Abrégé

The invention relates to an electrolytic reaction system (1) for producing process gases in the form of gaseous hydrogen and oxygen, comprising at least three electrode assemblies (2), each of which comprise a plurality of hollow cylindrical electrodes that are arranged coaxially to one another and are positioned one inside the other. At least three electrode assemblies (2) are uniformly distributed about a common central vertical axis (4), and a hollow cylindrical container wall (5) for receiving an electrolyte is provided for each electrode assembly (2). A cover element (7) is supported on the upper end face (6) of each of the container walls (5), and the cover element (7) has through-openings (8) which run in the vertical direction and which are designed to discharge process gases produced within the container walls (5). A collecting hood (9) is provided on the cover element (7) in order to combine process gases exiting the individual through-openings (8). An electromagnetic coil (10) which is designed in the form of a ring and comprises a central air core (11) is received by the cover element (7) or is mounted on the cover element (7) and is aligned such that the central vertical axis (4) of the at least three electrode assemblies (2) passes through the central air core (11).

Abrégé

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.

Abrégé

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.
