A device (20) for extracting oxygen from water (16) has a proton exchange membrane (4) and surface electrodes (2, 6) arranged on both sides of the proton exchange membrane (4) for forming an anode on the one hand and a cathode on the other, whereby on the An anode side (22) is a water space (24) for the water (16) is provided, which has an outlet for the oxygen obtained, and wherein the cathode side (23) is accessible to ambient oxygen (18). The proton exchange membrane (4) is arranged in the form of a cylinder jacket section around the water space (24), and the water space (24) is sealed on its sides not covered by the proton exchange membrane (4) except for line connections (10, 27). |
