Abstract

What is proposed is an apparatus for conducting an electrolysis with an oxygen depolarized cathode, comprising: (a) an electrolyzer 1 which (b) is connected on the reactant side via an inlet control valve 2 to an oxygen source 3, and (c) on the product side has at least one off gas line 4, (d) which has at least one pressure regulator (PT) 5, at least one gas analyzer (QI) 6, at least one flow regulator (FT) 7 and at least one outlet control valve 8, wherein (e) the pressure regulator 5 controls the inlet control valve 2, (f) the gas analyzer 6 controls the flow regulator 7 or the outlet control valve 8 and/or (g) the flow regulator 7 controls the outlet control valve 8.
