Abstract:
Provision of, and a method for production of, a polymer electrolyte membrane, which is characterized by introducing a vinyl monomer into an aromatic polymer membrane substrate, typified by polyether ether ketone, polyether imide, or polysulfone, as graft chains by graft polymerization, and then chemically converting some of the graft chains or/and part of the aromatic polymer chain into sulfonic groups.
