Embodiment Construction

[0045]The filling station 100 shown by way of non-limiting example is a station arranged for filling the gaseous hydrogen tank 8 at high pressure, for example at a pressure between 300 bar and 850 bar.

[0046] Traditionally, the filling station 100 comprises several buffer containers 1, 2, 3 (three in this non-limiting example).

[0047] Each buffer vessel 1, 2, 3 is a tank or a group of tanks arranged to contain gaseous hydrogen pressurized to a given pressure. The station 100 comprises a fluid circuit 11, 12, 13, 4, 5, 6 comprising a plurality of pipes and valves. This circuit 11 , 12 , 13 , 4 , 5 , 6 is connected to the buffer tank 1 , 2 , 3 . The circuit comprises a first end 4, 5 for connection to at least one source of gaseous hydrogen 14, 15 in order to be able to fill said at least one buffer vessel 1, 2, 3 with gas from at least one source 14, 15.

[0048] The source(s) 14, 15 of hydrogen may conventionally comprise at least one of: a hydrogen network 14 at a press...

Abstract

A method for filling at least one buffer container (1, 2, 3) of a hydrogen filling station (100), the station (100) comprising a fluid circuit (11, 12, 13, 4, 5, 6) linked to said at least one buffer container (1, 2, 3), the circuit of the filling station (100) comprising a first end linked to at least one source of hydrogen gas (14, 15), the circuit (11, 12, 13, 4, 5, 6) comprising a second end provided with a transfer conduit (6) intended to be removably connected to a tank (8), the method being characterised in that it comprises a step (9, 10) of determining the current concentration of at least one impurity in the hydrogen in the buffer container (1, 2, 3) during the filling of same, a step of comparing said current concentration of the impurity relative to a predefined threshold concentration and, when the current concentration of the at least one impurity reaches said threshold concentration, stopping the filling of said buffer container (1, 2, 3).

Description

technical field [0001] The invention relates to a filling method and a filling station. [0002] The invention relates more particularly to a method of filling at least one buffer vessel of a filling station comprising at least one buffer vessel and a fluid circuit connected to said at least one buffer vessel with pressurized gaseous hydrogen, the circuit of said filling station comprising a first end connected to at least one source of gaseous hydrogen for filling said at least one buffer vessel with gas from said source, said circuit comprising a The second end of the delivery pipe for filling the tank from the at least one buffer container. Background technique [0003] Rapid filling (ie typically within 15 minutes) of a vehicle's (hydrogen) gas tank is usually performed by continuous pressure equalization. That is, a buffer vessel storing gas at increased high pressure (eg 200, 300, 450 or 850 bar) is continuously placed in fluid communication with the tank to be fille...
