In this paper, we provide a novel electrode switch (ES) method to improve the stability of the alkaline electrolyzer toward water splitting. The voltage of the alkaline electrolyzer consisting of commercial Ni mesh electrodes utilizing the ES mode exhibits extreme stability because highly active Ni oxide(hydroxide) with oxygen defects is formed during the hydrogen evolution reaction (HER) polarization process.
