Abstract
A method for brine electrolysis using a gas electrode and an electrolytic cell therefor, in which gas electrode 31 permeable to gas and liquid is arranged in cathode chamber 24 in contact with ion-exchange membrane 22. Sodium hydroxide produced on electrode substance 30 of gas electrode 31 easily penetrates the gas electrode and is recovered from the cathode chamber. No sodium hydroxide is produced within the ion-exchange membrane so that penetration of sodium hydroxide into the anode chamber is thereby prevented.
