Abstract:
An electrochemical process for extracting oxygen from an oxygen-containing gas which comprises(A) providing an electrochemical cell comprising first and second zones separated by a solid multi-component membrane comprising an intimate, gas-impervious, multi-phase mixture of an electronically conductive phase and an oxygen ion-conductive phase,(B) passing a gas containing N.sub.2 O, NO, NO.sub.2, SO.sub.2, or SO.sub.3, or a mixture thereof in contact with the membrane in the first zone, and(C) passing a gas capable of reacting with oxygen in contact with the membrane in the second zone.
