  • Water management and cooling during electrolysis
    Patent number: 8647494
    Abstract: A method of electrolysing water, using a water electrolyser having cathode and anode compartments respectively on either side of a hydrophilic polymer cation-exchange membrane, the method comprising: (i) adding water to the anode compartment only, such that the cathode compartment is predominantly free of water in liquid form; (ii) electrolysing the water to form hydrogen gas in the cathode compartment and oxygen gas in the anode compartment; and (iii) re-circulating the hydrogen gas through the cathode compartment.
