SOLID POLYELECTROLYTE MEMBRANE, PROCESS FOR PRODUCTION THEREOF, AND FUEL CELLS

摘要

A solid polyelectrolyte membrane is obtained by grafting a dense fluororesin membrane having a thickness of 10 to 50mum with a polymerizable monomer by irradiation with an electron beam accelerated in vacuum at an acceleration voltage of 60 to 300kV through an electron permeable window in an inert gas atmosphere in an absorbed dose of the membrane of 1 to 50kGy. A fuel cell is produced by setting the solid polyelectrolyte membrane between a fuel electrode and an air electrode. ® KIPO & WIPO 2008
