Abstract: An electrolyzer for obtaining chemical products, comprising a cell having its inner surface made from a dielectric material, and filled with a circulating electrolyte; the cell accommodates current leads which are nonsoluble, the space between the current leads and the walls of the cell being filled with pieces of a conducting material, said pieces serving as a bulk electrode, and as these pieces react with the electrolyte, a coat of film is formed thereon, which promotes the bipolar action of said pieces when the current leads are energized; in addition, the cell is provided with a means for discharging slime and the products of electrolysis.
