Abstract

For operation, PEMFCs require among other things a compressor for the cathode air, and a system for removing the water which is generated on the cathode side as a result of the electrochemical reaction. According to an embodiment of the present invention the removal of water is supported in that the fuel cell is made to rotate by way of an electric motor so that the water contained in the cathodes of the fuel cell can be extracted by centrifugal force. To this effect the air channels on the cathode side are arranged so as to extend radially or in a spiral shape from the inside towards the outside. In this way the efficiency of the fuel cell can be significantly improved.
