Abstract

The chemical stabilities of electrode-electrolyte interfaces have been investigated for the following two cases: (1) interaction between yttria-stabilized zirconia electrolyte and platinum electrode is selected as an example to confirm the validity of the present approach; (2) interaction between β″-alumina electrolyte-molybdenum electrode in AMTEC (alkali metal thermoelectric convertor): the chemical potential diagrams for the NaAlMoO system have been constructed to examine the transfer of sodium in the electrolyte-electrode interface vicinity as functions of partial pressure of oxygen and sodium.
