Electrochemical apparatus and method

摘要

An electrochemical apparatus comprises an electrically conductive diamond electrode 2 configured to have a surface 4 which is disposed in contact with a solution 6 in use and a surface 8 which does not contact the solution in use; electrical contacts 10 configured to apply a voltage to the electrically conductive diamond electrode to perform an electrochemical process on the solution; and a heater 12 configured to apply pulsed heating to the surface 8 which does not contact the solution whereby the surface which is disposed in contact with the solution is heated via thermal conduction through the diamond electrode from the surface which does not contact the solution. The heater 12 may be a laser or electrical resistance heater in contact with the surface not contacting the solution.
