Patent number: 7431238Abstract: An arrangement and a method are proposed for the generation of water on board an aircraft with the use of one or more fuel cells, whereby low-temperature fuel cells are provided as fuel cells. It is proposed that several single-cell or few-cell fuel cells may form a fuel-cell panel or cell array and several cell panels or cell arrays may be arranged close to the inside of the aircraft fuselage and the cathode side of the at least one fuel cell has a chamber pointing to the exterior of the aircraft for the condensation of the water contained in the air and the anode side has a chamber carrying a combustion gas, for example hydrogen. With the proposed solution, a reduction in the storage capacity for drinking water and its quality-assured provision may be enabled and moreover, with the use of fuel cells as a virtual power station, the energy demand on engine generators, auxiliary power unit (APU) or ram air turbine (RAT) may be reduced.Type: GrantFiled: July 19, 2006Date of Patent: October 7, 2008Assignee: Airbus Deutschland GmbHInventors: Claus Hoffjann, Hansgeorg Schuldzig, Hans-Juergen Heinrich

Publication number: 20060099477Abstract: For operation, PEMFCs require among other things a compressor for the cathode air, and a system for removing the water which is generated on the cathode side as a result of the electrochemical reaction. According to an embodiment of the present invention the removal of water is supported in that the fuel cell is made to rotate by way of an electric motor so that the water contained in the cathodes of the fuel cell can be extracted by centrifugal force. To this effect the air channels on the cathode side are arranged so as to extend radially or in a spiral shape from the inside towards the outside. In this way the efficiency of the fuel cell can be significantly improved.Type: ApplicationFiled: September 13, 2005Publication date: May 11, 2006Applicant: Airbus Deutschland GmbHInventors: Claus Hoffjann, Hansgeorg Schuldzig, Hans-Juergen Heinrich

Publication number: 20060060712Abstract: Drain masts of commercial aircraft need to be heated in order to prevent freezing caused by the low outside temperatures when the aircraft travels at a corresponding altitude. An exemplary embodiment described in the application pertains to a drain system for an aircraft that can be used for draining liquids or gases from the aircraft or for drawing air into the aircraft. In this case, the liquids or gases are heated by means of a coolant that receives its thermal energy from a thermal or electrochemical process being carried out on board the aircraft. Consequently, the waste heat produced by the thermal or electrochemical process being carried out on board the aircraft, for example, a fuel cell process, can be carried off outboard via the drain system. In addition, the coolant can be advantageously utilized for cooling the thermal or electrochemical process.Type: ApplicationFiled: July 26, 2005Publication date: March 23, 2006Inventors: Claus Hoffjann, Hansgeorg Schuldzig, Harald Gruendel, Hans-Juergen Heinrich
