The field of ionic liquids is one of the hottest topics with the number of publications still growing exponentially. This is due to the negligible vapour pressure, non-flammability, wide liquid, solubility and miscibility range of most ionic liquids. Ionic liquids have been often described as designer solvents, as properties of their ions can be changed to improve the suitability for a given process. Protonated ionic liquids are excellent proton carriers in fuel cell electrolytes, providing electrolytes of a type that are simply not available in systems in which water acts as acid or base in the proton transfer process. But, there is a lacuna in our knowledge of these compounds. Utilisation of beam time at ISIS will help us to shed light on proton behaviour processes of protonated ionic liquids.
