【摘要】 用“三电极法”测量了 ＺｒＯ２电池中Ａｇ和Ｐｔ电极的极化曲线，发现Ａｇ电极的极化倾向大于 Ｐｔ／电极。 采用电化学方式对上述电极进行活化处理，使电极的极化倾向大为降低，并将电极活化归结为ＺｒＯ２电解质表面的部分还原。更多还原

【Abstract】 The polarization curves of Ag and Pt electrodes in a ZrO2 cell were measured with "three electrodes method", and greater over-potential value of Ag electrode than Pt electrode was discovered. An electrochemical treatment was taken to activate the electrodes and the activation mechanism was proposed.更多还原
