Abstract
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.

A process for producing a solid polyelectrolyte film by graft-polymerizing a polymerizable monomer onto a resin film which has been irradiated with a radiation, said process comprising 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 in the resin film is from 1 to 50 kGy, followed by graft-polymerizing the polymerizable monomer.
