Abstract: A novel monomer of bisphenol containing dicyanoarylene group was synthesized and followed by copolymerization with activated dihalides to give a series of sulfonated poly(arylene ether nitrile ketone)s with a high molecular weight. The structures of the copolymers were characterized by 1H NMR and elemental analysis. The acid-form membranes of the copolymers exhibited an excellent thermostability, good proton conducti-vity, dimensional and chemical stabilities as well as superior mechanical strength demonstrated by the corresponding technologies available. Which denomstrate the membranes prepared are promising candidate for PEMFC application.

Key words: Fuel cell, Proton exchange membrane(PEM), Poly(arylene ether nitrile)s, Ionomer
