Electrochemical oxygen concentrator

The present invention pertains to an electrochemical oxygen concentrator for separating oxygen from a gas mixture containing oxygen. An electrochemical cell for separating oxygen from the ambient air can be manufactured in a simple manner and inexpensively and both the electrodes and the electrolyte can be manufactured as thin layers. The electrochemical cell has a metallic housing plate (), a gas-permeable carrier plate () located on the housing plate (), a system of layers on the carrier plate (), including a first electrode (), an electrolyte () and a second electrode () exposed to the ambient air, wherein the oxygen generated is drawn off via a discharge opening at the housing plate ().
