Abstract: An electrolytic reaction system for generating gaseous hydrogen and oxygen includes a reaction chamber for accommodating an electrolyte as well as an electrode arrangement, which is formed of anodic and cathodic electrodes. Between lateral surfaces of electrodes arranged to be spaced apart from one another, at least one flow channel for the electrolyte is formed, which extends between a first axial end for admitting the electrolyte into the electrode arrangement and a second axial end for discharging the electrolyte out of the electrode arrangement. The at least one flow channel has at least one first flow cross-section and at least one second flow cross-section, wherein the second flow cross-section has a smaller size than the first flow channel, and the comparatively smaller second flow cross-section is formed in a partial section of the at least one flow channel closest to the second axial end of the electrode arrangement.
