PROTON-CONDUCTING POLYMER MEMBRANE CONTAINING POLYMERS WITH SULFONIC ACID GROUPS THAT ARE COVALENTLY BONDED TO AROMATIC GROUPS, MEMBRANE ELECTRODE UNIT, AND USE THEREOF IN FUEL CELLS

摘要

Disclosed is a proton-conducting polymer membrane containing polymers with sulfonic acid groups that are covalently bonded to aromatic groups and polymers which comprise phosphonic acid groups and are obtained by polymerizing monomers encompassing phosphonic acid groups.
