摘要
用“三电极法”测量Pt/ZrO2 电极系统的过电位。用数学模拟分析从中分离出电化学过电位。发现该电极系统在 4 0 0～ 60 0℃温度范围内极化的原因是电子在Pt与ZrO2 表层之间的输运不够快。提出了一种活化电极工艺。
The over-potential of Pt/ZrO 2 electrode was measured with ‘three electrode’methode,and the electochemical over-potential was separated with mathematical method.The reason of Pt/ZrO 2 electrode polarization could be deduced to slow transportation of electrons between electrode material and ZrO 2 surface layer.A process was proposed to activate the electrode.
