From A Fundamental Study on Hydrogen Bond Network and Chain Mobility in Benzimidazole Model Compounds to Various Designs and Development of Benzimidazole-based Anhydrous Membranes for Proton Exchange Membrane Fuel Cell

Abstract

A series of N-containing heterocycles i.e., imidazole and benzimidazole are systematically designed to study how proton transfer in anhydrous system is related to hydrogen bond network and molecular mobility. The work extends to polymers containing heterocycles to clarify the proton conductivity in proton exchange membrane fuel cell (PEMFC).
