        Quaternary amonium salts are used as anion-exchange and also easily decomposed due to their intrinsic structural instability. These drawbacks have limited the long-term utilization of the membranes. The objectives of this study are to synthesize high performance anion-exchange membranes and to investigate their electrochemical properties The new membranes were prepared via a monomer sorption method. Their morphological and electrochemical properties have been investigated through various analyses. While the accumulated water-splitting flux of the commercial membrane containing conventional quaternary ammonium groups was shown to largely increase with time, theirs of the new membrane was shown without significant change.
