    Abstract: The present invention discloses a preparation method of an alkaline anion exchange membrane and a use of the membrane in a fuel cell. The preparation method of the alkaline anion exchange membrane contains: taking polyvinyl alcohol as a substrate, which provides mechanical strength for the membrane; taking a commercialized alkaline resin as an anion exchange resin of chemically reactive groups, performing a cross-linking reaction between polyvinyl alcohol and the alkaline resin by mixing; meanwhile, during the process of forming the alkaline anion exchange membrane, adding an organic salt of transition metal, and doping transition metal ions into the membrane. By taking advantages of catalytic characteristics of the transition metal ions, the fuel leaking from the anode of the cell can perform a catalytic reaction in time in the ion exchange membrane, and thereby improve an ion conductivity of the membrane and efficiently decrease a resistance of the cell. The fuel cell assembled by the anion exchange membrane prepared in the present invention shows an excellent power-generating property.

    Abstract: A catalyst layer for a fuel cell includes a catalyst-supporting carbon in which a catalyst is supported on carbon support powder of which particles have pores, a first electrolyte resin having an oxygen permeability of less than 2.2×10−14 mol/(m·s·Pa) under an environment at a temperature of 80° C. and a relative humidity of 30%, and a second electrolyte resin having an oxygen permeability of 2.2×10−14 mol/(m·s·Pa) or more under an environment at a temperature of 80° C. and a relative humidity of 30%. The content of the first electrolyte resin is an amount equal to or larger than a value X [g] obtained in the equation X=S×R/4436 with respect to 1 g of the carbon support. S denotes a surface area [m2] of the carbon support. R denotes a proportion of the area of the outermost surface of the carbon support with respect to the surface area of the carbon support.
