Title:
HYDROGEN ION-CONDUCTING COPOLYMER INCLUDING A DIPHENYL FLUORENE GROUP IN WHICH A SULFONIC ACID GROUP IS INTRODUCED, METHOD FOR PREPARING SAME, POLYMER ELECTROLYTE MEMBRANE PRODUCED THEREFROM, MEMBRANE/ELECTROLYTE ASSEMBLY USING SAME, AND POLYMER ELECTROLYTE MEMBRANE FUEL CELL ADOPTING SAME
Document Type and Number:
WIPO Patent Application WO/2012/134095
Kind Code:
A3
Abstract:
The present invention relates to a hydrogen ion-conducting copolymer represented by formula 1, to a method for preparing same, to a method for manufacturing a polymer electrolyte membrane made of the hydrogen ion-conducting copolymer, to a membrane/electrolyte assembly using a hydrogen ion-conducting polymer electrolyte membrane produced therefrom, and to a polymer electrolyte membrane fuel cell adopting same. The hydrogen ion-conducting copolymer of the present invention has flexible and strong mechanical properties due to containing a phenylether group and a phenylsulfone group at an appropriate ratio, and also has excellent hydrogen ion conductivity due to containing a diphenyl fluorene group having a sulfonic group introduced therein. Thus, a polymer electrolyte membrane using the hydrogen ion-conducting copolymer has high hydrogen ion conductivity as well as high thermal, mechanical, and dimensional stability.
