A method for operating an electrolysis device () for producing hydrogen uses a water circuit. Water from a polymer electrolyte membrane (PEM) electrolyzer () is cooled in a cooling device () and subsequently led to an ion exchanger () for processing the water. The water, after the processing in the ion exchanger (), is fed to the PEM electrolyzer (). Heat is removed from the water before feeding the water to the cooling device (). A part of this removed heat is fed again to the water after the processing in the ion exchanger () and before entry into the PEM electrolyzer ().

Electrolysis device and method for operating an electrolysis device

A method is provided for running up/starting up an electrolysis device (), which device includes a reactor container () which is arranged downstream of an electrolyzer () and in which oxygen reacts with hydrogen into water, in order to reduce an oxygen share in a hydrogen gas flow coming from the electrolyzer (). The electrolysis device () is operated with a predefined operating pressure. Upon running up/starting up the electrolyzer (), the hydrogen gas flow coming from the electrolyzer () is led past the reactor container () via a bypass conduit ().
