A differential gas pressure control device for an electrolytic cell (1) which comprises an anode compartment (2) in which in operation a gas is generated, a cathode compartment (4) in which in operation a gas is generated, a pipe (11) leading from the anode compartment(s) (2) of the cell (1) through which in operation anode gas passes, and a pipe (17) leading from the cathode compartment(s) (4) of the cell through which in operation cathode gas passes, in which the control device comprises a moveable flow controller positioned so as to control the flow of anode gas in the pipe (11) and a moveable flow controller positioned so as to control the flow of cathode gas in the pipe (17), in which the flow controllers are operatively connected, and in which in operation the anode and cathode gases independently act upon the flow controllers which control the flow of cathode gas and of anode gas respectively. |
