a second space defined within the inner shell for holding fuel to be supplied to the at least one fuel cell system component,
wherein the fuel cell system module connects, by a fastening device which is designed to fasten the fuel cell system module releasably to an aircraft structure, modularly to the fuselage section of the aircraft in such a manner that at least a portion of the outer shell forms a partial section of the outer skin of the fuselage section when the fuel cell system module is connected to the fuselage section of the aircraft.
2. The fuel cell system module according to claim 1 , further comprising:
a fuel cell system housing, and
at least one of peripheral components of the fuel cell system and a fuel cell.
3. The fuel cell system module according to claim 2 , wherein the fuel cell system housing and the fuel tank housing are connected along a separating wall such that the fuel cell system housing defines a first partial portion of the outer skin of the fuselage section and the outer shell of the fuel tank housing defines a second partial portion of the outer skin of the fuselage section when the fuel cell system module is connected to the fuselage section of the aircraft.
4. The fuel cell system module according to claim 1 , wherein the fuel tank is designed to store hydrogen gas under elevated pressure.
5. The fuel cell system module according to claim 2 , wherein the fuel cell system housing is designed to form a section of the outer skin of the fuselage section when the fuel cell system module is connected to the fuselage section of the aircraft, and wherein the fuel cell system housing accommodates the at least one of the peripheral components of the fuel cell system and the fuel cell.
6. The fuel cell system module according to claim 1 , wherein the fuel cell system module is formed as a tail boom which is connectable modularly to the fuselage section of the aircraft.

a plurality of fuel cell system modules according to claim 1 , and the plurality of fuel cell system modules being equipped with fuel tanks of different capacities.
8. Use of a fuel cell system module according to claim 1 on an aircraft, comprising:
connecting the fuel cell system module to a fuselage section of the aircraft with a fastening device such that the fuel cell system module is modular and releasable; and
forming a section of an outer skin of the aircraft with the outer shell of the fuel tank housing after connecting the fuel cell system module to the fuselage section.
9. The fuel cell system module according to claim 1 , wherein the outer shell of the fuel tank housing is composed of a rigid material such that the partial section of the outer skin formed by the outer shell is also composed of a rigid material when the fuel cell system module is connected to the fuselage section of the aircraft.
10. An air travel system, comprising:
an aircraft having a fuselage section having an outer skin;
a fuel cell system module releasably connected to the fuselage section to form a tail boom for the aircraft, the fuel cell system module comprising:
at least one fuel cell system component including a fuel cell system housing and at least one of a fuel cell and peripheral components of the fuel cell system, and
a fuel tank having a fuel tank housing, wherein the fuel tank housing comprises:
an outer shell composed of a rigid material,
an inner shell spaced apart from the outer shell,
a first space located between the outer shell and the inner shell of the fuel tank housing and being filled with a material of poor thermal conductivity, and
a second space defined within the inner shell for holding fuel to be supplied to the at least one fuel cell system component,
wherein the fuel cell system module connects, by a fastening device which is designed to fasten the fuel cell system module releasably to an aircraft structure, modularly to the fuselage section of the aircraft,
wherein the fuel cell system housing and the fuel tank housing are connected along a separating wall such that the fuel cell system housing defines a first partial portion of the outer skin of the fuselage section and the outer shell of the fuel tank housing defines a second partial portion of the outer skin of the fuselage section when the fuel cell system module is connected to the fuselage section of the aircraft.
