CHECKING THE TIGHTNESS OF AT LEAST ONE MEMBRANE OF AN ELECTROLYZER

摘要

The invention relates to a method for checking the tightness of at least one membrane (7) of an electrolyzer (1) that has two electrolyzer volumes which are separated from each other by the at least one membrane (7) and is designed to produce two product gases (10, 30) from a liquid feedstock (50) using an electrolysis process; in said method, a mass flow of the liquid feedstock (50) between the two electrolyzer volumes is determined and is evaluated in order to check the tightness of the membrane.
