Abstract (en)

[origin: WO0030187A2] An electrolytic cell (1) and method for decreasing the power consumption of an electrolytic cell (1) having a fixed designed current capacity in one aspect comprises refitting an electrolytic cell (1) with additional cathodes and anodes to lower the overall current density of the cell. In order to accommodate the additional anodes, the cathode-to-cathode spacing (CS) can be reduced and the cathodes can also be reconfigured to provide a narrower cathode tube structure (11). This can be accomplished by decreasing the spacing between opposed cathode plates (12). This modification permits operation of the cell (1) at the original designed current capacity at a significantly reduced power consumption. New cell manufacture is also contemplated.
