Method for operating an electrolysis plant, and electrolysis plant

Abstract

The invention relates to a method for operating an electrolysis plant which has an electrolyzer for generating hydrogen and oxygen as product gases, wherein water is fed as educt water to the electrolyzer and split into hydrogen and oxygen at an ion-exchange membrane. Prior to splitting, the educt water is brought into a thermodynamic state close to the boiling point of the water in terms of the pressure and temperature and is fed in this state to the membrane. Educt water is brought to a boil at the membrane and converted into the gas phase, wherein the water in the gas phase is split at the membrane. There is also described an electrolysis plant having an electrolyzer for generating hydrogen and oxygen as product gases.
