Determination of the electrical characteristics of a commercially available yttria-stabilized zirconia electrolyte used in high-temperature thermodynamic studies

Journal Article


Abstract


  • The successful application of solid electrolytes in electrochemical cells for high-temperature thermodynamic studies depends to a large extent on an accurate knowledge of the Pe value of the electrolyte (the oxygen partial pressure at which the ionic conductivity and n-type electronic conductivity of the electrolyte are equal). Consequently, the Pe value of an electrolyte must be determined prior to its use in electrochemical cells. This paper describes the application of a coulometric titration technique in the quantitative assessment of the Pe values of a commercially available yttria-stabilized zirconia electrolyte. The experimentally determined Pe values of the electrolyte are reported and compared with Pe values reported in the literature.
