Zusammenfassung:	The invention relates to a process for controlling an electrolyzer. Determination of four different electrolyte flow rates at certain positions in the electrolyzer makes it possible to determine a compensation flow rate which establishes a fluidic connection between the anode side and the cathode side of the electrolyzer. The compensation system makes it possible to achieve at least partial concentration compensation between the electrolyte concentration on the anode side and the electrolyte concentration on the cathode side. The compensation flow rate makes it possible to draw conclusions about the operating state of the electrolyzer. The compensation flow rate makes it possible to determine a permeation flow rate between the anode space and the cathode space of one or more electrolysis cells. The permeation flow rate is correlated with a predetermined differential pressure between the anode space and the cathode space which improves the efficiency of the electrolyzer.
