| 摘 要： | 利用对称电池Ｍ，ＭｘＯｙ│ＺｒＯ２（ＭｇＯ）│Ｍ，ＭｘＯｙ在高温下对固态参比电极的极化特征进行了研究。实验研究表明，在本实验的条件下，极化电流与超电势之间为线性关系。Ｍｏ／ＭｏＯ２参比电极的交换电析的交流密度远大于Ｃｒ／Ｃｒ２Ｏ３、Ｎｉ／Ｎｉ／ＮｉＯ、Ｃｏ／ＣｏＯ参比电极的交换电流密度。电极交换电流密度随参比电极中金属含量的啬及温度的升高而增大。根据实验测试得到了电极反应的活化能。

| Abstract: | A kind of symmetrical electrochemical cell of the type M, MxOy |ZrO2(MgO)| M, MxOy was used to study the polarization characteristic of solid state reference electrodes at high temperature.Experimental results show that the variation of overpotential with polarization current is linear.The exchange current desitics for the Mo/MoO2, Cr/Cr2O3, Ni/Ni/O and Co/CoO electrodes, in the order named, are decrcasing. The exchange current densities of all kinds of electrodes are also increasing with the increase of metal ratio in reference electrodes and temperature. The activation energy of the electrode reactions was calculated. |
