Abstract

There is disclosed a method of operating an electrochemical cell for use in the electrolysis of water to produce ozone, the cell comprising a first electrode and a second electrode separated by a Cation Exchange Membrane, wherein the first and second electrodes each has an active surface formed from electrically conductive diamond, in a first mode of operation the electrochemical cell having a flow of electrical current in a first polarity, whereby the first electrode functions as an anode and the second electrode is a cathode; the method comprising providing the electrochemical cell in the first mode of operation with a supply of current to the electrodes in the first polarity to produce ozone at the first electrode for a first period of time; and providing the electrochemical cell in a second mode of operation with a supply of current to the electrodes in a second polarity, opposite to the first polarity, for a second period of time. An electrochemical cell for use in the aforementioned method is also disclosed.
