  • Publication number: 20120091403
    Abstract: The preparation of a slurry so as to exhibit no strong alkalinity not only needs a strict pH control, but also needs once dispersing a positive electrode material in water and the operation of drying after the treatment, and other operations, thereby leading to the complication of the operations and a decrease in the yield. In consideration of the above-mentioned problems, the present invention provides a method for producing a positive electrode plate for a lithium ion rechargeable battery, which exhibits less complication of the operations and less decrease in the yield and can prevent the gelation of a positive electrode material slurry. The above-mentioned problems can be solved by a positive electrode for a lithium ion rechargeable battery containing a positive electrode active material capable of absorbing/desorbing lithium ions, a nitrile group-containing polymer, and a binder.

  • Patent number: 7727649
    Abstract: A polymer electrolyte fuel cell comprises a fuel cell stack and a humidifier. The fuel cell stack includes plural cells in which each cell has a pair of electrodes and a proton-conductive electrolyte membrane arranged between the pair of electrodes, wherein an oxidant gas or a fuel gas passes through the humidifier before being fed to the fuel cell stack, and wherein a wet gas containing water or water vapor also passes through the humidifier. In the fuel cell, the humidifier includes a porous separating layer and a hydrophilic water-releasing layer, wherein the separating layer is configured to separate the wet gas from the oxidant gas or the fuel gas in the humidifier, and wherein the hydrophilic water-releasing layer is disposed in a side of the oxidant gas or the fuel gas to the separating layer in the humidifier.
