AIR-COOLED PROTON-EXCHANGE MEMBRANE FUEL CELL CAPABLE OF WORKING WITH COMPRESSED GASES, AND FUEL CELLS STACK

The present disclosure relates to fuel cells, in particular to high-temperature air-cooled fuel cells. A fuel cell 1 comprises a bipolar plate 2 and a membrane-electrode assembly 3. The bipolar plate 2 comprises an anode plate 5, a cathode plate 6 and a layer 7 of air cooling channels between the anode plate 5 and the cathode plate 6. Channels for an oxygen-containing gas are made in the cathode plate 6. Channels 10 for hydrogen are made in the anode plate 5, which are covered by the membrane-electrode assembly 3 contacting the anode plate 5. A fuel cell stack comprises at least two fuel cells, wherein the membrane-electrode assembly of one fuel cell contacts the anode plate of said one fuel cell, thus covering the channels for hydrogen, and contacts the cathode plate of said another fuel cell, which adjoins said one fuel cell, thus covering the channels for an oxygen-containing gas. The technical effect consists in reducing weight-dimension characteristics of the fuel cell and the fuel cell stack, while simultaneously reducing power consumption required for cooling, and increasing specific capacity per unit weight and power efficiency.
