  • AIR-BREATHING FUEL CELL AND CELL STACK FOR THE OXIDATION OF IONS USING OXYGEN
    Publication number: 20140377681
    Abstract: The invention describes an air-breathing fuel cell for the oxidation of ions with air or oxygen, having an anode half cell and a cathode half cell. A first ion-conducting membrane and a second ion-conducting membrane is introduced between the half cells, and the second ion-conducting membrane is coated at least in regions on the side orientated towards the cathode half cell with a catalyst for the reduction of oxygen. According to the invention, the air-breathing fuel cell is characterised in that an oxidation zone for the oxidation of ions with negative standard electrode potential is provided between the ion-conducting membranes.
