  • Direct oxidation fuel cell and method for operation thereof
    Patent number: 7927753
    Abstract: The invention relates to a method for operating a direct oxidation fuel cell in which at least one fluid fuel is transported from a fuel reservoir via a fluid distribution structure to a membrane electrode assembly, the transport of the fuel being effected passively, i.e. without convection. Furthermore, the invention relates to a corresponding direct oxidation fuel cell.

  • Device with a channel conducting a flowable medium and a method for removing inclusions
    Patent number: 7887621
    Abstract: The invention relates to a device which comprises a channel (1) carrying a flowable medium. The due operation and/or maintenance of the device is associated with the formation of inclusions (3) inside the channel (1) of a fluid or gas distinct from the aforementioned medium. The channel (1) is configured in such a manner that the inclusions are moved towards a channel exit (4) by capillary forces. The invention also relates to a method for removing inclusions (3) from corresponding devices.

  • FUEL CELL AND METHOD FOR PRODUCTION THEREOF
    Publication number: 20100221636
    Abstract: The invention relates to a fuel cell which has a membrane-electrode unit comprising an ion-conducting membrane with catalyst layers which are disposed on oppositely situated surfaces of the membrane and serve as anode and cathode, and also possibly an anode-side and/or a cathode-side gas diffusion layer, the membrane-electrode unit having adjacent regions with different diffusion transport for educts and/or products. The invention likewise relates to a method for the production of fuel cells of this type.

  • DIRECT OXIDATION FUEL CELL FOR THE CONVECTION-FREE TRANSPORT OF FUEL AND METHOD FOR OPERATING THE FUEL CELL
    Publication number: 20090136794
    Abstract: The present invention relates to a direct oxidation fuel cell for the convection-free transport of at least one fuel and also to a method for operating the direct oxidation fuel cell. The principle according to the invention is hereby based on transport of the fluidic fuel from the fuel reservoir to a membrane electrode unit, the transport being effected through a capillary structure using capillary forces and an evaporation suction.
