Cross-flow water electrolysis

The invention relates to methods for the alkaline electrolysis of water, in which an electrolyte is pumped in the circuit between an anode half cell and a cathode half cell, in order to thereby keep the electrolyte concentration constant throughout the electrolysis process. With this procedure, know...

Beschreibung
Zusammenfassung:	The invention relates to methods for the alkaline electrolysis of water, in which an electrolyte is pumped in the circuit between an anode half cell and a cathode half cell, in order to thereby keep the electrolyte concentration constant throughout the electrolysis process. With this procedure, known disadvantages from the prior art, such as the formation of a Donnan potential and the formation of flow currents, can be substantially eliminated and the energy yield and effectiveness of the method is thereby improved. The invention also relates to electrolysis devices with which said methods can be carried out.
