摘要： In the present invention, a solid polyelectrolyte film is obtained by irradiating a dense fluorinated resin film having a thickness of 10 to 50 μm in an inert gas atmosphere with an electron beam having been accelerated at an accelerating voltage of 60 to 300 kV in vacuum and transmitted through an electron beam-transmitting window so that an absorbed dose is from 1 to 50 kGy, followed by graft-polymerizing a polymerizable monomer. Moreover, the solid polyelectrolyte film is disposed between a fuel electrode and an air electrode to form a fuel cell.

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.
