abstract = {We have investigated the diffusion dynamics of protons in
hydrated $4.2\%Ca-doped$ LaPO4, a candidate electrolyte for
proton-conducting intermediate temperaturefuel cells. The
macroscopic and microscopic dynamics have been studied
usingelectrochemical impedance spectroscopy (EIS) and
quasi-elastic neutron scattering(QENS), respectively. The
conductivity of the bulk hydrated sample was determined
inthe temperature range of 500−850 °C by EIS and showed a
clear signature of protonconductivity with an activation
energy of about 1.0 eV. The QENS experiment revealed afast
dynamical process below 500 °C that was not observed by
EIS. The activation energyof the fast proton diffusion is
0.09 eV in the temperature range from 150 °C to 500 °C.},
