Abstract
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 ().
