Abstract:
The present invention is a grafted polymer electrolyte membrane prepared by first preparing a precursor membrane comprising a polymer which is capable of being graft polymerized, exposing the surface of the precursor membrane to a plasma in an oxidative atmosphere, then graft-polymerizing a side chain polymer to the plasma treated precursor membrane and introducing a proton conductive functional group to the side chain. The resulting grafted polymer electrolyte membrane has excellent stability and performance when used in a proton-exchange membrane fuel cell or for electrolysis of water.
