Abstract (en)
[origin: EP1283281A2] An electrolysis cell (1) has anode chamber(s) (3) having anode (4), and cathode chamber(s) (2) having oxygen-consuming cathode (5) and a pressure of 1.05 bar or more, and cation exchange membrane (6) for separating the chambers. An aqueous solution of hydrogen chloride is passed into the anode chamber(s), and oxygen-containing gas is passed into the cathode chamber(s), to electrochemically prepare chlorine.
