Abstract (en)
[origin: WO2022128855A1] The invention relates to a method for electrolysis, wherein H2O is brought into contact with an anode (2) and a catholyte is brought into contact with a cathode (3), wherein the catholyte contains an additive, wherein an electrical voltage is applied between the anode (2) and the cathode (3) such that oxygen is formed on the anode (2) and the additive is reduced on the cathode (3), and wherein protons and the reduced additive are brought into contact with a catalyst (4) such that the reduced additive is oxidised and hydrogen is formed from the protons. The additive means that the electrolysis can be carried out under low pressure and hydrogen can still be obtained at high pressure. This simplifies the design of the electrolysis cell and prevents efficiency-reducing gas cross-permeation.
