Abstract: An electrolytic cell having an anode compartment and a cathode compartment separated by a porous diaphragm. The cell has inlet and outlet pipes for electrolyte. A valve controls the supply of electrolyte. A gas outlet-pipe is connected to the anode compartment or to the cathode compartment. A valve is disposed in the gas outlet-pipe and is variable as to its opening. A vessel in the cell has an upper part thereof in communication with the gas outlet-pipe upstream of the valve and a lower part of the vessel is in communication with the compartment to which the gas outlet-pipe is connected. A float in the vessel is operatively connected with the valve in the gas outlet-pipe and progressively closes as it rises and opens the valve as it moves downwardly in response to electrolytic height variations. The valve is in an intermediate, partially closed position during normal operation of the cell during which the cell is partially filled with electrolyte.

Abstract: A diaphragm cell for use in the electrolysis of an aqueous solution of alkali metal chloride. The cell is provided with a chamber divided by a diaphragm into an anode compartment having at least one anode therein and a cathode compartment having at least one cathode therein. The cathode has a catalytic surface different from the active surface of the anode. The cathode surface is made of a material which catalyses the decomposition of hypochlorite ions.
