Abstract

An electrolysis unit and to a method for electrochemically decomposing water into hydrogen and oxygen. The electrolysis unit has at least two electrolysis modules. The electrolysis unit also has exactly one first gas separation device for a first product gas including oxygen and exactly one second gas separation device for a second product gas including hydrogen. The first gas separation device is connected to the at least two electrolysis modules by respective first lines. The second gas separation device is connected to the at least two electrolysis modules by respective second lines. The at least two first lines have the same first length. The at least two second lines likewise have the same second length.
