Patent ID: 11346012

Abstract:
An electrochemical cell for treating a fluid, the electrochemical cell comprising: at least two opposing electrodes defining a flow path for the fluid between the electrodes, where at least one of the electrodes is formed of electrically conductive diamond material; drive circuitry configured to apply a potential across the electrodes such that a current flows between the electrodes when the fluid is flowed through the flow path between the electrodes; and a housing in which the electrodes are disposed, the housing comprising pressure seals configured to containing the fluid within the fluid path and a support structure for supporting the electrodes, wherein the support structure and the pressure seals are configured such that the electrochemical cell has an operating pressure in a range 2 to 10 bar within which the electrodes are supported without fracturing and within which the fluid is contained within the flow path, wherein the electrodes are spaced apart by a distance in a range 0.5 mm to 4 mm, and wherein the drive circuitry is configured to apply a potential across the electrodes giving a current density ≥15,000 Amp/m2 over an electrode area of at least 20 cm2 for an operating voltage of no more than 20 V.
