Abstract
A polymer electrolyte membrane includes a membrane polymer made of monomer units that have aromatic polyarylenes groups with proton-conducting functional groups bound to the aromatic polyarylene groups. The polymer electrolyte membrane can be used as a proton-conducting polymer membrane between the electrodes in a fuel cell.
