Abstract
The present invention aims to provide an activated cathode enabling a long-time stable operation with hydrogen overvoltage maintained at a low value, keeping a high remaining rate of the catalyst element after a cease of operation for a short-circuiting and after an electrolysis operation at a high current density, restricting catalyst loss to a little, and having a strong resistance to contamination caused by electrolyte impurity elements.
