Abstract
Electrochemical impedance spectroscopy (EIS) was applied to study the effect of heat treatment conditions (temperature and time of heating) on electrical properties of electrochemical gas sensors. The use of EIS method allowed observing the effect of undesirable chemical reaction in electrochemical cells (sensors) by the detection of change of electrical properties at the very early stage of such reaction. Addition of barium carbonate to lithium carbonate resulted in long-term stabilization of electrical properties of the system carbonate phase solid electrolyte. It was found that impedance spectra of the cell: carbonate vertical bar Au vertical bar YSZ vertical bar Pt with inner An electrode provided the most useful information about reactivity progress between both phases.
