Proton donor and acceptor polymer chains under layered-by-layered structure for polymer electrolyte membrane fuel cell (PEMFC)

Abstract

This research focuses on the development of proton conductive performance of polymer membrane for using at high temperature under anhydrous system Heterocyclic molecules such as imidazole and benzimidazole, etc. as a proton conductive species demonstrate the high hydrogen bond interaction with varied number of heterocyclic units. Moreover, the acid functional group plays an important role in providing protons, which have an effect on proton conductive performance. To combine the concepts of proton donor-acceptor with uniform molecular arragement of heterocyclic molecules to enhance proton conductive performance under anhydrous system, the layered-by-layered structure membrane is proposed.
