Description

Technical Field

[0001] The present application relates to a hydrogen fuel cell system, which may also be referred to as a hydrogen power module, and in particular to a hydrogen power module anode subsystem of the hydrogen power module. Background Art

[0002] As an important technical route in new energy vehicles, hydrogen fuel cell systems (hydrogen power modules) can be used as an energy source to power vehicles and are widely used. This hydrogen power battery generates water through the electrochemical reaction of hydrogen and oxygen in the stack (reactor), thereby providing electrical energy that can be used by the vehicle. Because oxygen is widely present in the air, and the product of the reaction process as described above is water, this will not only not cause ecological pollution but is very environmentally friendly. At least for this reason, this hydrogen power battery route has broad development prospects.

[0003] In this hydrogen fuel cell system, an anode subsystem is equipped to provide hydrogen to the stack (specifically, the anode side of the stack). However, the existing anode subsystem still has some problems. For example, in the process of providing hydrogen, due to some unavoidable reasons in actual use, overpressure often occurs at the interface between the anode subsystem and the stack. This overpressure can cause very adverse effects. For example, it may cause hydrogen leakage, and even cause excessive pressure on the interface itself, the anode subsystem, and the stack, causing deformation or even rupture, so it is not desired. The hazards caused include but are not limited to pressure imbalance in the system, and even combustion or explosion related to hydrogen.

[0004] The solution currently adopted in the prior art is to use an overpressure relief valve to release the hydrogen gas that causes the overpressure to the outside through the overpressure relief valve, thereby releasing the pressure. However, this solution still has some defects.

[0005] For example, the speed at which this hydrogen overpressure is generated and accumulated is very fast. In contrast, the response speed of the overpressure relief valve is relatively slow. This mismatch may cause serious lag in the pressure relief operation and / or the pressure relief process takes too long, causing the response component to bear the overpressure for more than the threshold time, and the safety risk cannot be eliminated in a timely and effective manner. For another example, the current hydrogen power module anode subsystem is basically electronically controlled, however, this overpressure relief valve is often mechanical. This mismatch cannot be effectively integrated into the entire hydrogen power module anode subsystem. This affects the response efficiency and control efficiency of the entire system. In addition, the space cost and economic cost of this mechanical overpressure relief valve are very high. Equipping each hydrogen power module anode subsystem with this mechanical overpressure relief valve will affect the space efficiency of the hydrogen power module and significantly increase the economic cost of the entire hydrogen power module. This is also not expected.

[0006] In view of but not limited to the above-mentioned various problems, it is desirable to provide a novel hydrogen power module anode subsystem to at least alleviate or even solve the above-mentioned problems. Summary of the Invention

[0007] The present application aims to provide a hydrogen power module anode subsystem, which is advantageous in at least one aspect over the prior art.

[0008] To this end, the present application provides, in one aspect, a hydrogen power module anode subsystem, which is configured to transfer hydrogen stored in a hydrogen storage tank into a hydrogen power module reactor and includes: a shut-off valve, which is configured to control the supply of hydrogen from the hydrogen storage tank; a hydrogen injection valve, which is configured to adjust the pressure of the hydrogen; and a first pressure sensor arranged at the inlet port on the anode side of the hydrogen power module reactor, wherein the hydrogen power module anode subsystem is configured to, via a hydrogen power module controller, close the shut-off valve and the hydrogen injection valve when a first pressure indication detected by the first pressure sensor generates an overpressure, thereby controlling (e.g., alleviating or even eliminating) the overpressure generated by the hydrogen at the inlet port.

[0009] In another aspect, the present application also provides a hydrogen fuel cell system (hydrogen power module). This hydrogen power module includes: a hydrogen storage tank; the hydrogen power module anode subsystem described above; and a hydrogen power module reactor; wherein the hydrogen power module anode subsystem is configured to transfer hydrogen stored in the hydrogen storage tank to the hydrogen power module reactor to generate electricity.

[0010] In yet another aspect, the present application further provides a vehicle, which includes the hydrogen fuel cell system (hydrogen power module) described above.

[0011] The hydrogen power module anode subsystem according to the present application can omit, or even eliminate, a (mechanical) overpressure relief valve. This saves space for the anode subsystem and even the entire hydrogen power module, allowing the hydrogen power module including the anode subsystem to be arranged in a vehicle in a more space-efficient manner, thereby improving the integration of the hydrogen power module and the entire vehicle.

[0012] Furthermore, the hydrogen power module anode subsystem disclosed in this application can quickly respond to overvoltage from the moment it begins, ensuring timely response and efficient control. Furthermore, this hydrogen power module anode subsystem can fully utilize electronic control methods without relying on mechanical components to establish a direct and effective response and treatment for overvoltage issues.

[0013] As can be seen from the above, the hydrogen power module anode subsystem disclosed in this application can provide a more advanced hydrogen overpressure solution without adding additional hardware. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 2 The relationship between the pressure threshold and the maximum pressure threshold that can be supported according to an exemplary embodiment of the present application is shown.

[0016] Figure 3 A method for a hydrogen power module anode subsystem according to an exemplary embodiment of the present application is shown. DETAILED DESCRIPTION

[0017] The following describes some possible exemplary embodiments of the present application with reference to the accompanying drawings. It should be noted that the drawings are not drawn to scale. Some details may be enlarged for clarity, and some non-essential details may be omitted.

[0018] like Figure 1 , an exemplary embodiment of a hydrogen power module anode subsystem 100 for a hydrogen fuel cell system (hydrogen power module) disclosed in the present application is shown.

[0019] The hydrogen power module anode subsystem 100 is configured to be able to transfer hydrogen stored in a hydrogen storage tank (not shown) to the hydrogen power module reactor, specifically the anode stack 200 of the hydrogen power module reactor. Thus, the hydrogen and oxygen also sent thereto undergo an electrochemical reaction in the hydrogen power module reactor via a catalyst (often implemented as a proton exchange membrane) to synthesize water. In this way, electrical energy is generated. This electrical energy generated at the reactor is then transferred to a high-voltage battery (not shown) located downstream to store the electrical energy. Thus, when needed, the electrical energy can be provided to power and / or other suitable components of the vehicle.

[0020] The hydrogen power module anode subsystem 100 includes a stop valve 1. Stop valve 1 controls the supply of hydrogen. When stop valve 1 is open, hydrogen flows from the upstream hydrogen storage tank to the downstream side of stop valve 1 and is supplied to the hydrogen power module reactor. When stop valve 1 is closed, stop valve 1 cuts off the hydrogen supply from the hydrogen storage tank. The opening and closing of stop valve 1 can be controlled by the hydrogen power module controller (FCCU) 300.

[0021] The hydrogen power module anode subsystem 100 may further include a hydrogen heat exchanger 2. The hydrogen heat exchanger 2 is configured to adjust (increase and / or decrease) the temperature of the hydrogen from the hydrogen storage tank to a suitable temperature value or temperature range. Such a temperature value or temperature range may be pre-set and / or depend on the surrounding environment, such as the operating environment of the vehicle and / or battery. The hydrogen heat exchanger 2 may be disposed upstream of the shut-off valve 1 (e.g., Figure 1As shown). In this way, the shut-off valve 1 can be protected from the effects of excessively high or low hydrogen temperatures, thereby extending the service life of the shut-off valve 1. It can also be known that the hydrogen heat exchanger 2 can also be arranged downstream of the shut-off valve 1 (not shown). The advantage of this is at least that the hydrogen supply from the hydrogen storage tank can be more conveniently controlled. In this way, even if the temperature of the hydrogen itself is too high or too low in the storage tank due to some reasons (such as due to the external ambient temperature), the temperature of the hydrogen in the hydrogen power module anode subsystem 100 can be adjusted to a suitable temperature, protecting the entire hydrogen power module anode subsystem and even the safety and stability of the use of the hydrogen power module reactor. In an exemplary embodiment, the control and / or regulation of the hydrogen heat exchanger 2 can be configured to be associated with the hydrogen power module controller 300. Alternatively or additionally, the control and / or regulation of the hydrogen heat exchanger 2 can be configured to, for example, a pre-set fixed value or range, or be associated with a detection device (such as a temperature sensor) for detecting the hydrogen storage tank or the hydrogen therein.

[0022] The hydrogen power module anode subsystem 100 may further include a temperature sensor: a primary temperature sensor 3. The primary temperature sensor 3 is arranged downstream of the hydrogen heat exchanger 2 to detect whether the hydrogen is adjusted to a suitable temperature value or range by the hydrogen heat exchanger 2.

[0023] The hydrogen power module anode subsystem 100 further includes a hydrogen supply module 30, such as a compact hydrogen supply module (HSM-C). The hydrogen supply module 30 is arranged downstream of the shutoff valve 1 and the hydrogen heat exchanger 2 and is configured to regulate the pressure and flow of hydrogen, thereby supplying hydrogen to the hydrogen power module reactor at an appropriate pressure and flow rate.

[0024] A pressure sensor (primary pressure sensor) 4 may be disposed upstream of and adjacent to the hydrogen supply module 30. Based on the hydrogen pressure detected by the pressure sensor 4, the hydrogen supply module 30 may adjust the hydrogen pressure to meet the requirements of the hydrogen power module reactor.

[0025] Specifically, the hydrogen supply module 30 includes a hydrogen injection valve (HGI) 6. The hydrogen injection valve 6 is configured to adjust the pressure and / or flow rate of hydrogen. The hydrogen injection valve 6 can be associated with the FCCU 300. For example, the FCCU 300 controls the hydrogen injection valve 6 to adjust the hydrogen pressure and / or flow rate.

[0026] Since hydrogen is stored at high pressure in the hydrogen storage tank, this high pressure is not desirable for the hydrogen power module reactor. Therefore, it is often necessary to depressurize the hydrogen through the hydrogen injection valve 6 so that the pressure of the hydrogen drops to a suitable pressure range, so that on the one hand, hydrogen can be supplied to the hydrogen power module reactor at a sufficient rate, and on the other hand, this pressure of hydrogen will not adversely affect the associated components including the hydrogen power module reactor (for example, deformation, rupture and / or destruction). It can be understood that this suitable pressure range can be predetermined. In addition, the flow rate of hydrogen supplied to the hydrogen power module reactor needs to be controlled within a suitable value or range. This can also be controlled by the hydrogen injection valve 6; additionally, the pressure can also be controlled by the jet pump 7 located downstream of the hydrogen injection valve 6.

[0027] In the present application, the hydrogen supply module 30 is configured to supply hydrogen to the hydrogen power module reactor 200 located downstream thereof, and the overpressure relief valve and even the bypass line associated therewith located between the hydrogen supply module 30 and the hydrogen power module reactor 200 used in the prior art can be omitted (or even excluded).

[0028] Hydrogen flows directly from the hydrogen supply module 30 into the anode side of the hydrogen power module reactor via the inlet port 201. Most of the hydrogen reacts on the anode side to produce water, while the remaining small portion of hydrogen, along with the water, flows out of the anode side of the hydrogen power module reactor via the outlet port 202. This small portion of hydrogen undergoes primary separation from the product water at the water separator 13. The water that has undergone primary separation is discharged as water vapor via the drain valve 14 and the first heating unit 17. After secondary separation at the water separator 13, this small portion of hydrogen is completely separated from the product water. The water that has undergone this secondary separation is discharged as water vapor via the exhaust valve 15 and the second heating unit 16.

[0029] The remaining small portion of hydrogen after secondary separation is pumped back to the jet pump 7 via the hydrogen circulation pump 18. Via the jet pump 7, the remaining small portion of hydrogen is merged into the hydrogen flow and is supplied to the anode side of the hydrogen power module reactor again.

[0030] A temperature detection device (first temperature sensor 8) and a pressure detection device (first pressure sensor 9) are provided at the inlet port 201 on the anode side of the hydrogen power module reactor. The first temperature sensor 8 is configured to detect the temperature (first temperature) of the hydrogen gas entering the anode side of the hydrogen power module reactor. Similarly, the first pressure sensor 9 is configured to detect the pressure (first pressure) of the hydrogen gas entering the anode side of the hydrogen power module reactor. The first temperature sensor 8 and / or the first pressure sensor 9 are also configured to be communicatively connected to the FCCU 300. In this way, the first temperature detected by the first temperature sensor 8 and / or the first pressure detected by the first pressure sensor 9 can be transmitted to the FCCU 300. The FCCU 300 can (for example, immediately) close the shut-off valve 1 and / or close the hydrogen injection valve 6 based on the indication of overpressure represented by the first temperature and / or first pressure of the hydrogen gas entering the anode side of the hydrogen power module. In this way, on the one hand, the subsequent supply of hydrogen to the anode side of the hydrogen power module reactor can be cut off, and on the other hand, the hydrogen previously remaining in the hydrogen power module anode subsystem 100 can flow into the anode side of the hydrogen power module within a limited time, so that the hydrogen in the hydrogen power module anode subsystem can be cleared in a shorter time, thereby eliminating the overpressure condition at the inlet port 201 of the hydrogen power module reactor.

[0031] Additionally, a second temperature sensor 10 and a second pressure sensor 11 may be provided at the discharge port 202 on the anode side of the hydrogen power module reactor. The second temperature sensor 10 is configured to detect the temperature (second temperature) of the hydrogen gas discharged from the anode side of the hydrogen power module reactor. Similarly, the second pressure sensor 11 is configured to detect the pressure (second pressure) of the hydrogen gas discharged from the anode side of the hydrogen power module reactor. The second temperature sensor 10 and / or the second pressure sensor 11 are also configured to be communicatively connected to the FCCU 300 (not shown). Therefore, the second temperature detected by the second temperature sensor 10 and / or the second pressure detected by the second pressure sensor 11 can be transmitted to the FCCU 300. The FCCU 300 can further close the shut-off valve 1 and / or the hydrogen injection valve 6 (for example, immediately) based on an indication of overpressure (represented by the second temperature and / or second pressure). In this way, the technical effects described above can be further enhanced, and will not be described in detail here.

[0032] In an exemplary embodiment, the FCCU 300 may control the shutoff valve 1 and / or the hydrogen injection valve 6 based on the first pressure and / or the second pressure. For example, when the first pressure is higher than a predetermined first pressure threshold, the shutoff valve 1 and / or the hydrogen injection valve 6 are closed. In this case, the difference (pressure drop) between the second pressure and the first pressure may optionally be considered. For another example, when the second pressure is higher than a predetermined second pressure threshold, the shutoff valve 1 and / or the hydrogen injection valve 6 are closed. For another example, when the first pressure is higher than a predetermined first pressure threshold and the second pressure is higher than a predetermined second pressure threshold, the shutoff valve and / or the hydrogen injection valve 6 are closed. The first pressure threshold may be associated with the second pressure threshold. For example, the first pressure threshold may be greater than the second pressure threshold.

[0033] In an exemplary embodiment, the FCCU 300 closes the stop valve 1 and / or the hydrogen injection valve 6 only when the first pressure exceeds a first pressure threshold for a predetermined time period. This approach avoids unnecessary overpressure indications caused by temporary pressure fluctuations. Such temporary pressure fluctuations resolve themselves within a short period of time, eliminating the need for the FCCU 300 to close the stop valve 1 and / or the hydrogen injection valve 6.

[0034] Similarly, and in addition, the correlation between temperature and pressure can be utilized to further detect the generation of overpressure through temperature. For example, FCCU 300 can control shutoff valve 1 and / or hydrogen injection valve 6 based on the first temperature and / or the second temperature. For example, if the first temperature is higher than a predetermined first temperature threshold, shutoff valve 1 and / or hydrogen injection valve 6 are closed. For another example, if the second temperature is higher than a predetermined second temperature threshold, shutoff valve 1 and / or hydrogen injection valve 6 are closed. The first temperature threshold can be associated with the second temperature threshold. For example, the first temperature threshold can be (substantially) the same as the second temperature threshold; alternatively, the second temperature threshold can be lower than the first temperature threshold.

[0035] In an exemplary embodiment, the FCCU 300 closes the shutoff valve 1 and / or the hydrogen injection valve 6 only when the first temperature exceeds the first temperature threshold for a predetermined time period.

[0036] In one exemplary embodiment, the shutoff valve 1 can be closed first, and then the hydrogen injection valve 6 can be closed after a predetermined time. The predetermined time period is correlated with the time required for hydrogen to flow from the shutoff valve 1 through the hydrogen injection valve 6. In this way, the hydrogen between the shutoff valve 1 and the hydrogen injection valve 6 can be effectively discharged, preventing the formation of hydrogen residue or overpressure in this section. This further enhances the functional safety of the entire hydrogen power module anode subsystem 100. In another exemplary embodiment, the shutoff valve 1 and the hydrogen injection valve 6 can be closed simultaneously.

[0037] In an exemplary embodiment, when the shutoff valve 1 and the hydrogen injection valve 6 are closed, the FCCU 300 can be configured to lock the entire hydrogen power module anode subsystem 100, thereby preventing the shutoff valve 1 and the hydrogen injection valve 6 from being reopened. In this manner, after the shutoff valve 1 and the hydrogen injection valve 6 are closed and before the entire hydrogen power module anode subsystem 100 is inspected and maintained, the shutoff valve 1 or the hydrogen injection valve 6 can be prevented from being opened automatically or manually (due to, for example, user error), thereby further improving the functional safety of the hydrogen power module anode subsystem 100.

[0038] Additionally, the FCCU 300 may also consider the primary temperature sensor 3 and / or the primary pressure sensor 4 when controlling the shutoff valve 1 and / or the hydrogen injection valve 6 .

[0039] Optionally, when the shutoff valve 1 and / or the hydrogen injection valve 6 are closed, the injection pump 7 and / or the hydrogen circulation pump 18 may also be shut down (e.g., via the FCCU 300). In this way, at least the overpressure phenomenon can be further alleviated, thereby improving functional safety.

[0040] Alternatively or additionally, when the shut-off valve 1 and / or the hydrogen injection valve 6 are closed, the hydrogen heat exchanger 2, the water separator 13, the drain valve 14, the exhaust valve 15, the first heating unit 17, and / or the second heating unit 16 may also be closed, for example, after a predetermined time. In this way, at least the power of the entire hydrogen power module anode subsystem 100 can be saved.

[0041] For example, Figure 2 As shown, the maximum pressure P-max that the inlet port 201 can withstand is much greater than the pressure threshold P-start (which can be implemented as, for example, a first pressure threshold and / or a second pressure threshold). This is to take into account the possibility that the overpressure may still increase further after closing the shut-off valve 1 and the hydrogen injection valve 6. For example, the maximum pressure P-max that the inlet port 201 can withstand can be approximately 6.25 bara. For example, the pressure threshold P-start can be approximately 2.8 bara.

[0042] like Figure 3 , a method for a hydrogen power module anode subsystem according to an exemplary embodiment of the present application is shown. The method includes the following.

[0043] Step S102: Determine whether the first pressure sensor 9 and / or the second pressure sensor 11 are working properly; if not, close the shutoff valve 1 and the hydrogen injection valve 6 and lock the entire hydrogen power module anode subsystem 100; if yes, proceed to step S103.

[0044] Specifically, the following measures can be taken to determine whether the first pressure sensor 9 and / or the second pressure sensor 11 are operating normally: for example, a sensor self-test circuit is configured so that the control unit periodically reads the sensor output to determine whether the output value is within the normal range. If it exceeds the preset threshold, it is determined that the LPS is operating abnormally; the internal chip of the sensor performs a self-test on modules such as the watchdog and NVM. If the self-test fails, it directly enters a safe state (diagnostic mode); at the same time, the internal chip of the FCCU will also perform a self-test to check whether the communication with the sensor is normal.

[0045] Step S103: determine whether the shut-off valve 1 is working properly; if not, close the shut-off valve 1 and the hydrogen injection valve 6 and lock the entire hydrogen power module anode subsystem 100; if yes, proceed to step S104.

[0046] Specifically, the following measures can be taken to determine whether the shut-off valve 1 is operating normally: for example, a pressure sensor is installed on each side of the anode shut-off valve to detect the pressure change before and after the anode shut-off valve is opened. If the pressure difference is abnormal, it is determined that the ASV is operating abnormally; the FCCU power stage performs a self-test to observe whether the drive current meets the conditions for driving the ASV to confirm whether the ASV is operating normally.

[0047] Step S104: determine whether the hydrogen injection valve 6 is working normally; if not, close the shut-off valve 1 and the hydrogen injection valve 6 and lock the entire hydrogen power module anode subsystem 100; if yes, proceed to step S105.

[0048] Specifically, the following measures can be taken to determine whether the hydrogen injection valve 6 is functioning properly: A pressure sensor or flow sensor is installed downstream of the hydrogen injector to detect the pressure or flow of the injected hydrogen and determine whether it matches the expected setting. If the difference is too large, it is determined that the HGI is not operating normally. The FCCU power stage performs a self-test to observe whether the drive current meets the conditions for driving the HGI to confirm whether the HGI is functioning properly.

[0049] Step S105: Determine whether overpressure is formed at the inlet port 201 on the anode side of the hydrogen power module reactor; if not, then S106: Do not perform any control operation; if so, then S107: Close the shut-off valve 1 and the hydrogen injection valve 6 and lock the entire hydrogen power module anode subsystem 100 and end.

[0050] For example, the housing of the hydrogen power module is often made of metal materials (such as aluminum alloy, stainless steel, etc.) to ensure sufficient mechanical strength. The hydrogen power module anode subsystem 100 is also often made of metal materials (such as carbon steel pipe, stainless steel pipe, etc.) to ensure a high degree of pressure bearing capacity. Connection methods can include threaded connection (including sealing ring), flange welding, and riveting. Flange welding and riveting are more preferably used because these two methods will have better airtightness.

[0051] The present application also discloses a hydrogen power module (hydrogen fuel cell system), which comprises at least the hydrogen power module anode subsystem described above.

[0052] The present application also discloses a vehicle, which at least includes the hydrogen power module (hydrogen fuel cell system) described above.
