Abstract: A floor segment for a transportation system, in particular for an aircraft, for the spatial separation of an interior space of the into a lower space and into an upper space. The floor segment has an upper partition and a lower partition, which together with the upper partition encloses a hollow space, which is equipped for accommodating system component of the aircraft. Preferably, the floor segments are of a modular design so that within a floor individual floor segments can be exchanged for other floor segments that comprise identical or compatible dimensions and connections for the system components.

Abstract: A water generation system for the generation of water on board an aircraft comprises a fuel cell device having an exhaust for an exhaust gas, a condenser and an outflow valve for discharging cabin air, which is drawn off through the condenser due to the pressure difference between the cabin pressure and ambient pressure without extensive cooling circuits or pumps, for example. The condenser may be coupled to the exhaust such that the exhaust gas is cooled by cabin air, and the outflow valve is connected to the condenser and to the environment of the aircraft, such that, when the aircraft is at cruising altitude, the cabin air is drawn through the condenser and is discharged into the environment.

Abstract: This application describes a floor segment (11, 13) for a means of locomotion, in particular for an aircraft, for the spatial separation of an interior space of the means of locomotion into a lower space (70) and into an upper space (60). The floor segment (11, 13) comprises an upper partition (81) and a lower partition (82), which together with the upper partition encloses a hollow space (30), which is equipped for accommodating system components (20-29, 32-35) of the means of locomotion. Preferably the floor segments are of a modular design so that within a floor (80) individual floor segments (11, 13) can be exchanged for other floor segments (11, 13) that comprise identical or compatible dimensions and connections for the system components.

Abstract: A water generation system for the generation of water on board an aircraft, in one example, may be used for the cooling of the fuel cell exhaust air cabin air which is drawn off through the condenser due to the pressure difference between the cabin pressure and ambient pressure and may not require extensive cooling circuits or pumps.
