Proton diffusion in zirconate perovskites investigated by QENS

Abstract: The growth in both global demand for energy and fossil-fuel related environmental issues drive research on alternative fuel sources. Solid oxide fuel cells, which can operate on a variety of hydrogenous fuels, have been proposed as a clean and economical solution for power generation. A performance bottleneck for many of these devices is the electrolyte; the thin membrane separating the electrodes, which allows ions to migrate while preventing electrons from doing so. We propose here a quasielastic neutron scattering (QENS) experiment to investigate the diffusion of hydrogen ions in a class of doped zirconium-based perovskite materials. By establishing the parameters governing diffusion in these and comparing the behaviour of materials with different dopants, we hope to gain valuable information for improving the performance of future electrolyte materials.
