Abstract

PURPOSE:To lower H2 overvoltage in a short time and carry out electrolysis under a low voltage, by stopping electrolysis appropriately, maintaining the cathode potential at a specified value on the basis of the saturated calomel electrode for a specified time, and then carrying out electrolysis again, when the titled electrolysis is carried out in an electrolytic cell with cation exchange membrane.
