Abstract (en)
[origin: WO2021228412A1] The method for operating a water electrolysis device for generating hydrogen and oxygen from water has a PEM electrolyser (1), to which water is supplied for generating the hydrogen and the oxygen together with water for cooling. The cooling water is conducted in the circuit and treated by means of an ion exchange unit (17). Only part of the water conducted in the circuit is supplied to the ion exchange unit (17) and another part is supplied to the PEM electrolyser (1) via a bypass (13), circumventing the ion exchange unit (17).
