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.

Abstract

The invention relates to an electrolytic reaction system (1) for producing gaseous hydrogen and oxygen, comprising a reaction chamber (2, 69) for accommodating an electrolyte and an electrode arrangement (3) which is composed of a plurality of anodic and cathodic electrodes (5, 6). At least one flow channel (71) for the electrolyte is formed between jacket surfaces of electrodes which are spaced apart from each other, said flow channel extending between a first axial end for the entry of the electrolyte into the electrode arrangement (3) and a second axial end for the exit of the electrolyte from the electrode arrangement (3). The at least one flow channel (71) has at least one first flow cross-section and at least one second flow cross-section, the second flow cross-section being smaller than the first flow cross-section and the comparatively smaller second flow cross-section is formed in a partial section of the at least one flow channel (71), which is closest to the second axial end of the electrode arrangement. An improved, in particular a more efficient electrolytic reaction system (1) is thereby achieved.
