Fundamental Studies on the Dynamics and Energetics of Protic Ionic Liquids, and Some Applications to Fuel Cells
Abstract
In the past three years of this project we have sought to understand the nature of the proton in highly conducting protic ionic liquids of types ranging from the neutral to the superacidic. The primary motivation has been to find how to set the proton free to migrate without coupling to other species. In the process we have invented a method of studying the same sample - in the same sealed container - by a sequence of different physical methods, primarily NMR and electrical relaxation, but also admitting Raman and visible spectroscopic probes (see section B.1.1). This new technique, together with the results of other more conventional studies such as viscosity and scanning calorimetry, are to be used to perform a series of critical preparations and measurements, needed to elucidate the behavior of protons in protic ionic liquids.
