Abstract: The polarization curves of Pt/ZrO2 electrode were measured with three electrode method . The multi-step reaction theory and reaction class analysis were applied in analyzing the electrode reaction mechanism, and it was found that the slow electron transportation between Pt and ZrO2 became the rate determining step under the temperature between 400℃ and 600℃.

Key words: Pt, ZrO2, electrode, oxygen sensor
