The purpose of this chapter is to describe methods for determining the oxygen stoichiometry (bulk and surface oxygen activities) and transport properties in non-stoichiometric oxides using solid electrolyte cells. These oxides are generally referred to as “mixed ionic-electronic conductors” (MIEC). It is customary to consider that in a MIEC, the ionic or electronic transport number is higher than 0.01 and that the total electrical conductivity is sufficiently high, i.e., higher than 10-5 S.cm-1. Emphasis will be given on sources of error.< Réduire
