Polybenzimidazole block sulfonated poly(arylene ether sulfone) ionomers.

Fuel Cells Nanomaterials Center, University of Yamanashi, Kofu, Yamanashi 400-8510, Japan.

Published: August 2011

Novel ionomers based on polybenzimidazole block sulfonated poly(arylene ether sulfone) show excellent thermal properties. The ionic aggregation of sulfonic acid groups leads to well-developed phase separated morphology and thus high proton conductivity at wide humidity range, up to 65 mS cm(-1) at 90% relative humidity.
