Abstract: The invention pertains to an electrolyser for producing hydrogen (H2) and oxygen (O2) as product gases. It includes an electrolysis module and a gas separator for phase separation of the product gas from water. The electrolysis module is connected to the gas separator via a product flow line, and a return line with a circulation pump connects the gas separator back to the electrolysis module for separated water. A bypass line with a valve allows water to be supplied from the gas separator to the electrolysis module during standstill. The invention also covers a method for operating the electrolyser, where in standstill mode, the electrolysis current is stopped, and a safety deactivation is initiated. Water is automatically driven into the electrolysis module due to a hydrostatic differential pressure (?p) from a predefined height difference (?h), flooding the electrolysis module.

Abstract: Disclosed is a method for operating an electrolysis plant for producing hydrogen and oxygen as product gases, wherein the oxygen product gas, which additionally contains hydrogen as a foreign gas, is fed from an electrolyser to a downstream gas separator, wherein when a predefined limit value for the hydrogen concentration in the oxygen product gas is exceeded, an inert gas (L) is fed to the gas separator such that the hydrogen concentration in the oxygen product gas is lowered. The invention further relates to a corresponding electrolysis plant.

Abstract: The invention relates to an electrolysis system having a plurality of electrolytic cells for water electrolysis. An anode-side water circuit leads from an anode-side outlet, via an oxygen separator, a main pump and a cooling device, to an anode-side inlet of an anode chamber. A cathode-side water circuit leads, similarly, from a cathode-side outlet, via an oxygen separator, a main pump and a cooling device, to a cathode-side inlet of a cathode chamber. Cleaning of the water during non-operation of the electrolysis system is achieved by adding an anode-side partial-flow branch, which leads from a branch-off point, via an auxiliary ion exchanger, to a collection point in the anode-side water circuit.
