Polymer Electrolyte Membranes prepared from 4,4-Bis(4-chlorophenylsulfone)-1,1-biphenyl Compound for Fuel Cells and Their Manufacturing Methods

摘要

The present invention relates to a method for preparing a polymer electrolyte membrane made of 4,4-bis(4-chlorophenylsulfone)-1,1-biphenyl compound for fuel cells. More specifically, as a method for preparing an electrolyte membrane by producing and using a novel membrane, the objective of the present invention is to provide a polymer electrolyte membrane for fuel cells effectively having ion conductivity at low temperatures and to provide materials capable of being sulfonated for an electrolyte membrane for fuel cells. In the polymer electrolyte membrane of the present invention, as the synthesized sulfonated polymers are added hereto with hydrophobic polymers and copolymers, the polymer electrolyte membrane has excellent ion conductivity and high ion conductivity at low temperatures and in high humidity.
