Abstract
Abstract An electrolytic cell for direct electrolysis of sea water wherein the cathode plates are parallelly elongated upward and downward longer than the anode plates to prevent Mg(OH)2 from adhering to said cathode plates and further prevent impurities from depositing in the cell to increase the efficiency of the electrolysis. The cell includes a feed chamber below the electrolysis chamber, and an electrolyte takeoff-precipitate withdrawal chamber directly above the electrolysis chamber, with the outlet port from the electrolysis chamber coincident with the inlet port to the electrolyte takeoff-precipitate removal chamber.
