In an electrolytic cell, e.g. a cell for electrolysing alkali metal chloride solutions using one or more graphite anodes and a mercury cathode, the optimum electrode gap with regard to cell voltage is obtained by applying a constant voltage between the electrodes and advancing the anode towards the cathode until the increase in current intensity ceases to be a straight-line function of the amount by which the electrode gap is reduced and rises sharply. This occurs before short circuiting. The anode may be withdrawn subsequently by a specific distance empirically determined so as to obtain the optimum electrode gap with regard to the faradic output of the cell. The anode may be advanced by an apparatus as claimed in Specification 851,415. |
