Beschreibung
Zusammenfassung:	An electrochemical cell, or stack thereof, wherein each cell of the stack comprises at least: a membrane electrode assembly (MEA), the MEA comprising at least: a cathode, an anode, and an anion exchange membrane therebetween, an inlet to the cathodic half-cell for the introduction of oxygen at a first pressure, and an outlet from the anodic half-cell for the transfer of oxygen at a second pressure, and means to provide a required power to the cell. In one embodiment, the purification and compression of oxygen occurs by utilisation of the following reaction pathway: AEM Cathode O2+4e−+2H2O→4OH−; AEM Anode 4OH−→O2+4e−+2H2O.
