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.

What is claimed is: 1. An arrangement for generating water in an aircraft, the aircraft having a fuselage skin, the arrangement comprising: a plurality of low-temperature fuel cells wherein the plurality of fuel cells form at least one of a fuel-cell panel and a cell array; wherein the at least one of the fuel-cell panel and the cell array is curved and arranged close to an inside of the fuselage skin of the aircraft; wherein a cathode side of at least one fuel cell of the plurality of fuel cells has a first chamber arranged towards an outside of the aircraft, the chamber being for the condensation of the water contained in air; and wherein an anode side of the at least one fuel cell of the plurality of fuel cells has a second chamber for combustion gas. 2. The arrangement according to claim 1, further comprising: a water collection tank; and piping systems; wherein the piping systems are arranged for supplying the combustion gas and atmospheric oxygen and for discharging condensate, outlet air and residual gas; and wherein at least a portion of the piping systems is arranged for discharging water; and wherein the at least one portion of the piping systems is connected to the water collection tank. 3. The arrangement according to claim 1, wherein the at least one of the fuel-cell panel and the cell array is an encapsulated system which prevents a media being supplied and discharged from being released to a passenger cabin of the aircraft or to an outside of the aircraft. 4. The arrangement according to claim 1, wherein a plurality of cell arrays are provided and wherein the plurality of cell arrays are arranged to form a cell matrix. 5. The arrangement according to claim 1, wherein the at least one of the fuel-cell panel and the cell array is adapted for an arrangement close to the fuselage skin between a stringer and an interior cabin lining of the aircraft; whereby a width the at least one of the fuel-cell panel and the cell array is adapted to a spacing of ribs of the aircraft; and wherein the at least one of the fuel-cell panel and the cell array is suitably curved to adapt to a curvature of the fuselage skin of the aircraft. 6. The arrangement according to claim 1, wherein the at least one of the fuel-cell panel and the cell array is strip-shaped such that strips are formed; wherein the strips are arranged side by side; and wherein fuel cells in each of the strips arranged beside one another are arranged such that they are capable of being switched on and off independently of one another. 7. The arrangement according to claim 1, further comprising: connection elements for connection to media-carrying lines; wherein the connection elements are arranged as gas-tight rapid-action couplings. 8. The arrangement according claim 7, wherein a safety valve is provided in at least one of the connection elements of the media-carrying lines, which is arranged, with a sudden drop in pressure, close to supply lines and discharge lines for the respective one of the fuel-cell panel and the cell array panel. 9. The arrangement according to claim 1, wherein the aircraft has an overall matrix; wherein, in the aircraft overall matrix, the at least one of the fuel-cell panel and the cell array is connected electrically partially in parallel and partially in series, so that a ratio between current intensity and voltage that is optimum for operation in aircraft is established. 10. The arrangement according claim 1, further comprising a heat carrier; wherein a temperature on the cathode side is controllable in order to prevent a freezing of condensed water during operation of at least one cell, whereby a temperature equalization takes place between the anode side and the cathode side of the at least one cell, and wherein the temperature equalization takes place via a heat conduction of the heat carrier. 11. The arrangement according to claim 10, wherein the temperature equalization between the cathode and the anode side is controllable such that water contained in the cathode exit-air is condensed. 12. The arrangement according to claim 1, wherein there is a direct thermal contact between an outer skin of the aircraft and the fuel-cell panel. 13. The arrangement according to claim 1, wherein a thermal insulation is provided between an outer skin of the aircraft and the fuel-cell panel. 14. The arrangement according to claim 1, wherein several fuel-cell panels are arranged on an outer skin of the aircraft; wherein an arrangement of the several fuel cell panels is in consideration of an optimum weight distribution.
