Abstract
The invention relates to a portable electrochemical oxygen generator, comprising: a proton-conducting polymer electrolyte membrane (PEM) (1); a water-filled, porous anode (2), with an anode chamber (6); a porous air cathode (3), with a cathode chamber (5), whereby the PEM, anode and cathode form a PEM-cell; a direct current source (4); a cathode gas condensate separator (7), connected to the anode chamber by means of a condensate line and a pump (8), to form a water-cooling circuit; a reservoir with reducing valve (9) for the oxygen generated and a controller/regulator unit (11), for the control/regulation of the oxygen generation, the air feed and the temperature of the PEM-cell.
