A circuit arrangement for increasing the life of electrochemical electrodes comprises a source of DC (1), a switching device (2), three electrodes (3, 4, 5) of which one is always a cathode (3) and another is always an anode (5) while the potential of the third (4) is controlledly varied by control unit (6) so that it functions alternatively as a cathode and as an anode. <IMAGE> |
