Brønsted acid–base ionic liquids and their use as new materials for anhydrous proton conductors

Abstract

Novel Brønsted acid–base ionic liquids, derived from a simple combination of a wide variety of organic amines with bis(trifluoromethanesulfonyl) amide are electroactive for H₂ oxidation and O₂ reduction at a Pt electrode under non-humidifying conditions, which shows the prospect of the use of protic ionic liquids as new materials for anhydrous proton conductors at elevated temperatures.
