Considerable research efforts have been devoted to polymer electrolyte membranes fuel cells. It has been recently proposed as a promising approach to replace aqueous electrolytes with protic ionic liquids (PILs). The key property of these systems, setting them apart from conventional ionic liquids, is their proton conductivity. A more thorough understanding of proton transfer mechanisms in PILs, including the determination of a relationship between local microscopic dynamics and macroscopic transport properties, is thus crucial to facilitate the design of applications. The aim of this application is to characterize the local proton transfer mechanism both in the classical and in the quantum frame in the prototype PIL ethylammonium nitrate by means of two complementary neutron scattering techniques, i.e Quasi Elastic Neutron Scattering (QENS) and Deep Inelastic Neutron Scattering (DINS).
