REGENERATION OF AN ELECTRODE IN AN ELECTROLYSER

A method of regenerating the electrodes of an electrolyser with the electrodes in-situ within the electrolyser is disclosed. The method comprises providing at the electrodes in-situ in the electrolyser a salt solution and reacting the salt solution with the electrodes to cause regeneration of the electrodes. Also, a system for regenerating the electrodes comprising an electrolyser system and a storage container containing a salt capable of causing regeneration of the material of the electrodes when mixed with water to form a treatment salt solution. A controller for controlling the regeneration of the electrode in dependence on the availability of a suitable period of time and a sufficient power supply is also disclosed.
