with ytterbium and water, e.g. SrCe0 95Yb005 H0 02O2 985, is a well known proton conductor at elevated temperatures. We have studied its proton conductivity or diffusivity, respectively, by impedance spectroscopy, IS, and by quasielastic neutron scattering, QENS. While the former method yields a macroscopic proton diffusion coefficient, the latter method allows to elucidate the microscopic proton diffusion mechanism. It consists of a se­ quence of free diffusion and trapping/escape events with the Yb3 + ions acting as trapping centers. The self
