Abstract:
A method for the electrolysis of water, in which water is decomposed electrolytically from an electrolysis medium and the electrolysis gases hydrogen and oxygen obtained are each separated from the liquid electrolysis medium in a gas separator, comprising the steps of:controlling a supply of water for balancing out the water consumption resulting from the electrolysis by determining during electrolysis an electrolysis medium volume from a total amount of electrolysis medium,measuring at least one physical quantity which is characteristic of the electrolysis, a variation in said physical quantity causing a change in the electrolysis medium volume in addition to and independent of the change in the electrolysis medium volume resulting from the water consumption,using a deviation of the measured quantity from a predetermined reference value to calculate an associated change in the electrolysis medium volume, andaccounting for said calculated change in the control of the water supply, wherein water is added as required.
