Tetrazole-based, anhydrous proton exchange membranes for fuel cells

Abstract

A tetrazole-based polymer electrolyte membrane showed high conductivity at 20-120°C under dry conditions, offering the potential to dramatically simplify fuel cells for many applications over a wide temperature range without the need for cumbersome humidification and pressurization.

Keywords: anhydrous proton conduction; fuel cells; low humidity; polymer membranes; tetrazoles.
