    摘要: A process and apparatus is provided for separating oxygen from a mixture of gases such as air. The apparatus includes an electrochemical cell that includes a cathode, an anode and an electrolyte. Oxygen in the air is reduced to the superoxide ion (O.sub.2.sup.-) at the cathode; the superoxide ion is transported across the cell through the electrolyte; and the superoxide ion is then reoxidized to oxygen at the anode and collected.
