Direct oxidation fuel cell for convection-free transport of the fuel and method for operating the fuel cell

摘要

The present invention relates to a direct oxidation fuel cell for the convection-free transport of at least one fuel and to a method for operating the direct oxidation fuel cell. The inventive principle is based here on a transport of the fluid fuel from the fuel reservoir to a membrane-electrode unit, wherein the transport takes place through a capillary structure by utilizing capillary forces and a Evaporationssoges.
