ABSTRACT:
A proton conductive membrane displays sufficient proton conductivity even at low humidities and low temperatures.The proton conductive membrane includes:a block copolymer including an ion conductive polymer segment (A) and an ion nonconductive polymer segment (B), the segment (A) and the segment (B) being covalently bound in a manner such that main chain skeletons of the segments are covalently bound at aromatic rings thereof through binding groups,(i) the membrane having a morphology including a microphase separated structure,(ii) the ion conductive polymer segment (A) forming a continuous phase.
