Abstract

See full text

An electrolysis apparatus comprising: an electrolytic cell in which a sulfuric acid solution is fed and discharged; a conductive anode and cathode electrode of diamond composition; a feeding unit for feeding the sulfuric acid solution to the electrolytic cell; a power supply unit for applying a voltage between the anode and cathode electrodes; and a power control unit for controlling the power supply unit such that a forward voltage is applied between the anode and cathode during normal electrolysis with the polarity applied between the anode and cathode inverted under predetermined conditions during intervals between normal operation to dissolve precipitates of sulfur generated in the electrolytic cell for stabilizing the electrolysis operation.
