Abstract
The invention relates to an electrolysis arrangement for the electrochemical production of hydrogen and oxygen from an alkaline electrolyte having anode and cathode separators for the separation of oxygen and hydrogen from the electrolyte, and an anode and cathode pipe system to circulate electrolyte between anode and cathode sections of an electrolysis stack of the electrolysis arrangement. Control valves and interconnections are configured so that dependent on an electrolyte flow rate passing first, second and third control valve, oxygen and hydrogen depleted electrolyte withdrawn from the separators can be supplied unmixed, partly mixed or fully mixed to the anode and cathode sections of the electrolysis stack to control hydrogen to oxygen and oxygen to hydrogen crossover in the electrolysis arrangement.
