An electrolytic device and to a method for operating an electrolysis of water with at least one electrolysis cell, the electrolysis cell having an anode compartment having an anode and a cathode compartment having a cathode. The anode compartment is separated from the cathode compartment by a proton exchange membrane. The anode compartment is suitable for holding water and oxidising the water on the anode to form a first product including oxygen and the cathode compartment is suitable for holding water and reducing the water on the cathode to a second product including hydrogen. Furthermore, the electrolysis device includes a first gas precipitation device for precipitation of oxygen, the first gas precipitation device for carrying out a natural water circulation being arranged above the electrolysis cell.

Electrolysis unit and electrolyser

Various embodiments include a coil device for a power converter, the device comprising: a cooling plate; and a plurality N&#x2265;3 of coil windings. The cooling plate is thermally coupled to at least one end face of one of the plurality of coil windings. The coil windings are spatially offset from one another by an angle of 2&#x3c0;/N. The cooling plate defines a cooling channel extending at least partially around each of the plurality of coil windings.

Coil device

An electrolysis unit and to a method for electrochemically decomposing water into hydrogen and oxygen. The electrolysis unit has at least two electrolysis modules. The electrolysis unit also has exactly one first gas separation device for a first product gas including oxygen and exactly one second gas separation device for a second product gas including hydrogen. The first gas separation device is connected to the at least two electrolysis modules by respective first lines. The second gas separation device is connected to the at least two electrolysis modules by respective second lines. The at least two first lines have the same first length. The at least two second lines likewise have the same second length.
