Abstract: A device for producing hydrogen in an electric field includes a shaft rotationally coupled via bearings to a vacuum protection housing, which encloses a disc like structure fastened to the shaft that supplies a split medium provided through inlet channels situated at one longitudinal end of the shaft to split cells arranged at a periphery of the disc like structure. Each split cell includes first and second electrodes. To the vacuum protection housing are fastened diffusor-spirals where a produced gas and a material residue from the split cells are provided through a plurality of nozzles, each of which is arranged inside one of the diffusor-spirals with minimal clearance between an outer wall of the nozzle and an inner wall of the associated diffusor-spiral. A rotation of the disk like structure is supported by a gas pressure generated by the produced gas emitted from the nozzles.
