METHOD FOR OPERATING DIFFERENTIAL PRESSURE WATER ELECTROLYSIS APPARATUS

摘要

A method for operating a differential pressure water electrolysis apparatus includes calculating in advance values of an electric current required for an electrolysis of water in response to pressures of a cathode-side electrolysis chamber, detecting a pressure of the cathode-side electrolysis chamber when the electrolysis of water is not carried out, determining whether or not the electrolysis of water is to be started, and starting the electrolysis of water with an electric current having a value equal to or higher than a value which is calculated in advance in the calculating of the values of the electric current and which corresponds to a detected pressure of the cathode-side electrolysis chamber when it is determined that the electrolysis of water is to be started.
