Direktoxidationsbrennstoffzelle für den konvektionsfreien Transport des Brennstoffs und Verfahren zum Betreiben der Brennstoffzelle

DE 102006030236 A1 UPAB: 20080220 NOVELTY - The fuel cell has a membrane (2) electrode unit with an anode and cathode, and provided with a fluid distribution structure and a fuel (16) reservoir. The fuel cell has the membrane-electrode unit, where the membrane-electrode unit has a capillary structure, which is connected to a fuel reservoir for the transport of the fuel by evaporation suction. The capillary structure has multiple capillaries, which are arranged parallel to each other. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for operating the direct-oxidation fuel cell. USE - Direct-oxidation fuel cell for a convection-free transport of fluidic fuels (Claimed). ADVANTAGE - The fuel cell has the membrane-electrode unit, where the membrane-electrode unit has a capillary structure, which is connected to a fuel reservoir for the transport of the fuel by evaporation suction, and hence ensures extended temperature range for working of fuel cell, convection-free transport, better performance data and a simpler system engineering, higher temperatures results improved methanol oxidation kinetics
