Pulsed electrolysis with reference to the open circuit voltage

摘要

The energy consumption in electrolysis processes is to be reduced. Proposed for this purpose is an electrolysis process in which a pulsed voltage is applied between an anode and a cathode, and the currently applicable OCP (open circuit potential or open circuit voltage) that the cathode has in a deenergized state with respect to a reference system is repeatedly measured or an OCP profile is prescribed. Closed-loop control of the pulsed voltage or of the pulsed current between the anode and the cathode is performed in such a way that a working potential of the cathode in the energized state with respect to the reference system has a prescribed profile (PF) in relation to the respectively current OCP or the prescribed OCP profile. The prescribed profile (PF) has at least one portion (t
