[0079] 1st backflow preventer

[0080] refer to figure 1 , the system 100 may include a first backflow preventer valve 140 . The first anti-reflux valve 140 is for example adapted to allow a flow of hydrogen from the first chamber 110 to the second chamber 120 . The first anti-backflow valve 140 is, for example, adapted to allow hydrogen flow from the first chamber 110 to the second chamber 120 when the pressure in the first chamber 110 exceeds a first cracking pressure. This cracking pressure is appropriate for the intended application.

[0081] Above a certain pressure, hydrogen gas may be transferred from the first chamber 110 to the second chamber 120 .

[0082] The first anti-backflow valve 140 is, for example, a differential pressure valve.

[0083] Secondary Backflow Preventer

[0084] The device 100 may include a second backflow preventer valve 150 .

[0085] The second anti-backflow valve 150 is for example adapted to allow hydrogen flow from the second chamber ...

[0104] fluid communication member

[0105] refer to figure 2 , system 100 may include fluid communication means 122 for flowing hydrogen gas flow from first chamber 110 to second chamber 120 and / or from second chamber 120 to first chamber 110 . The system, eg the fluid communication member 122 is eg configured to maintain the first chamber 110 and the second chamber 120 in fluid communication. The fluid communication member 122 may include or be a fluid communication component.

[0106] Thus, it is possible to integrate the second chamber 120 in the same circuit as the first chamber, the system being configured to function under the conditions (e.g. pressure) e.g. used to operate the first chamber, e.g. 121 at a filling rate of about 50% and between the absorption or adsorption equilibrium pressure and the desorption equilibrium pressure at a selected temperature (eg, 50° C.) of the second chamber. The operating temperature of the second chamber 120 may be the same as that...

Embodiment

[0139] refer to image 3 , which depicts a method for implementing the system 100.

[0140] The method may include a step 1300 for manufacturing or providing the system 100 .

[0141] The method may include a step 1302 for using the system 100 and / or unit. Step 1302 may include step 13020 for controlling the hydrogen pressure of the first chamber as described above.

[0142] The method may include a step 1304 for increasing the hydrogen pressure of the first chamber. This increase in hydrogen pressure can have many causes, such as an increase in temperature. The method may include the sequential step 1306 of transferring hydrogen to the second chamber to limit the hydrogen pressure within the first chamber and / or trap the hydrogen through the material 121 . This second step 1306 is performed, for example, by means of the first anti-backflow valve 140 , supplemented by, for example, the second anti-backflow valve 150 .

[0143] The method may include a step 1308 of reducin...

Abstract

The invention relates to a system (100) for using and / or producing hydrogen, the system comprising: a unit comprising a first chamber (110) suitable for containing hydrogen; and means for controllingthe pressure of the hydrogen in the first chamber, the means comprising a second chamber (120) suitable for storing hydrogen, the second chamber containing a material (121) for the reversible storageof hydrogen by sorption, the first chamber and the second chamber being arranged so that the material (121) captures and / or releases hydrogen by sorption, in such a way as to limit and / or stabilize the hydrogen pressure in the first chamber (110).

Description

technical field [0001] The invention relates to a hydrogen utilization system. The invention also relates to related methods. Background technique [0002] There are currently a variety of hydrogen utilization systems. These systems can use hydrogen to generate electricity, participate in chemical processes, store hydrogen, enable vehicles to move and / or provide electricity to mobile systems, i.e., devices that are especially suitable for movement due to their mass and their volume, such as portable devices, such as A device that recharges or supplies energy to devices such as mobile phones. [0003] These systems must comply with multiple constraints related to their intended use, such as storage at variable ambient temperatures (eg, relatively low ambient temperatures), such as those used in motor vehicles and / or to supply electrical power to fuel cells, or multiple restrictions on specific conditions of use. [0004] Therefore, acceptable pressures and sufficient velo...
