Research Abstract

The objective of the research is to evaluate the effect of superacid groups on the properties of aromatic polymers as ion exchange membranes for polymer electrolyte fuel cells(PEFCs). The title polymers were synthesized by Ullmann coupling reaction of iodo- or bromo-substituted poly(arylene ether)s. It was found that the superacid groups significantly improved the hydrophilic/hydrophobic phase separation and proton conductivity of the poly(arylene ether) ionomer membranes. The effect was more pronounced for the block copolymers compared to the homopolymers and random copolymers. The superacid-modified poly(arylene ether) ionomer membranes showed excellent fuel cell performance.
