摘要:
The invention relates to a method for operating a direct oxidation fuel cell in which the fuel cell is supplied generally with methanol via a transport device for the fuel. The invention likewise relates to a corresponding arrangement comprising a direct oxidation fuel cell, a fuel reservoir and at least one device for transporting the fuel through the fuel cell.
摘要:
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.

摘要:
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.

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.
摘要:
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.
