Electrochemical Investigation of Oxygen, Metal/ZrO_2 Interface

Li Qiu

Abstract

A-C Impedance spectroscopy and steady-state D-C polarization have been investigated tocompare oxygen diffusion on Pt, An, Ag, Ag-Pd four pasted electrodes and electrochemical reactionrate from 200℃ to 600℃. Electrode interface impedance has been calculated in the temperaturerange of 350-600℃. Experiments confirm the relationship of the exchange current density Io asa function of oxygen partial pressure P
