摘要

Perfluorinated ionomers such as Nafion®, invented by Walter Grot, show excellent stabilities in fuel cells and other electrochemical processes such as in membrane chloralkali electrolysis (1-5). Their main disadvantages are:complicated and environmental-unfriendly production process which involvestoxic intermediates and waste products, high price,strong decrease of proton conductivity when the water content of themembrane is reduced (6,7),
