An electrochemical process for extracting oxygen from an oxygen-containing gas which uses an electrochemical cell having two zones separated by a multi-component membrane made from intimate, gas-impervious, multi-phase mixture of an electronically conductive phase and an oxygen ion-conducting phase.

An electrochemical process for extracting oxygen from an oxygen-containing gas which uses an electrochemical cell having two zones separated by a multi-component membrane made from intimate, gas-impervious, multi-phase mixture of an electronically conductive phase and an oxygen ion-conducting phase. In one zone a gas containing oxygen is passed in contact with the membrane. In the other zone a gas capable of reacting with oxygen is passed in contact with the membrane.
