Description

Technical Field

[0001] This application relates to the field of fuel cell engine control technology, and in particular to an anode control method, device and vehicle for a fuel cell engine. Background Technology

[0002] PEMFC (Proton Exchange Membrane Fuel Cell), a fuel cell technology widely used in the automotive field, works by introducing air into the cathode and hydrogen into the anode. The air at the cathode and the hydrogen at the anode undergo a power generation reaction in the membrane electrode assembly under the action of a catalyst. However, this reaction produces a large amount of water, which accumulates at both the cathode and anode.

[0003] In related technologies, a water separator is usually used to separate the moisture in the anode hydrogen gas, and then the wastewater is discharged periodically. That is, when the anode hydrogen gas containing moisture enters the water separator, the water separator will separate the moisture in the hydrogen gas according to its internal physical structure and working principle, and then discharge the separated wastewater from the system periodically at certain time intervals or when specific conditions are met.

[0004] However, the membrane of a fuel cell engine has specific chemical properties and different humidity requirements at different temperatures. Only by providing appropriate humidity to the membrane of the fuel cell stack can it be ensured to operate in the high-efficiency range. If the membrane is too dry or too wet, it will not only lead to a decrease in reaction efficiency but also affect the lifespan and reliability of the fuel cell stack. Moreover, the temperature requirements of the membrane are closely related to the operating temperature and power. Furthermore, it is necessary to consider the possibility of icing due to excessive humidity in low-temperature environments. In summary, in related technologies, the water distributor has the problem of not being able to adjust according to different operating conditions, making it difficult to meet the humidity requirements of the fuel cell stack membrane under different operating conditions, thus affecting the performance and lifespan of the fuel cell. These problems urgently need to be solved. Summary of the Invention

[0005] This application provides an anode control method, device, and vehicle for a fuel cell engine to solve the problems in related technologies, such as the inability of the water distributor to adjust the humidity of the anode hydrogen according to different ambient temperatures and power, making it difficult to meet the humidity requirements of the fuel cell stack membrane under different operating conditions, thereby affecting the performance and lifespan of the fuel cell.

[0006] The first aspect of this application provides an anode control method for a fuel cell engine, comprising the following steps: acquiring the actual temperature of the current environment in which the fuel cell engine is located; when the actual temperature is greater than or equal to a first preset temperature threshold and less than or equal to a second preset temperature threshold, acquiring the current power of the fuel cell engine; and generating a first hydrogen discharge action corresponding to the discharge of anode exhaust gas based on the current power of the engine and / or the target humidity and current humidity of the fuel cell stack.

[0007] Through the above technical solution, the embodiments of this application can obtain the current power of the engine when the actual temperature is less than a first temperature threshold by collecting the actual temperature and comparing it with a certain temperature threshold. Then, based on the current power, target humidity and current humidity, hydrogen emission can be controlled. This method of precise operation for a specific temperature range can more accurately adapt to different ambient temperatures and improve the adaptability and stability to temperature changes.

[0008] Optionally, in one embodiment of this application, it further includes: when the actual temperature is less than the first preset temperature threshold, controlling the hydrogen from all anode outlets to be introduced into the water distributor of the fuel cell engine.

[0009] Through the above technical solution, the embodiments of this application can introduce hydrogen into the water separator when the actual temperature is lower than a certain temperature, effectively removing moisture from the hydrogen, thereby preventing anode icing at low temperatures and ensuring the safe and stable operation of the fuel cell in a low-temperature environment.

[0010] Optionally, in one embodiment of this application, the first hydrogen discharge action, which generates corresponding discharge of anode exhaust gas based on the current power of the engine and / or the target humidity and current humidity of the fuel cell stack, includes: when the current power is less than a first preset power threshold, determining that the first hydrogen discharge action is to prohibit hydrogen from all anode outlets from entering the water distributor of the fuel cell engine; when the current power is greater than a second preset power threshold, determining that the first hydrogen discharge action is to control hydrogen from all anode outlets to enter the water distributor of the fuel cell engine, wherein the second preset power threshold is greater than the first preset power threshold; when the current power is greater than or equal to the first preset power threshold and less than or equal to the second preset power threshold, generating a first target flow rate through the water distributor based on the current power, and adjusting the first target flow rate based on the target humidity and the current humidity to determine the first hydrogen discharge action.

[0011] Through the above technical solution, the embodiments of this application can prevent hydrogen from the anode outlet from entering the water distributor when the current power is less than a certain value, thus preventing membrane drying caused by insufficient water production by the fuel cell stack at low power. When the current power is greater than a certain value, all hydrogen from the anode outlet is controlled to enter the water distributor, reducing the humidity of the anode during high power and reverse operation, and avoiding excessive water production that could lead to fuel cell stack flooding. When the current power is between two certain values, the flow rate through the water distributor is generated based on the current power, and the flow rate is adjusted according to the target humidity and the current humidity, thereby improving the accuracy of anode humidity control and enabling the fuel cell stack to operate in a suitable humidity environment under different power conditions.

[0012] Optionally, in one embodiment of this application, the method further includes: prohibiting all hydrogen from the anode outlets from entering the water distributor of the fuel cell engine when the actual temperature is greater than the second preset temperature threshold and the current power is less than the third preset power threshold; controlling all hydrogen from the anode outlets to enter the water distributor of the fuel cell engine when the actual temperature is greater than the second preset temperature threshold and the current power is greater than the fourth preset power threshold; and generating a second hydrogen discharge action corresponding to the discharge of anode exhaust gas based on the current power of the engine and / or the target humidity and current humidity of the fuel cell stack when the actual temperature is greater than the second preset temperature threshold and the current power is greater than or equal to the third preset power threshold and less than or equal to the fourth preset power threshold.

[0013] Through the above technical solutions, the embodiments of this application can prohibit hydrogen from entering the water distributor when the actual temperature is greater than a certain value and the current power is less than a certain value. In this case, the fuel cell stack produces less water, and prohibiting hydrogen from entering the water distributor can avoid excessive dehumidification and prevent the membrane from drying out. When the actual temperature is greater than a certain value and the current power is greater than a certain value, hydrogen can be controlled to enter the water distributor. In this case, more water is produced, so water can be discharged in time to prevent the fuel cell stack from being flooded. When the actual temperature is greater than a certain temperature and the current power is between two certain values, hydrogen is discharged according to the current power of the engine and / or the target humidity and current humidity of the fuel cell stack, thereby improving the adaptability to complex environments.

[0014] Optionally, in one embodiment of this application, the second hydrogen discharge action, which generates corresponding discharge anode exhaust gas based on the current power of the engine and / or the target humidity and current humidity of the fuel cell stack, includes: generating a second target flow rate through the water distributor based on the current power, and adjusting the target flow rate based on the second target humidity and the current humidity to determine the second hydrogen discharge action.

[0015] Through the above technical solution, the embodiments of this application can combine the relationship between power and water production rate, and determine the flow rate basis based on the different water production conditions of the fuel cell stack under different power levels. This enables the flow rate setting to better fit the actual working conditions and improve the accuracy and flexibility of humidity regulation.

[0016] A second aspect of this application provides an anode control device for a fuel cell engine, comprising: a data acquisition module for acquiring the actual temperature of the current environment in which the fuel cell engine is located; an acquisition module for acquiring the current power of the fuel cell engine when the actual temperature is greater than or equal to a first preset temperature threshold and less than or equal to a second preset temperature threshold; and a first control module for generating a first hydrogen discharge action corresponding to the discharge of anode exhaust gas based on the current power of the engine and / or the target humidity and current humidity of the fuel cell stack.

[0017] Through the above technical solution, the embodiments of this application can collect the actual temperature and compare it with a certain temperature threshold to perform precise operation for a specific temperature range, more accurately adapt to different ambient temperatures, and improve the adaptability and stability to temperature changes.

[0018] Optionally, in one embodiment of this application, it further includes: a second control module, configured to control the hydrogen from all anode outlets to be introduced into the water distributor of the fuel cell engine when the actual temperature is less than the first preset temperature threshold.

[0019] Through the above technical solution, the embodiments of this application can introduce hydrogen into the water separator when the actual temperature is lower than a certain temperature, effectively removing moisture from the hydrogen, thereby preventing anode icing at low temperatures and ensuring the safe and stable operation of the fuel cell in a low-temperature environment.

[0020] Optionally, in one embodiment of this application, the first control module includes: a first control unit, configured to determine, when the current power is less than a first preset power threshold, that the first hydrogen discharge action is to prohibit hydrogen from all anode outlets from entering the water distributor of the fuel cell engine; a second control unit, configured to determine, when the current power is greater than a second preset power threshold, that the first hydrogen discharge action is to control hydrogen from all anode outlets to enter the water distributor of the fuel cell engine, wherein the second preset power threshold is greater than the first preset power threshold; and a third control unit, configured to, when the current power is greater than or equal to the first preset power threshold and less than or equal to the second preset power threshold, generate a first target flow rate through the water distributor based on the current power, and adjust the first target flow rate based on the target humidity and the current humidity to determine the first hydrogen discharge action.

[0021] Through the above technical solution, the embodiments of this application can prevent hydrogen from the anode outlet from entering the water distributor when the current power is less than a certain value, thus preventing membrane drying caused by insufficient water production by the fuel cell stack at low power. When the current power is greater than a certain value, all hydrogen from the anode outlet is controlled to enter the water distributor, reducing the humidity of the anode during high power and reverse operation, and avoiding excessive water production that could lead to fuel cell stack flooding. When the current power is between two certain values, the flow rate through the water distributor is generated based on the current power, and the flow rate is adjusted according to the target humidity and the current humidity, thereby improving the accuracy of anode humidity control and enabling the fuel cell stack to operate in a suitable humidity environment under different power conditions.

[0022] Optionally, in one embodiment of this application, the first control module further includes: a fourth control unit, configured to prohibit all hydrogen gas from the anode outlet from entering the water distributor of the fuel cell engine when the actual temperature is greater than the second preset temperature threshold and the current power is less than the third preset power threshold; a fifth control unit, configured to control all hydrogen gas from the anode outlet to enter the water distributor of the fuel cell engine when the actual temperature is greater than the second preset temperature threshold and the current power is greater than the fourth preset power threshold; and a sixth control unit, configured to generate a second hydrogen discharge action corresponding to the discharge of anode exhaust gas based on the current power of the engine and / or the target humidity and current humidity of the fuel cell stack when the actual temperature is greater than the second preset temperature threshold and the current power is greater than or equal to the third preset power threshold and less than or equal to the fourth preset power threshold.

[0023] Through the above technical solutions, the embodiments of this application can prohibit hydrogen from entering the water distributor when the actual temperature is greater than a certain value and the current power is less than a certain value. In this case, the fuel cell stack produces less water, and prohibiting hydrogen from entering the water distributor can avoid excessive dehumidification and prevent the membrane from drying out. When the actual temperature is greater than a certain value and the current power is greater than a certain value, hydrogen can be controlled to enter the water distributor. In this case, more water is produced, so water can be discharged in time to prevent the fuel cell stack from being flooded. When the actual temperature is greater than a certain temperature and the current power is between two certain values, hydrogen is discharged according to the current power of the engine and / or the target humidity and current humidity of the fuel cell stack, thereby improving the adaptability to complex environments.

[0024] Optionally, in one embodiment of this application, the second control module includes: a seventh control unit, configured to generate a second target flow rate through the water distributor based on the current power, and adjust the target flow rate based on the second target humidity and the current humidity to determine the second hydrogen discharge action.

[0025] Through the above technical solution, the embodiments of this application can combine the relationship between power and water production rate, and determine the flow rate basis based on the different water production conditions of the fuel cell stack under different power levels. This enables the flow rate setting to better fit the actual working conditions and improve the accuracy and flexibility of humidity regulation.

[0026] A third aspect of this application provides a vehicle comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the anode control method for a fuel cell engine as described in the above embodiments.

[0027] A fourth aspect of this application provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the above-described anode control method for a fuel cell engine.

[0028] A fifth aspect of this application provides a computer program product, including a computer program that, when executed, implements the above-described anode control method for a fuel cell engine.

[0029] This application embodiment can collect the actual temperature and compare it with a certain temperature threshold, operate precisely for a specific temperature range, adapt to different ambient temperatures, improve temperature adaptability and stability. At low temperatures, hydrogen can be introduced into the water distributor to prevent anode freezing. Different measures are taken according to the power level. At low power, hydrogen is prohibited from entering the water distributor to prevent membrane drying. At high power, it is introduced to prevent flooding. When the power is moderate, the flow rate is adjusted based on power and humidity to keep the stack in a suitable humidity environment at different power levels. There are also corresponding strategies when the temperature is high and the power is different. The flow rate basis can also be determined by combining the relationship between power and water production rate, improving the accuracy and flexibility of humidity regulation and enhancing adaptability to complex environments.

[0041] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0042] The following description, with reference to the accompanying drawings, illustrates an anode control method, apparatus, and vehicle for a fuel cell engine according to embodiments of this application. Addressing the issues raised in the background section regarding the inability of the water distributor to adjust the humidity of the anode hydrogen gas according to different ambient temperatures and power levels, thus failing to meet the humidity requirements of the fuel cell stack membrane under various operating conditions and consequently affecting fuel cell performance and lifespan, this application provides an anode control method for a fuel cell engine. In this method, the actual temperature of the fuel cell engine is collected. When the actual temperature falls within a range between two certain temperature thresholds, the current engine power is obtained. Then, based on the current engine power, the target humidity of the fuel cell stack, and the current humidity, a first hydrogen discharge action is generated to expel anode exhaust gas. This achieves regulation of the fuel cell anode system, comprehensively considering power and humidity factors to generate the hydrogen discharge action, improving the accuracy of anode hydrogen gas humidity adjustment, thereby ensuring the fuel cell operates in a suitable environment, improving fuel cell performance, and extending stack lifespan. This solves the problems in the related art where the water distributor cannot adjust the humidity of the anode hydrogen gas according to different ambient temperatures and power levels, making it difficult to meet the humidity requirements of the fuel cell stack membrane under different operating conditions, thus affecting fuel cell performance and lifespan.

[0043] Before elaborating on the methods involved in the embodiments of this application, the structure of the relevant fuel cell engine anode working system in the embodiments of this application will be described first, so as to better understand the operating basis and application scenarios of the subsequent methods. Figure 1 As shown, the anode operating system of the fuel cell engine includes a hydrogen supply subsystem and an air supply subsystem. The hydrogen supply subsystem includes a pressure sensor 1, a pressure reducing valve 2, a hydrogen return assembly 3, a water separator 4, a drain solenoid valve 5, and a hydrogen discharge solenoid valve 6. The drain solenoid valve is used to discharge the moisture in the anode exhaust gas separated by the water separator, and the hydrogen discharge solenoid valve is used to discharge the waste hydrogen in the anode exhaust gas separated by the water separator. The water separator is used to separate water and hydrogen in the anode exhaust gas, and the hydrogen return assembly is used to recycle and reuse the hydrogen after it has been filtered by the water separator.

[0044] Furthermore, the air supply subsystem includes: an air filter 7, a flow meter 8, an air compressor 9, an intercooler 10, a humidifier 11, a temperature sensor 12, a pressure sensor 13, a pressure sensor 14, an electronic throttle 15, and a hydrogen dilution device 16. The air filter is used to filter physical and chemical impurities from the air. The air compressor provides air at a certain pressure and flow rate for the fuel cell reactor. The intercooler cools the intake air, and the humidifier humidifies the intake air. The throttle and air compressor together provide a certain pressure for the fuel cell reactor. The hydrogen dilution device mixes air and hydrogen before discharge to dilute the concentration of hydrogen in the exhaust, ensuring safety.

[0045] The fuel cell engine anode operating system of this embodiment further includes: a fuel cell stack 17, a three-way valve A18, a pipeline 19, and a pipeline 20. Figure 1 It is known that the system is equipped with two solenoid valves: a drain valve and a hydrogen discharge valve. The hydrogen discharge valve is located before the anode hydrogen outlet enters the hydrogen return assembly. If the system needs to discharge hydrogen, the hydrogen discharge valve opens, releasing the anode waste gas from the system, thus cleaning the nitrogen accumulated on the anode and increasing the hydrogen concentration. A three-way valve A is added at the anode hydrogen outlet of the fuel cell stack to regulate the flow rate of anode hydrogen into pipelines 19 and 20. If the anode hydrogen outlet enters pipeline 19, it bypasses the water distributor and directly enters the hydrogen return assembly, resulting in high humidity, which can increase the operating humidity of the fuel cell stack. If the anode hydrogen outlet enters pipeline 20, it passes through the water distributor before entering the hydrogen return assembly, resulting in low humidity, which can reduce the operating humidity of the fuel cell stack.

[0046] The above is an introduction to the anode operating system of the fuel cell engine related to the embodiments of this application. Therefore, based on the above system, the anode control method of the fuel cell engine of the embodiments of this application will be described in detail below.

[0047] Specifically, Figure 2 This is a schematic flowchart of an anode control method for a fuel cell engine provided in an embodiment of this application.

[0048] like Figure 2 As shown, the anode control method of this fuel cell engine includes the following steps:

[0049] In step S201, the actual temperature of the current environment of the fuel cell engine is collected.

[0050] It is understandable that the temperature sensor in the anode working system of the fuel cell engine collects the actual temperature of the current environment. The performance and stability of the fuel cell engine are significantly affected by the ambient temperature. At different temperatures, the chemical reaction rate, water evaporation and condensation inside the fuel cell will change. Only by knowing the actual temperature can these changes be effectively responded to and regulated.

[0051] In actual operation, the temperature sensor converts the collected temperature signal into an electrical signal for transmission. In this embodiment, these signals are processed and analyzed to obtain the actual temperature value. In this process, it is necessary to avoid signal interference and data loss. The collected temperature data needs to be properly processed and calibrated to improve the accuracy and reliability of the data.

[0052] In step S202, when the actual temperature is greater than or equal to the first preset temperature threshold and less than or equal to the second preset temperature threshold, the current power of the fuel cell engine is obtained.

[0053] It is understandable that the current power refers to the output power of the fuel cell engine at the current moment. It reflects the current working state and energy output level of the fuel cell. During the operation of the fuel cell, the power will change with the load. Obtaining the current power is to adjust the control strategy of the anode system according to the actual working conditions, so as to ensure that the fuel cell can operate stably under different power and maintain good performance and efficiency. The first preset temperature threshold and the second preset temperature threshold are obtained from experimental data and / or theoretical analysis.

[0054] In some cases, when the actual temperature is below the first temperature threshold, hydrogen from all anode outlets is controlled to flow into the water distributor of the fuel cell engine, thereby reducing the humidity of the fuel cell engine anode operating system and preventing anode icing under low temperature conditions.

[0055] In step S203, a first hydrogen discharge action corresponding to the discharge of anode exhaust gas is generated based on the engine's current power and / or the target humidity and current humidity of the fuel cell stack.

[0056] It is understandable that the target humidity of the fuel cell stack refers to the ideal humidity value set to ensure that the fuel cell stack operates at its best performance. Humidity has a significant impact on fuel cell performance; suitable humidity ensures good conductivity of the proton exchange membrane, promotes smooth electrochemical reactions, and improves battery efficiency and lifespan. The target humidity is an optimal humidity range or specific value determined through experimental and theoretical analysis based on factors such as the type of fuel cell, material characteristics, and operating conditions. The first hydrogen venting action can be understood as a specific operational command or action generated under specific conditions based on information such as the engine's current power and / or the target humidity and current humidity of the fuel cell stack, used to vent hydrogen from the fuel cell anode exhaust gas. Detailed examples are provided below.

[0057] Optionally, in one embodiment of this application, generating a first hydrogen discharge action corresponding to the discharge of anode exhaust gas based on the current power of the engine and / or the target humidity and current humidity of the fuel cell stack includes: when the current power is less than a first preset power threshold, determining the first hydrogen discharge action to prohibit hydrogen from all anode outlets from entering the water distributor of the fuel cell engine; when the current power is greater than a second preset power threshold, determining the first hydrogen discharge action to control hydrogen from all anode outlets from entering the water distributor of the fuel cell engine, wherein the second preset power threshold is greater than the first preset power threshold; when the current power is greater than or equal to the first preset power threshold and less than or equal to the second preset power threshold, generating a first target flow rate through the water distributor based on the current power, and adjusting the first target flow rate based on the target humidity and current humidity to determine the first hydrogen discharge action.

[0058] In actual operation, when the current power is less than the first power threshold, the three-way valve A adjusts the pipeline that does not pass through the water distributor to be fully open, and the pipeline that does pass through the water distributor to be fully closed. All hydrogen gas at the anode outlet does not pass through the water distributor, thereby increasing the system humidity and preventing the system from producing too little water and causing the membrane to dry out under low power conditions. When the current power is greater than the second power threshold, the three-way valve A adjusts the pipeline that passes through the water distributor to be fully open, and the pipeline that does not pass through the water distributor to be fully closed. All hydrogen gas at the anode outlet passes through the water distributor, thereby decreasing the system humidity and preventing the fuel cell stack from being flooded due to excessive water production under high power conditions.

[0059] In some cases, when the current power is between or equal to the first or second power threshold, the opening of the three-way valve A is first set according to the current power. Then, the target humidity and the actual humidity of the fuel cell stack at the current power need to be obtained. When the actual humidity is less than the target humidity, the three-way valve A increases the flow rate of hydrogen gas through the pipeline without passing through the water distributor by adjusting the opening, and reduces the flow rate of hydrogen gas through the pipeline with the water distributor, thereby increasing the system humidity. The actual humidity and the target humidity are then reassessed.

[0060] In other cases, when the actual humidity is greater than the target humidity plus M (M is a specific judgment constant used to define the deviation range between the actual humidity and the target humidity in the control logic; its specific meaning and value are set based on the characteristics of the fuel cell, experimental data, and engineering experience), the three-way valve A adjusts its opening to increase the flow rate of hydrogen gas from the anode outlet through the pipe passing through the water distributor and reduce the flow rate of hydrogen gas in the pipe not passing through the water distributor, thereby reducing the humidity of the system and re-judging the actual humidity and the target humidity.

[0061] In addition, in some cases, if the actual humidity is greater than or equal to the target humidity or less than or equal to the target humidity plus M, then the three-way valve A will remain at its current opening.

[0062] Optionally, in one embodiment of this application, when the actual temperature is greater than a second preset temperature threshold and the current power is less than a third preset power threshold, all hydrogen gas from the anode outlet is prohibited from entering the water distributor of the fuel cell engine; when the actual temperature is greater than the second preset temperature threshold and the current power is greater than a fourth preset power threshold, all hydrogen gas from the anode outlet is controlled to enter the water distributor of the fuel cell engine; when the actual temperature is greater than the second preset temperature threshold and the current power is greater than or equal to the third preset power threshold and less than or equal to the fourth preset power threshold, a second hydrogen discharge action corresponding to the discharge of anode exhaust gas is generated according to the current power of the engine and / or the target humidity and current humidity of the fuel cell stack.

[0063] Specifically, a second hydrogen discharge action is generated based on the engine's current power and / or the target humidity and current humidity of the fuel cell stack, including: generating a second target flow rate through the water distributor based on the current power, and adjusting the target flow rate based on the second target humidity and the current humidity to determine the second hydrogen discharge action.

[0064] In some embodiments, when the actual temperature is greater than the second temperature threshold, it is necessary to obtain the current engine power. If the current engine power is less than the third power threshold, the three-way valve A adjusts the pipeline that does not pass through the water distributor to be fully open, and the pipeline that does pass through the water distributor to be fully closed. All hydrogen gas at the anode outlet does not pass through the water distributor, thereby increasing the system humidity and preventing the system from producing less water under low power conditions, which could cause membrane drying. If the current engine power is greater than the fourth power threshold, the three-way valve A adjusts the pipeline that passes through the water distributor to be fully open, and the pipeline that does not pass through the water distributor to be fully closed. All hydrogen gas at the anode outlet passes through the water distributor, thereby decreasing the system humidity and preventing the production of more water under high power conditions, which could cause flooding of the fuel cell stack.

[0065] In other embodiments, if the current engine power is greater than or equal to the third power threshold and less than or equal to the fourth power threshold, the opening of the three-way valve A is first set according to the power. Then, the target humidity and the actual humidity of the fuel cell stack at the current power are obtained. If the actual humidity is less than the target humidity, the three-way valve A adjusts its opening to increase the flow rate of hydrogen from the anode outlet through the pipe without the water separator and decrease the flow rate through the pipe with the water separator, thereby increasing the system humidity. The actual humidity and target humidity are then reassessed. If the actual humidity is greater than the target temperature plus N (a specific judgment constant used to define the deviation range between the actual humidity and the target humidity in the control logic; its specific meaning and value are set based on the characteristics of the fuel cell, experimental data, and engineering experience), the three-way valve A adjusts its opening to increase the flow rate of hydrogen from the anode outlet through the pipe with the water separator and decrease the flow rate through the pipe without the water separator, thereby reducing the system humidity. The actual humidity and target humidity are then reassessed. If the actual humidity is greater than or equal to the target humidity and less than or equal to the target humidity plus N, the three-way valve A maintains its current opening.

[0066] Specifically, the curves showing the change in the opening degree of the three-way valve A with temperature and power are as follows: Figure 3 As shown, by Figure 3As can be seen, the horizontal axis represents the power of the fuel cell engine, which gradually increases from left to right. The figure divides different power ranges, with P1 (first power threshold), P2 (second power threshold), P3 (third power threshold), and P4 (fourth power threshold) representing key power threshold points. These power threshold points divide the entire power range into different regions, each corresponding to a different three-way valve A opening control strategy. For example, when operating at low power (power less than P1 or P3), more hydrogen may need to pass through a specific pipeline to increase system humidity and prevent membrane drying; while when operating at high power (power greater than P2 or P4), it may be necessary to adjust the opening of the three-way valve A to allow more hydrogen to pass through another pipeline to reduce system humidity and prevent the fuel cell stack from being flooded.

[0067] Furthermore, the vertical axis represents the opening degree of three-way valve A, gradually increasing from bottom to top. Fully open means three-way valve A is completely open, allowing anode hydrogen to flow through the corresponding pipeline at maximum flow rate; fully closed means three-way valve A is completely closed, preventing anode hydrogen from flowing through the pipeline. Different temperature ranges (T1 < T0 < T2 and T0 > T2) show different curves, indicating that temperature also affects the opening degree control strategy of three-way valve A. For example, in the lower temperature range of T1 < T0 < T2, the opening degree of three-way valve A may be more inclined to allow hydrogen to flow through pipelines that increase humidity to prevent problems such as film drying and anode icing at low temperatures; while in the higher temperature range of T0 > T2, the opening degree control may focus more on heat dissipation and preventing flooding.

[0068] The T1 (first temperature threshold), T2 (second temperature threshold), P1 (first power threshold), P2 (second power threshold), P3 (third power threshold), and P4 (fourth power threshold) mentioned above are fixed judgment constants that need to be set in advance by the manufacturer. Among them, P1 < P3 < P2 < P4.

[0069] The above method is illustrated below with a specific embodiment, as shown in Figure 4(a). The principle of the anode control method of this fuel cell engine is as follows, as shown in Figure 4(b):

[0070] Step S401: Begin.

[0071] Step S402: Obtain the current ambient temperature T0.

[0072] The actual temperature of the current environment is collected using a temperature sensor and denoted as T0.

[0073] Step S403: T0 < T1.

[0074] If T0 is less than T1, where T1 is a certain threshold obtained from experimental data or theoretical analysis, then proceed to step S404; otherwise, proceed to step S407.

[0145] In summary, the entire process achieves precise adjustment of the fuel cell engine anode system through comprehensive judgment and control of ambient temperature, engine power, and stack humidity. This ensures that the fuel cell can operate in a suitable humidity environment under different operating conditions, thereby improving performance and stability and extending service life.

[0146] According to the anode control method for a fuel cell engine proposed in this application, the actual temperature of the fuel cell engine can be collected. When the actual temperature is within the range of two certain temperature thresholds, the current power of the engine is obtained. Then, based on the current power of the engine, the target humidity of the fuel cell stack, and the current humidity, the first hydrogen discharge action to discharge the anode exhaust gas is generated to achieve the regulation of the fuel cell anode system. The hydrogen discharge action is generated by combining multiple factors such as power and humidity, which improves the accuracy of regulating the humidity of the anode hydrogen gas, thereby ensuring that the fuel cell operates in a suitable environment, improving the performance of the fuel cell, and extending the life of the fuel cell stack.

[0150] Specifically, the data acquisition module 100 is used to acquire the actual temperature of the current environment in which the fuel cell engine is located.

[0151] The acquisition module 200 is used to acquire the current power of the fuel cell engine when the actual temperature is greater than or equal to a first preset temperature threshold and less than or equal to a second preset temperature threshold.

[0152] The first control module 300 is used to generate a first hydrogen discharge action corresponding to the discharge of anode exhaust gas based on the engine's current power and / or the target humidity and current humidity of the fuel cell stack.

[0153] Optionally, in one embodiment of this application, it further includes: a second control module 400, used to control the hydrogen from all anode outlets to be introduced into the water distributor of the fuel cell engine when the actual temperature is less than a first preset temperature threshold.

[0154] Optionally, in one embodiment of this application, the first control module 300 includes: a first control unit, a second control unit, and a third control unit.

[0155] The first control unit is used to determine, when the current power is less than a first preset power threshold, that the first hydrogen discharge action is to prohibit all hydrogen from the anode outlets from entering the water distributor of the fuel cell engine.

[0156] The second control unit determines that the first hydrogen discharge action is to control the hydrogen from all anode outlets to be introduced into the water distributor of the fuel cell engine when the current power is greater than the second preset power threshold.

[0157] The third control unit is used to generate a first target flow rate through the water distributor based on the current power when the current power is greater than or equal to a first preset power threshold and less than or equal to a second preset power threshold, and to adjust the first target flow rate based on the target humidity and the current humidity to determine the first hydrogen discharge action.

[0158] Optionally, in one embodiment of this application, the first control module 300 further includes a fourth control unit, a fifth control unit, and a sixth control unit.

[0159] The fourth control unit is used to prevent hydrogen from all anode outlets from entering the water distributor of the fuel cell engine when the actual temperature is greater than the second preset temperature threshold and the current power is less than the third preset power threshold.

[0160] The fifth control unit is used to control the hydrogen from all anode outlets to be introduced into the water distributor of the fuel cell engine when the actual temperature is greater than the second preset temperature threshold and the current power is greater than the fourth preset power threshold.

[0161] The sixth control unit is used to generate a second hydrogen discharge action corresponding to the discharge of anode exhaust gas when the actual temperature is greater than the second preset temperature threshold and the current power is greater than or equal to the third preset power threshold and less than or equal to the fourth preset power threshold, based on the current power of the engine and / or the target humidity and current humidity of the fuel cell stack.

[0162] Optionally, in one embodiment of this application, the second control module 400 includes: a seventh control unit, configured to generate a second target flow rate through the water distributor based on the current power, and adjust the target flow rate based on the second target humidity and the current humidity to determine the second hydrogen discharge action.

[0163] It should be noted that the foregoing explanation of the embodiment of the anode control method for a fuel cell engine also applies to the anode control device of the fuel cell engine in this embodiment, and will not be repeated here.

[0164] According to the anode control device of the fuel cell engine proposed in the embodiments of this application, the actual temperature of the fuel cell engine can be collected. When the actual temperature is within the range of two certain temperature thresholds, the current power of the engine is obtained. Then, based on the current power of the engine, the target humidity of the fuel cell stack, and the current humidity, the first hydrogen discharge action is generated to discharge the anode exhaust gas, so as to realize the regulation of the fuel cell anode system. The hydrogen discharge action is generated by combining multiple factors such as power and humidity, improving the accuracy of regulating the humidity of the anode hydrogen gas, thereby ensuring that the fuel cell operates in a suitable environment, improving the performance of the fuel cell, and extending the life of the fuel cell stack.
