Electrolyte membrane and its manufacturing method, and a polymer electrolyte fuel cell for a polymer electrolyte fuel cell

2012 
Suppressing swelling shrinkage due hydrous electrolyte membrane for a polymer electrolyte fuel cell, to improve the durability of the electrolyte membrane, and an object thereof to provide an excellent electrolyte membrane power generation characteristics at low resistance. By distributing the configuration nonwoven as a reinforcing layer in the composite fibers 2a of the electrolyte material and PVDF in the electrolyte in the membrane of a polymer electrolyte fuel cell, to improve the durability of the electrolyte membrane. Furthermore, it is possible to effectively water retention generated water by having voids 23 in the composite fibers 2a, to improve the battery performance at low humidity conditions.
