Hebb-Wagner polarization measurements were performed on yttria-stabilized zirconia in which, for the first time, an anodically blocked electrode was employed. The data for the hole conductivity determined by the method is in complete agreement with the results known so far from the literature. The effect of ion blocking is achieved by an extreme reduction of the oxygen exchange rate at the solid/gas interface after the yttria-stabilized zirconia surface had been exposed to In{sub 2}O{sub 3}. Owing to the particular properties of this electrode, impedance spectroscopy can even be employed, which has never been reported before for use in determining the hole activity of a solid electrolyte.
