Electrode and electrochemical cell comprising the same

摘要

An electrode assembly for use in an electrochemical cell for the production of ozone from water is provided, the electrode assembly 2 comprising an electrode body 4, 6 formed from a polycrystalline diamond, the electrode body comprising first and second opposing contact surfaces, the first contact surface for contacting a semi­permeable membrane 8; wherein the electrode assembly further comprises a first layer comprising an electrically conductive material 10a, 12a, the first layer extending across at least a portion of the second contact surface of the electrode body 4a, 6a. Preferably there is also a second layer of electrically conductive material 10b, 12b applied over the first layer. An electrochemical cell comprising the electrode assembly and its use in the production of ozone by the electrolysis of water is also provided.
