- the driver can then easily choose the path that corresponds to the desired power.
- control means is also suitable for controlling the flow of fuel supplying the system, as a function of the chosen route or routes.
- the method for supplying hydrogen to a motor vehicle fuel cell uses a fuel reforming process with hydrogen enrichment of the reformate and purification of the reformate by reaction of carbon monoxide. carbon. Furthermore, the flow of hydrogen supplied to the fuel cell is controlled, as a function of the desired power, by using one or more individual reforming paths.
- FIG. 1 shows the main elements of a traction chain of a motor vehicle, comprising a fuel reforming system and a fuel cell;
- FIG. 2 shows a first embodiment of a reforming system according to the invention, with two separate complete channels;
- FIG. 3 illustrates a second embodiment of a reforming system according to the invention, with two partial paths joining in a single path;
- FIG. 4 illustrates a third embodiment of a reforming system according to the invention, with two partial channels joining in a single channel;
- FIG. 5 illustrates a variant of the embodiment of FIG. 4.
- a reforming system 1 supplies hydrogen to a fuel cell 2 through the pipe 3.
- the electric current produced by the fuel cell 2 is supplied to a converter 4 connected to the fuel cell 2 by the electrical connection 5.
- An electrical connection 6 connects the converter 4 to the power battery 7 which equips the vehicle.
- the electric current from the converter 4 is brought by the electrical connection 8 to the electric motor 9 of the vehicle, connected by the shaft 10 to the transmission and to the wheels of the vehicles shown diagrammatically by the block 11.
- a fuel tank 12 is equipped with a pump 13 capable of supplying fuel via the line 14 to the reforming system 1.
- the air is supplied by the line 15 to a compressor 16 before being led by the lines 17 and 18, respectively in the fuel cell 2 and in the reforming system 1.
- An electronic control unit 19 is capable of sending control signals to the fuel pump 13 by the connection 20 and to the reforming system 1 by the connection 21, so as to control the latter, as will be seen below. .
- a power indicator device 22 receives via the connection 23 a signal from the electronic control unit 19, so as to warn the driver of the power available for the traction motor. Also shown in Figure 1 is a mode selection button 24 connected by connection 25 to the electronic control unit 19, and an anti-theft contactor device 26, also connected by connection 27 to the electronic control unit . It will be understood, of course, that other means could be provided, the means described being so only by way of example.
- the control unit In operation, when the electronic control unit has received a signal from the anti-theft switch 26 and from the mode selection button 24, the control unit is able to control the pump 13 to supply the reforming system 1.
- This ci suitably heated by means which are not shown in FIG. 1, and supplied with compressed air by the compressor 16, produces a reformate rich in hydrogen, suitably purified, as will be seen below, so as to supply the battery fuel 2.
- An excess part of the hydrogen returns to the reforming system 1 via line 28.
- the vehicle equipped with these different means must be capable, as is the case with a vehicle fitted with a heat engine, of adapting as well to urban use where the average power consumed by the traction chain is low, than for road or motorway use where the average power consumed is on the contrary high.
- the object of the present invention is to allow these two types of use by reducing consumption, so as to ensure operation comparable to that of a conventional vehicle but with the advantages which are attached to electric traction.
- FIG. 2 illustrates a first embodiment of the invention, in which the reforming system 1 comprises two channels, each comprising the same components.
- the two channels, a and b, are placed in parallel.
- Each of them comprises a reformer device 29a, 29b, a high temperature hydrogen enrichment device 30a, 30b, a second lower temperature hydrogen enrichment device 31a, 31b, and a purification device 32a, 32b, reaction of carbon monoxide in the reformate produced.
- the optimal operating temperature of each of these devices is ensured by heat exchangers referenced 33a, 33b, 34a, 34b, 35a, 35b.
- a burner 36 produces heat energy which is brought to a heat exchanger 37 receiving air coming from the pipe 18.
- the hot air leaving the exchanger 37 passes through the reactors 29, 30, 31 and 32, thus allowing to heat them. Gases from combustion from the burner 36 also pass through the various heat exchangers 33, 34 and 35, after having passed through the heat exchanger 37.
- the double supply of heat reduces the heating time of the installation.
- the exchanger 37 is used to vaporize the fuel supplied by the line 14 and the water supplied by the line 38.
- the fuel and the water vaporized in the heat exchanger 37 can be brought into the one or the other of the channels a, b, or in the two channels simultaneously, depending on the position of a valve 39 controlled by a signal from the electronic control unit 19, visible in FIG. 1.
- the two paths a and b meet at the inlet of the fuel cell 2, the gaseous mixture rich in hydrogen being brought to the appropriate temperature by passage through a heat exchanger 40.
- the different components of the devices of one of the channels will be chosen, for example channel a, so as to provide a power, for example of the order of 60 kW, while the components of the devices of channel b will be chosen, so as to provide a lower power, for example of the order of 20 kW.
- the driver When starting the vehicle, the driver then has a choice between two operating modes:
- the driver can privilege consumption, by only putting into action at start-up that channel b of a lower power, of the order of 20 kW. The amount of fuel consumed to warm up the reforming system is then reduced.
- the driver can favor the performance of the vehicle, by then activating the two tracks a and b, simultaneously, from the start of the vehicle. it however, requires heating all the devices of the two channels a and b simultaneously, which results in a significant increase in the consumption of the vehicle. However, the driver then has, at the end of the warm-up, all of the power installed in the vehicle.
- the interface allowing the driver to choose the operating modes can be, as in the example illustrated, a simple mode selection button, referenced 24 in FIG. 1.
- the power indicator 22 controlled by the electronic control unit 19, signals to the driver the channels which are operational, so that the driver can adapt his driving to the available power.
- the operating logic of this embodiment is as follows:
- the electronic control unit continuously scans the position of the anti-theft switch 26 or of the powertrain start button. As soon as the anti-theft switch 26 or the start button takes the "start" position, the electronic control unit tests the position of the mode selection button 24.
- the electronic control unit activates the burner 36 and adapts the fuel flow by acting on the pump 13 to supply the burner 36 in order to heat the path b of the reforming system, c ' that is to say the path of smaller power.
- the electronic control unit activates the burner and adapts the fuel flow supplying the burner 36, so as to allow the heating of the two channels a and b.
- the electronic control unit ensures the generation of electrical power by the fuel cell as a function of the driver's request, for example as a function of the position of the accelerator.
- the total electrical power available depends, in addition to the mode selected by the driver, on the energy management adopted for the vehicle which can be programmed in the electronic control unit.
- only channel b of the reforming system produces hydrogen which supplies the fuel cell 2.
- the power supplied by the battery is added to the power generated by the fuel cell 2, at provided that the vehicle speed does not exceed the speed which can be reached with the power supplied only by battery 2 supplied with hydrogen by channel b, this speed being less than the maximum vehicle speed which can be reached when the battery is supplied with H 2 by the two channels a and b.
- Such energy management makes it possible to have, for accelerations, the power of the battery in addition to the power of the cell supplied with hydrogen only by one of the channels.
- the power supplied by the battery is not continuously used, since the speed of the vehicle is limited to that which can be achieved with the production of H 2 from the single channel b.
- the electronic control unit is then capable of activating the burner 36 and of adjusting the fuel flow by acting on the pump 13, so as to supply the burner to heat the second channel a of the reforming system, while the first channel b is already at the optimum operating temperature.
- the power indicator 22 informs the driver of the available power.
- the power indicator 22 informs the driver that only the battery is able to supply power. If the mode favoring low consumption is chosen, the indicator informs the driver, as soon as channel b is hot, that only the battery and one of the reformer's channels are available. If the mode favoring performance is chosen, the indicator informs the driver as soon as the two lanes of the reformer are at operating temperature, that the full power of the vehicle is available.
- FIG. 3 illustrates another embodiment, in which the same elements have the same references and / or only the reformer device is duplicated.
- the two channels a and b which each include a reformer device 29a and 29b.
- the two channels a and b join in a single channel at the output of the reformer devices 29a and 29b.
- the single channel then comprises a single hydrogen enrichment device at high temperature, referenced 30, a single hydrogen enrichment device at low temperature, referenced 31, and a single purification device 32.
- the same exchangers 33 are found, 34, 35 and 40 as in the embodiment illustrated in FIG. 2.
- the channels a and b each comprise a reformer device 29a, 29b, a high temperature enrichment device 30a, 30b, and a low temperature enrichment device 31a, 31b, the heat exchangers 33a, 33b, 34a, 34b allowing the optimal heating of the various components.
- the two channels a and b meet in a single channel at the outlet of the enrichment device 31a, 31b.
- the purification device 32 is therefore common to the two channels a and b.
- the low temperature enrichment device 31 is also common to the two channels a and b, which each include a reformer device 29a,
- the present invention allows the driver to choose for city driving, operation of the vehicle with reduced consumption in return for a temporary reduction in vehicle performance.
- the choice of the vehicle's operating mode remains under the driver's control, who can at any time switch from an economic mode with low consumption to a mode promoting performance and corresponding to the totality of the power installed on board the vehicle.
