摘要： 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.
