MULTIELEMENT MATRIX FILTER-PRESS WATER ELECTROLYSIS UNIT Russian patent published in 2013 - IPC C25B1/08 C25B1/02 

FIELD: metallurgy.

SUBSTANCE: invention refers to a multielement matrix filter-press water electrolysis unit consisting of electrolysis cells containing porous cathode, anode and electrolyte-containing matrix, as well as wetting elements containing an electrolyte cavity and a porous membrane permeable for water vapours and non-permeable for liquid, with water supply to cathodes in the form of water vapour mixed with hydrogen; besides, wetting elements and electrolysis cells are spatially separated from each other and insulated as to metal and electrolyte and combined into two separate sections, in which vapour-hydrogen mixture circulates via a common closed circuit, thus maintaining the same temperature in sections; with that, in the wetting element liquid electrolyte is separated from gas of vapour-hydrogen mixture with a hydrophilic membrane with gas shutoff properties, and gas pressure is higher than electrolyte pressure.

EFFECT: reliable and high-efficient operation during a long period of time.
