Abstract
Measurements of steady-state potentials of various electrodes made of oxide compositions are performed in cells containing electrolyte ZrO2 + 10 mol % Y2O3 at a temperature of 773 K in nonequilibrium gas mixtures N2 + O2 + 20 vol % CO2 + CO, with variable CO (0.1–5 vol %) and O2 (0.5–10 vol %) contents. After adding CO into a gas phase, potentials of all electrodes shift, to one degree or another. The shift is substantially affected by the O2 content. The electrochemical systems under study are of some interest for analyzing partial pressures of CO in gas mixtures. The discovered effect must be taken into account when employing such electrodes for the determination of partial concentrations of other components of a gas mixture, for example, oxygen.
