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.

Abstract: Flow type electrochemical cells are disclosed. The electrochemical cell has an anode half-cell, a cathode half-cell, and permeable separating layer. The half-cells are bounded by side elements. Respective porous electrodes are housed in the half-cells. The permeable separating layer is disposed between the anode half-cell and the cathode half-cell. An electrolyte region connected to an electrolyte feed and an electrolyte outflow region connected to an electrolyte drain are further provided. An electrolyte inflow region and an electrolyte outflow region are disposed on opposite sides of the porous electrodes such that inflowing electrolyte flows through the porous electrode perpendicularly to the permeable separating layer.
