Abstract
Oxygen reduction and incorporation into solid electrolytes and the reverse reaction of oxygen evolution play a crucial role in Solid Oxide Fuel Cell (SOFC) applications. However a detailed understanding of the kinetics of the corresponding reactions, i.e. on reaction mechanisms, rate limiting steps, reaction paths, electrocatalytic role of materials, is still missing. These include a thorough characterization of the binding potentials experienced by protons in the lattice. We report results of Inelastic Neutron Scattering (INS) measurements of the vibrational state of the protons in Ni-YSZ highly porous composites (75% to 90%), a ceramic-metal material showing a high electrical conductivity and thermal stability, which is known to be most effectively used as anodes for solid oxide fuel cells. The results are compared with INS and Deep Inelastic Neutron Scattering (DINS) experiments on the proton binding states in bulk ice.
