    摘要： The present invention relates to a solid polymer electrolyte membrane having both of a higher proton conductivity and a smaller methanol permeability, which can be produced by conducting a graft polymerization of a fluororesin thin membrane irradiated with a radiation with a monofunctional monomer and again irradiating the resulting film with a radiation, followed by conducting a graft polymerization thereof with a polyfunctional monomer; and a high-performance fuel cell comprising the solid polymer electrolyte membrane, a fuel electrode and an air electrode, said solid polymer electrolyte membrane being disposed between the fuel electrode and the air electrode.

    摘要： Disclosed is a solid polymer electrolyte membrane obtained by graft-polymerizing one or more kinds of radically polymerizable monomers to a resin membrane which is irradiated with radiation. This solid polymer electrolyte membrane is characterized in that at least one kind of the radically polymerizable monomers is a monofunctional monomer having one alkenyl group and a plurality of aromatic rings. By using a monofunctional monomer having one alkenyl group and a plurality of aromatic rings as at least one kind of the radically polymerizable monomers for radiation graft polymerization, there can be obtained a solid polymer electrolyte membrane having good oxidation resistance. When this solid polymer electrolyte membrane is used as an electrolyte membrane of a fuel cell, the fuel cell can have a long life since a grafted polymer chain is hardly decomposed.
