摘要:

模拟海洋电极的使用环境,以电极的化学反应过程为基础,利用粉压成型工艺,制成φ10高度分别为5 mm、8 mm、11 mm的3组具有不同表面积的电极,并研究了电极表面积对其噪声及稳定性的影响。通过测试得出高度为5 mm的电极最不稳定,噪声最大;而高度为11 mm的电极稳定性最佳,且噪声最低。实验结果表明,增加电极的表面积,有利于提高电极的稳定性,并降低电极的噪声。

关键词: 电极, 电化学噪声, 电极面积

Abstract:

With the electrochemical reaction principle of the electrode as the theoretical basis,the application environment of marine electrode is simulated.Pairs of electrodes with different surface area are then made by powder pressure molding process.The heights of these electrodes were 5 mm,8 mm,11 mm,respectively,with the same diameter 10 mm.The influence of superficial area on electrical noise and stability of electrode is studied.The lowest electrical noise 0.961 nV/ Hz is obtained for the electrode with a height of 11 mm.The investigation shows that the increase of superficial area can improve the stability and reduce the electrical noise of electrode.

Key words: electrode;electrochemical noise;area of electrode
