用“三电极”法测量 Ｐｔ／ＺｒＯ２电极的过电位，利用反应级数分析和多步骤反应理论寻找电极的极化机制，发现Ｐｔ／ＺｒＯ２电极在４００～６００℃温度范围内的极化机制为自由电子由电极材料铂向ＺｒＯ２表层的传输过慢．
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℃.
