with relation to crystallites and designed to limit the growth of crystallites or crystallite precursors during the formation thereof, thermal treatment of the homogeneous mixture for the synthesis of the lithium intercalation compound in the form of crystallites and to give a composite material comprising at least two phases formed respectively by the lithium intercalation compound and the adjunct and forming of the composite material to give said electrode. The invention further relates to an electrode obtained by said method and lithium battery comprising such an electrode.
