摘要：

An impedancemetry method is employed to investigate a porous gold electrode in contact with a solid oxygen-conducting electrolyte on the basis of zirconium dioxide of the same cationic composition, whose samples differ in the oxygen content. Upon reaching a stationary state, the interphase oxygen exchange rate is independent of the previous treatment and oxygen stoichiometry of the sample. The results are linked to the existence on the electrolyte surface of a layer whose structure differs from the bulk structure.
