Electrolysis cell (10) comprises a DC voltage source (12) with positive and negative terminals (14, 16) to alternating electrodes (18) and (20) respectively. The source (12) produces a voltage that cycles between a minimum voltage Vmin and a maximum voltage Vmax where Vmin = 0 volts, and Vmax = Vmin + ?, where ? > 0 volts. Thus, the voltage provided by the DC source (12) is in the form of a periodic wave having a period T, and frequency f. As the voltage source (12) cycles its voltage from Vmin to Vmax, there is an intermediate peak VP1 between Vmin and Vmax. When the voltage reaches VP1, it decreases for a period of time TP1, before again ramping up to voltage Vmax. The voltage then decreases relatively rapidly to Vmin, completing one cycle of period T.
