PROTON CONDUCTIVE ELECTROLYTE MEMBRANE AND MANUFACTURING METHOD THEREOF, AND POLYMER ELECTROLYTE FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a proton conductive electrolyte membrane having fully high proton conductivity and fully low methanol permeability; and to provide a method for manufacturing the proton conductive electrolyte membrane, and a polymer electrolyte fuel cell using the proton conductive electrolyte membrane.

SOLUTION: The proton conductive electrolyte membrane allows a plurality of proton conductive polymers to be filled into the pore of a porous film while the plurality of filled proton conductive polymers have different compositions in the thickness direction of the membrane. The method is used to manufacture the proton conductive electrolyte membrane. The polymer electrolyte fuel cell uses the proton conductive electrolyte membrane.
