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.

Method for operating a direct oxidation fuel cell and corresponding arrangement

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.

Direct oxidation fuel cell and method for operation thereof

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