The invention relates to apparatuses for the electrolytic production of hydrogen, which can be used as auxiliary or alternative fuel for internal combustion engines of automotive transport. The invention can also be used in chemical and petrochemical industries.The compact electrolyzer for the production of hydrogen includes a body (1) with a central flow-type cathode compartment of volume-porous foam material with a chemical-catalytic nickel-rhenium coating with low hydrogen release superpotential and flat perforated anodes (3) of a material with high oxygen release superpotential; two electrolyte outlet pipes (10), communicating with the lower ends with a feed capacity (7). The upper part of the body is made in the form of a domed cap (11), connected to a semiring chamber (12) with a hydrogen withdrawal pipe (13), communicating with a horizontally placed channel (14) with a shutter (15) for separation and withdrawal of oxygen, made of diamagnetic material, at the same time outside the channel (14) from the end of the semiring chamber are placed permanent magnets (16), and the middle part of the channel is covered with a two-section resistance winding with heat-insulating coating (17) forming two arms of an unbalanced bridge, connected to resistors, an automatic potentiometer (18) with scale of the percentage content of oxygen and a power supply (19). The electrolyzer is equipped with a metering device (6), a feeder (4) with a level gauge (5), as well as a recirculating pump (8), connected to the feed capacity (7) and the cathode compartment.
