Problems solved by technology
This has the disadvantage of requiring two additional cryogenic tanks and higher hydrogen consumption as the empty intermediate tank must be filled and is hot and under high pressure and must be cooled and depressurized to refill with liquefied hydrogen
[0011] Therefore, the specification of a liquid storage facility for the use of hydrogen at 5 bar for fuel cells can be detrimental to the fill level of the storage facility and its durability

Embodiment Construction
[0041] A device 1 for supplying hydrogen to a fuel cell comprises a fuel cell 2, a liquefied hydrogen storage facility 3 and a supply circuit 4, 14 comprising at least one upstream end connected to the storage facility 3 and a fuel inlet connected to the fuel cell 2 a downstream end of .
[0042] The supply circuit 4 , 14 comprises at least one system 5 , 15 for heating the hydrogen by exchanging heat with a heat source and a set of control valves 6 , 16 , 26 .
[0043] The liquefied hydrogen storage facility 3 is configured to keep the liquefied hydrogen in equilibrium with a gas phase at a relatively low defined nominal storage pressure, eg 1.5 to 4.5 bar.
[0044] The supply circuit 4 , 14 comprises a buffer tank 7 for pressurizing the gaseous hydrogen, which is configured to store hydrogen extracted from the storage facility 3 and heated by the heating system 5 , 15 . The set of valves is configured to accumulate pressurized gas in the surge tank 7 at a relatively high dete...

Installation for supplying a fuel cell with hydrogen comprising a fuel cell, a liquefied hydrogen storage facility and a supply circuit comprising at least one upstream end connected to the storage facility and one downstream end connected to a fuel inlet of the fuel cell, the supply circuit comprising at least one system for heating hydrogen by heat exchange with a heat source and a set of control valve, the liquefied hydrogen storage facility being configured to keep the liquefied hydrogen in equilibrium with a gaseous phase at a determined nominal storage pressure of between 1.5 and 4.5 bar, the supply circuit including a buffer tank for pressurized gaseous hydrogen which is configured to store the hydrogen withdrawn from the storage facility and heated by the heating system, the set of valves being configured to accumulate pressurized gas in the buffer tank at a determined storage pressure of between 4 and 100 bar, for example between 6 and 8 bar. Also disclosed is a method for supplying the fuel cell with hydrogen.
Description
technical field [0001] The invention relates to a device and a method for supplying hydrogen to a fuel cell. [0002] More specifically, the present invention relates to an apparatus for supplying hydrogen to a fuel cell, the apparatus comprising a fuel cell, a liquefied hydrogen storage facility, and a supply circuit comprising at least one upstream end connected to the storage facility and connected to a downstream end of the fuel inlet of the fuel cell, the supply circuit comprising at least one system for heating the hydrogen by heat exchange with a heat source and a set of control valves, the liquefied hydrogen storage facility configured to maintain the liquefied hydrogen in equilibrium with the gaseous phase, The gas phase is at a defined nominal storage pressure of 1.5 bar to 4.5 bar. Background technique [0003] Fuel cells operate with a hydrogen pressure of several hundred millibars at the anode. But fuel cell manufacturers in most cases specify a pressure of 5 ...
