Zusammenfassung:	A method of protecting a nonoperational CO2 electrolysis stack from corrosion, includes: at least partly emptying an electrolyte from parts of a first electrolysis cell and/or of a first feed and/or of a first drain and/or of an overall feed which is connected to the first feed and the second feed and is designed to provide an inlet for the first feed and the second feed and/or of an overall drain which is connected to the first drain and the second drain and is designed to provide an outlet for the first drain and the second drain. The electrolyte which is removed by the at least partial emptying is exchanged for an inert gas or a mixture including an inert gas and liquid droplets present therein, wherein the inert gas is CO2.
