Embodiment Construction

[0028] figure 1 is implemented on an aircraft according to the present invention and is figure 2 A schematic diagram of the apparatus 100 shown schematically in FIG.

[0029] The device 100 includes a fuel cell 102 that converts chemical energy from the redox of hydrogen and oxygen molecules into electrical energy, heat, and water. To this end, the aircraft 200 includes a hydrogen molecule tank and a circuit loop that ensures the supply of hydrogen molecules to the fuel cell 102 . Likewise, the fuel cell 102 is also supplied with oxygen molecules, which may come from the oxygen molecule tank of the aircraft 200, or by outside air. Such architectures are conventional and will not be described further.

[0030] figure 2 is a schematic diagram of aircraft 200 including structure 202 and engines 204 .

[0031] The structure 202 generally includes a fuselage 206 and wings 208 on either side of the fuselage 206 . The aircraft 200 here includes two engines 204 under each win...

Abstract

The invention relates to an aircraft comprising: a structure (202) comprising a leak-proof tank (210) delimited by walls, at least one of which is in contact with the air outside the aircraft, the leak-proof tank being partially filled with a two-phase heat transfer fluid; a fuel cell (102) through which the heat transfer fluid passes; and a conduit (106) that receives the heat transfer fluid at the output of the fuel cell (102) and reintroduces the heat transfer fluid at the input of the fuel cell (102). The conduit (106) passes through the leak-proof tank (210) in the form of immersion in a heat transfer fluid in the liquid phase. This arrangement avoids the necessity of installing a large-sized heat exchanger.

Description

technical field [0001] The present invention relates to an aircraft comprising at least one fuel cell and a structure with a tank allowing storage of a two-phase heat transfer fluid ensuring cooling of said fuel cell. Background technique [0002] In order to reduce the fuel consumption of aircraft, it is known to use fuel cells, wherein each fuel cell generates an electrical current that is used to power an electric motor that turns one or more propellers. [0003] Fuel cells make it possible to convert chemical energy from the redox reactions of hydrogen and oxygen molecules into electricity, heat and water. [0004] In order to control the temperature of the fuel cell, such a device includes a cooling system. [0005] Figure 4 is a schematic diagram of such a device 400 on an aircraft, which includes a fuel cell 402 and a cooling system 404 that includes a line 406 that receives a heat transfer fluid at the output of the fuel cell 402 and that runs at the fuel cell 402 ...
