Quasielastic neutron scattering was used to study the atomistic proton diffusion mechanism in Yb-doped SrCeO3, a proton conducting perovskite, simultaneously in space and time. Proton diffusion consists of a sequence of trapping and free diffusion events. The free diffusion corresponds to the Grotthus mechanism including very fast rotations around oxygen ions.
