SOLE POLYELECTROLYTE FILM AND PROCESS FOR PRODUCING SAME, AND FUEL CELL

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 mum 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.
