A novel brnsted Acid-base system as Anhydrous proton Conductors for Fuel Cell Electrolytes

摘要

A super-strong acid,bis(trifluoromethanesulfonyl)amide,was combined with 4,4'-trimethylenedipyridine at various molar ratios to prepare a novel series of Brnsted acid-base ionic liquids.The protic neutral salt was electroactive for H_2 oxidation and O_2 reductin at a platinum electrode under non-humidifying condition,which shows the potential of pyridinal systems as new fuel cell electrolytes for elevated temperature operation and foretells the polymeric model of solid-state anhydrous proton conductors.
