Description

Technical Field

[0001] The present 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 Art

[0002] PEMFC (Proton Exchange Membrane Fuel Cell) is a fuel cell technology widely used in the automotive field. Its working principle is to introduce air into the cathode and hydrogen into the anode. The cathode air and the anode hydrogen react with the catalyst in the membrane electrode to generate electricity. However, a large amount of water is produced during the reaction, which accumulates in the cathode and anode.

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

[0004] However, the membrane of the fuel cell engine has specific chemical properties and has different requirements for humidity at different temperatures. Only by providing the appropriate humidity for the membrane of the stack can it be ensured to work in the high-efficiency zone. If the membrane is too dry or too wet, it will not only lead to a decrease in reaction efficiency, but also affect the life and reliability of the stack. The temperature requirement of the membrane is closely related to the operating temperature and power. At the same time, it is also necessary to consider that excessive humidity in the system under low temperature conditions may cause icing and other problems. In summary, in the related technology, the water separator cannot be adjusted according to different working conditions, and it is difficult to meet the humidity requirements of the stack membrane under different working conditions, thereby affecting the performance and life of the fuel cell. These problems need to be solved urgently. Summary of the invention

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

[0042] The following describes the anode control method, device and vehicle of the fuel cell engine of the embodiment of the present application with reference to the accompanying drawings. In view of the related technology mentioned in the background technology center, the water separator cannot adjust the humidity of the anode hydrogen according to different ambient temperatures and powers, and it is difficult to meet the humidity requirements of the stack membrane under different working conditions, thereby affecting the performance and life of the fuel cell. The present application provides an anode control method for a fuel cell engine, in which the actual temperature of the fuel cell engine can be collected. When the actual temperature is within the range between two certain temperature thresholds, the current power of the engine is obtained, and then the first hydrogen discharge action of discharging the anode exhaust gas is generated according to the current power of the engine and the target humidity and current humidity of the stack, so as to realize the regulation of the anode system of the fuel cell, and the hydrogen discharge action is generated by integrating multiple factors such as power and humidity, so as to improve the accuracy of adjusting the humidity of the anode hydrogen, thereby ensuring that the fuel cell operates in a suitable environment, improving the performance of the fuel cell, and extending the life of the stack. Thus, the problem that the water separator cannot adjust the humidity of the anode hydrogen according to different ambient temperatures and powers in the related technology, and it is difficult to meet the humidity requirements of the stack membrane under different working conditions, thereby affecting the performance and life of the fuel cell is solved.

[0043] Before elaborating on the method involved in the embodiment of the present application, the structure of the anode working system of the fuel cell engine in the embodiment of the present application is first described to better understand the operation basis and application scenarios of the subsequent method. Figure 1 As shown, the anode working system of the fuel cell engine includes: a hydrogen supply subsystem and an air supply subsystem, wherein the hydrogen supply subsystem includes: a pressure sensor 1, a pressure reducing valve 2, a hydrogen return assembly 3, a water separator 4, a water discharge solenoid valve 5 and a hydrogen discharge solenoid valve 6, the water discharge solenoid valve is used to discharge the moisture in the anode exhaust gas separated by the water separator, 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 the water and hydrogen in the anode exhaust gas, and the hydrogen return assembly is used to recycle and recycle the hydrogen after the water separation and filtration by the water separator.

[0044] Furthermore, the air supply subsystem includes: air filter 7, flow meter 8, air compressor 9, intercooler 10, humidifier 11, temperature sensor 12, pressure sensor 13, pressure sensor 14, electronic throttle 15 and hydrogen dilution device 16. The air filter is used to filter physical and chemical impurities in the air, the air compressor provides air with a certain pressure and flow rate for the fuel cell reaction, the intercooler is used to cool the intake air, the humidifier is used to humidify the intake air of the fuel cell, and the throttle and air compressor together provide a certain pressure for the fuel cell reaction. The hydrogen dilution device can achieve the concentration of hydrogen after the air and hydrogen are mixed and discharged to dilute the hydrogen tail exhaust to ensure safety.

[0045] The fuel cell engine anode working system of the embodiment of the present application further includes: a fuel cell stack 17, a three-way valve A18, a pipeline 19, and a pipeline 20. Figure 1 It can be seen that the system is equipped with two solenoid valves, a drain valve and a hydrogen drain valve. The hydrogen drain valve is located before the anode hydrogen outlet enters the hydrogen return assembly. If the system needs to drain hydrogen, the hydrogen drain valve opens to discharge the anode exhaust gas in the system, so as to clean the nitrogen accumulated at the anode and increase the concentration of hydrogen. A three-way valve A is added at the anode hydrogen outlet of the stack to adjust the flow of anode hydrogen into pipelines 19 and 20. If the anode hydrogen outlet enters pipeline 19, it will not pass through the water separator and directly enter the hydrogen return assembly. The humidity is high, which can increase the working humidity of the stack. If the anode hydrogen outlet enters pipeline 20, it will enter the hydrogen return assembly after water separation by the water separator. The humidity is low, which can reduce the working humidity of the stack.

[0046] The above is an introduction to the anode working system of the fuel cell engine related to the embodiment of the present application. Therefore, based on the above system, the anode control method of the fuel cell engine of the embodiment of the present application is described in detail below.

[0047] Specifically, Figure 2 A schematic flow chart of an anode control method for a fuel cell engine provided in an embodiment of the present application.

[0048] like Figure 2 As shown, the anode control method of the 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 can be understood that the temperature sensor in the above-mentioned fuel cell engine anode working system 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 mastering the actual temperature can these changes be effectively responded to and adjusted.

[0051] During the actual implementation process, the temperature sensor converts the collected temperature signals into electrical signals for transmission. The embodiments of the present application process and analyze these signals to obtain the actual temperature value. In this process, signal interference and data loss need to be avoided. 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 acquired.

[0053] It can be understood that the current power refers to the output power of the fuel cell engine at the current moment, which 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 change of the load. The current power is obtained to adjust the control strategy of the anode system according to the actual working conditions to ensure that the fuel cell can operate stably under different powers and maintain good performance and efficiency. The first preset temperature threshold and the second preset temperature threshold are obtained by experimental data and / or theoretical analysis.

[0054] In some cases, when the actual temperature is less than the first temperature threshold, the hydrogen at all anode outlets is controlled to pass into the water separator of the fuel cell engine, thereby reducing the humidity of the fuel cell engine anode working system and preventing the anode from freezing under low temperature conditions.

[0055] In step S203, a corresponding first hydrogen exhaust action for exhausting 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.

[0056] It can be understood that the target humidity of the stack refers to the ideal humidity value set in order to enable the fuel cell stack to operate at the best performance state. Humidity has an important influence on the performance of the fuel cell. Appropriate humidity can ensure the good conductivity of the proton exchange membrane, promote the smooth progress of the electrochemical reaction, and improve the efficiency and life of the battery. 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 properties, and working conditions. The first hydrogen discharge action can be understood as a specific operating instruction or action method for discharging hydrogen from the fuel cell anode exhaust gas generated under specific conditions based on information such as the current power of the engine and / or the target humidity and current humidity of the stack. Detailed examples are given below.

[0057] Optionally, in one embodiment of the present application, a first hydrogen discharge action for discharging anode exhaust gas corresponding to the current power of the engine and / or the target humidity and current humidity of the fuel cell stack is generated, including: when the current power is less than a first preset power threshold, determining the first hydrogen discharge action as prohibiting the hydrogen at all anode outlets from passing into the water separator of the fuel cell engine; when the current power is greater than a second preset power threshold, determining the first hydrogen discharge action as controlling the hydrogen at all anode outlets to pass into the water separator 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 through the water separator based on the current power, and adjusting the first target flow based on the target humidity and the current humidity to determine the first hydrogen discharge action.

[0058] In the actual implementation process, when the current power is less than the first power threshold, the three-way valve A adjusts the pipelines that do not pass through the water separator to be fully opened, and the pipelines that pass through the water separator are fully closed, and all the hydrogen at the anode outlet does not pass through the water separator, thereby increasing the humidity of the system and preventing the system from producing less water under low power conditions, causing membrane drying; when the current power is greater than the second power threshold, the three-way valve A adjusts the pipelines that pass through the water separator to be fully opened, and the pipelines that do not pass through the water separator are fully closed, and all the hydrogen at the anode outlet passes through the water separator, thereby reducing the humidity of the system and preventing the system from producing more water under high power conditions, causing flooding of the fuel cell stack.

[0059] In some cases, when the current power is between the first power threshold and the second power threshold or equal to the first power threshold or the second power threshold, the opening of the three-way valve A is first set according to the current power, and then the target humidity of the fuel cell stack and the actual humidity of the current fuel cell stack need to be obtained at the current power. When the actual humidity is lower than the target humidity, the three-way valve A increases the flow rate of the anode outlet hydrogen through the pipeline that does not pass through the water separator and reduces the hydrogen flow rate through the pipeline that passes through the water separator by adjusting the opening, thereby increasing the system humidity and re-judging the actual humidity and target humidity.

[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, and the specific meaning and value are set based on the characteristics of the fuel cell, experimental data, engineering experience and other premises), the three-way valve A increases the flow rate of the anode outlet hydrogen through the pipeline passing through the water separator and reduces the hydrogen flow rate of the pipeline not passing through the water separator by adjusting the opening, thereby reducing the humidity of the system and re-judging the actual humidity and target humidity.

[0061] In addition, in some cases, the actual humidity is greater than or equal to the target humidity or less than or equal to the target humidity plus M, and the three-way valve A maintains the current opening.

[0062] Optionally, in one embodiment of the present application, when the actual temperature is greater than the second preset temperature threshold and the current power is less than the third preset power threshold, the hydrogen at all anode outlets is prohibited from entering the water separator 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, the hydrogen at all anode outlets is controlled to enter the water separator 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 corresponding second hydrogen discharge action for discharging the 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 corresponding second hydrogen discharge action for discharging 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, including: generating a second target flow through the water separator based on the current power, and adjusting the target flow 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 power of the current engine. If the current engine power is less than the third power threshold, the three-way valve A adjusts the pipelines that do not pass through the water separator to be fully open, and the pipelines that pass through the water separator are fully closed. All the hydrogen at the anode outlet does not pass through the water separator, thereby increasing the humidity of the system and preventing the system from producing less water under low power conditions, causing membrane drying; if the current engine power is greater than the fourth power threshold, the three-way valve A adjusts the pipelines that pass through the water separator to be fully open, and the pipelines that do not pass through the water separator are fully closed. All the hydrogen at the anode outlet passes through the water separator, thereby reducing the humidity of the system and preventing the system from producing more water under high power conditions, causing 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, and then the target humidity of the fuel cell stack and the actual humidity of the current fuel cell stack under the current power need to be obtained. If the actual humidity is less than the target humidity, the three-way valve A increases the flow rate of the anode outlet hydrogen through the pipeline that does not pass through the water separator by adjusting the opening, and reduces the hydrogen flow rate of the pipeline that passes through the water separator, thereby increasing the system humidity, and re-judging the actual humidity and the target humidity; 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, and the specific meaning and value are set based on the characteristics of the fuel cell, experimental data, engineering experience and other premises), the three-way valve A increases the flow rate of the anode outlet hydrogen through the pipeline that passes through the water separator by adjusting the opening, and reduces the hydrogen flow rate of the pipeline that does not pass through the water separator, thereby reducing the system humidity, and re-judging the actual humidity and the target humidity; 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 the current opening.

[0066] Specifically, the curve of the opening of the three-way valve A changing with temperature and power is as follows: Figure 3 As shown by Figure 3It can be seen that the horizontal axis represents the power of the fuel cell engine, and the power gradually increases from left to right. Different power intervals are divided in the figure, and P1 (the first power threshold), P2 (the second power threshold), P3 (the third power threshold), and P4 (the fourth power threshold) are used to represent the key power threshold points. These power threshold points divide the entire power range into different areas, and each area corresponds to a different three-way valve A opening control strategy. For example, when operating at low power (power is less than P1 or P3), more hydrogen may be required to pass through a specific pipeline to increase the system humidity and prevent membrane drying; when operating at high power (power is greater than P2 or P4), the opening of the three-way valve A may need to be adjusted to allow more hydrogen to pass through another pipeline to reduce the system humidity and prevent the stack from being flooded.

[0067] Furthermore, the ordinate represents the opening of the three-way valve A, and the opening gradually increases from bottom to top. Fully open means that the three-way valve A is fully open, allowing the anode hydrogen to pass through the corresponding pipeline at the maximum flow rate; fully closed means that the three-way valve A is completely closed, preventing the anode hydrogen from passing through the pipeline. Different temperature intervals (T1<T0<T2 and T0>T2) have different curves, which shows that temperature will also affect the opening control strategy of the three-way valve A. For example, in the low temperature interval T1<T0<T2, the opening of the three-way valve A may be more inclined to allow hydrogen to pass through the pipeline that can increase humidity to prevent problems such as membrane drying and anode icing at low temperatures; while in the high temperature interval T0>T2, the opening control may focus more on heat dissipation and preventing flooding.

[0068] The above-mentioned 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) are fixed judgment constants and need to be set in advance by the manufacturer, where P1<P3<P2<P4.

[0069] The above method is described below with a specific embodiment, as shown in FIG4(a). The principle of the anode control method of the fuel cell engine is as follows, as shown in FIG4(b):

[0070] Step S401: Start.

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

[0072] Use the temperature sensor to collect the actual temperature of the current environment, recorded as T0.

[0073] Step S403: T0<T1.

[0074] If T0 is less than T1, and T1 is a certain threshold value obtained according to experimental data or theoretical analysis, then execute step S404; otherwise, execute S407.

[0075] Step S404: the three-way valve A adjusts the pipeline 20 to be fully open and the pipeline 19 to be fully closed.

[0076] Pipeline 20 is a pipeline passing through the water distributor, and pipeline 19 is a pipeline not passing through the water distributor.

[0077] Step S405: All the hydrogen at the anode outlet passes through the water separator.

[0078] The hydrogen at all anode outlets is controlled to flow into the water separator of the fuel cell engine, thereby reducing the humidity of the anode working system of the fuel cell engine and preventing the anode from freezing under low temperature conditions.

[0079] Step S406: End.

[0080] Subprocess 1 ends.

[0081] Step S407: T0>T2.

[0082] If T0 is greater than T2, and T2 is a certain threshold value obtained according to experimental data or theoretical analysis, then execute step S425; otherwise, execute S408.

[0083] Step S408: Obtain the current engine power P0.

[0084] Current power refers to the output power of the fuel cell engine at the current moment, which reflects the current working state and energy output level of the fuel cell.

[0085] As shown in Figure 4(b):

[0086] Step S409: P0<P1.

[0087] If P0 is less than P1, and P1 is set by the manufacturer, then execute step S410; otherwise, execute step S413;

[0088] Step S410: The three-way valve A adjusts pipeline 19 to be fully open and pipeline 20 to be fully closed.

[0089] Step S411: All hydrogen at the anode outlet does not pass through the water separator.

[0090] Increase the humidity of the system to prevent the system from producing less water under low power conditions, causing the membrane to dry out.

[0091] Step S412: End.

[0092] Subprocess 2 ends.

[0093] Step S413: P0>P2.

[0094] If P0 is greater than P2, and P2 is the factory setting, then execute step S414; otherwise, execute step S417.

[0095] Step S414: the three-way valve A adjusts the pipeline 20 to be fully open and the pipeline 19 to be fully closed.

[0096] Step S415: All the hydrogen at the anode outlet passes through the water separator.

[0097] Reduce the system humidity to prevent excessive water production under high power conditions, which may cause flooding of the fuel cell stack.

[0098] Step S416: End.

[0099] Subprocess 3 ends.

[0100] Step S417: setting the opening of the three-way valve A according to the power.

[0101] The three-way valve A has different opening states, from fully open to fully closed and various intermediate states in between, and is used to adjust the flow distribution of anode hydrogen entering different pipelines.

[0102] Step S418: Obtain the target humidity of the fuel cell stack at the current power and the actual humidity of the current fuel cell stack.

[0103] By obtaining the target humidity and the actual humidity, the embodiment of the present application can adjust the humidity of the anode hydrogen according to the difference between the two, so that the fuel cell stack always operates in an optimal humidity environment, avoiding problems such as decreased reaction efficiency due to excessively high or low humidity, and optimizing the performance of the fuel cell.

[0104] Step S419: actual humidity < target humidity.

[0105] If the actual humidity is less than the target humidity, execute step S420; otherwise, execute step S421.

[0106] Step S420: the three-way valve A increases the flow rate of hydrogen at the anode outlet through pipeline 19 and reduces the flow rate of hydrogen in pipeline 20 by adjusting the opening.

[0107] Increase the system humidity and re-judge the actual humidity and target humidity.

[0108] Step S421: actual temperature>target temperature+M.

[0109] If the actual temperature is greater than the target temperature plus M, execute step S422; otherwise, execute step S423.

[0110] Step S422: The three-way valve A increases the flow rate of hydrogen at the anode outlet through pipeline 20 and reduces the flow rate of hydrogen in pipeline 19 by adjusting the opening.

[0111] Increase the flow rate of hydrogen at the anode outlet through the pipeline passing through the water separator, reduce the flow rate of hydrogen in the pipeline not passing through the water separator, thereby reducing the humidity of the system, and re-judge the actual humidity and target humidity.

[0112] Step S423: The three-way valve A maintains the current opening.

[0113] Step S424: End.

[0114] Subprocess 4 ends.

[0115] As shown in Figure 4(c):

[0116] Step S425: Obtain the current engine power P0.

[0117] Step S426: P0<P3.

[0118] If P0 is less than P3 and P3 is the manufacturer's setting, execute step S430; otherwise, execute step S427.

[0119] Step S427: The three-way valve A adjusts pipeline 19 to be fully open and pipeline 20 to be fully closed.

[0120] Increase the humidity of the system to prevent the system from producing less water under low power conditions, causing the membrane to dry out.

[0121] Step S428: All hydrogen gas at the anode outlet does not pass through the water separator.

[0122] Step S429: End.

[0123] Subprocess 5 ends.

[0124] Step S430: P0>P4.

[0125] If P0 is greater than P4, P4 is the factory setting, then execute step S431; otherwise, execute step S434.

[0126] Step S431: The three-way valve A adjusts pipeline 20 to be fully open and pipeline 19 to be fully closed.

[0127] Step S432: All the hydrogen at the anode outlet passes through the water separator.

[0128] Reduce the system humidity to prevent excessive water production under high power conditions, which may cause flooding of the fuel cell stack.

[0129] Step S433: End.

[0130] Subprocess 6 ends.

[0131] Step S434: setting the opening of the three-way valve A according to the power.

[0132] Step S435: Obtain the target humidity of the fuel cell stack at the current power and the actual humidity of the current fuel cell stack.

[0133] For the fuel cell stack under the current power condition, an ideal humidity value determined based on multiple factors such as its design requirements, material properties, and optimal performance operating conditions is the target humidity.

[0134] Step S436: actual humidity < target humidity.

[0135] If the actual humidity is less than the target humidity, execute step S437; otherwise, execute step S438.

[0136] Step S437: The three-way valve A increases the flow rate of hydrogen at the anode outlet through pipeline 19 and reduces the flow rate of hydrogen in pipeline 20 by adjusting the opening.

[0137] Increase the flow rate of hydrogen at the anode outlet through the pipeline that does not pass through the water separator, reduce the flow rate of hydrogen through the pipeline that passes through the water separator, thereby increasing the system humidity, and re-judge the actual humidity and target humidity.

[0138] Step S438: actual humidity>target humidity+N.

[0139] If the actual humidity is greater than the target humidity+N, execute step S439; otherwise, execute step S440.

[0140] Step S439: The three-way valve A increases the flow rate of hydrogen at the anode outlet through pipeline 20 and reduces the flow rate of hydrogen in pipeline 19 by adjusting the opening.

[0141] Increase the flow rate of hydrogen at the anode outlet through the pipeline passing through the water separator, reduce the flow rate of hydrogen in the pipeline not passing through the water separator, thereby reducing the humidity of the system, and re-judge the actual humidity and target humidity.

[0142] Step S440: The three-way valve A maintains the current opening.

[0143] Step S441: End.

[0144] Subprocess 7 ends.
