Description

Technical Field

[0001] This application relates to the field of fuel cell technology, and in particular to an adaptive altitude operation method, apparatus, computer equipment, and readable storage medium for an aviation fuel cell. Background Technology

[0002] With the development of hydrogen fuel cells in various power applications, aviation fuel cell application technology has also become a research focus. Due to the special application environments of aviation and the low density and flammability of hydrogen, the safety and performance stability of aviation fuel cell systems are receiving greater attention compared to vehicle-mounted applications.

[0003] The performance of a fuel cell system is strongly correlated with its operating environment. At high altitudes, the ambient pressure, oxygen concentration, and temperature are lower than at ground level. Fuel cell stacks and their components face more stringent operating conditions and exhibit different operating characteristics. Ground-based operating conditions are difficult to meet the altitude-dependent operating conditions at high altitudes.

[0004] However, the operating parameters of fuel cell systems in related technologies are fixed. Especially when operating at high altitudes, fixed operating parameters may not be able to meet the operating requirements, resulting in lower safety of the fuel cell system. Summary of the Invention

[0005] Therefore, it is necessary to provide an adaptive altitude operation method, apparatus, computer equipment, readable storage medium, and program product for aviation fuel cells that can improve the safety of fuel cell systems under high-altitude operating conditions, in order to address the aforementioned technical problems.

[0006] In a first aspect, this application provides an adaptive altitude operation method for aviation fuel cells, including:

[0007] Obtain the operating parameters of the fuel cell system at the target altitude;

[0008] If the operating parameters do not meet the preset increase conditions, the target operating parameters of the fuel cell system are adjusted based on the preset adjustment strategy to obtain the health status parameters of the fuel cell system after adjustment.

[0009] The operating mode of the fuel cell system is determined based on the health status parameters.

[0010] In one embodiment, the fuel cell system includes at least an air compressor and a back pressure valve. The target operating parameters include at least the air compressor speed and the back pressure valve opening. If the operating parameters do not meet a preset increase condition, the target operating parameters of the fuel cell system are adjusted based on a preset adjustment strategy to obtain the adjusted fuel cell health status parameters of the fuel cell system, including:

[0011] If the air compressor speed is greater than the preset speed threshold, it is determined that the operating parameters do not meet the preset rise conditions and the preset adjustment strategy corresponding to the target altitude is determined. Based on the preset adjustment strategy, the air compressor speed and the back pressure valve opening are adjusted to obtain the adjusted air compressor speed and the adjusted back pressure valve opening.

[0012] Under the operating conditions of adjusted air compressor speed and adjusted back pressure valve opening, the health status parameters of the fuel cell in the fuel cell system are determined.

[0013] In one embodiment, the method further includes:

[0014] The hydrogen-air pressure difference is determined based on the difference between the hydrogen inlet pressure and the air inlet pressure of the fuel cell stack in the fuel cell system.

[0015] If the hydrogen-air pressure difference exceeds a preset pressure difference threshold, the target operating parameters will not be adjusted.

[0016] In one embodiment, the fuel cell system further includes a proportional valve, the hydrogen inlet pressure is determined by a hydrogen pressure sensor, the air inlet pressure is determined by an air pressure sensor, and the method further includes:

[0017] If the hydrogen infeed pressure value and / or the air infeed pressure value are not within the preset pressure range, and the fuel cell system does not meet the preset fault conditions, then it is determined that the hydrogen pressure sensor and / or the air pressure sensor are faulty.

[0018] If it is determined that the hydrogen pressure sensor and / or the air pressure sensor is faulty, then in the first correspondence between opening and altitude, the first target opening of the proportional valve and the second target opening of the back pressure valve are determined based on the target altitude. In the second correspondence between speed and altitude, the target speed of the air compressor is determined based on the target altitude. The opening of the proportional valve is adjusted to the first target opening, the opening of the back pressure valve is adjusted to the second target opening, and the speed of the air compressor is adjusted to the target speed. The health status parameters of the fuel cell system are also determined.

[0019] If the health status parameter exceeds a preset threshold range, the opening frequency of the exhaust and drain valve of the fuel cell system is changed within a first preset time range. When the voltage value of each cell in the fuel cell system is within a preset voltage range, the fuel cell system is restored to its initial state. Alternatively, when the voltage value of each cell is not within the preset voltage range, the output power of the fuel cell system is adjusted to a preset output power and the target altitude is adjusted to a preset altitude.

[0020] In one embodiment, determining that the hydrogen pressure sensor and / or the air pressure sensor is faulty if the hydrogen infeed pressure and / or the air infeed pressure are not within a preset range and the fuel cell system does not meet a preset fault condition includes:

[0021] If the hydrogen infeed pressure and / or the air infeed pressure are not within the preset range, the components of the fuel cell system are troubleshooted based on the preset fault strategy to obtain the troubleshooting results.

[0022] If the troubleshooting results indicate that none of the components of the fuel cell system are faulty, and the first operating parameter corresponding to the target altitude is within the preset parameter threshold range, then it is determined that the fuel cell system does not meet the preset fault conditions, and that the hydrogen pressure sensor and / or the air pressure sensor are faulty.

[0023] In one embodiment, the method further includes:

[0024] The single-cell voltage variance of the fuel cell system is determined based on the number of individual cells in the fuel cell system, the voltage value of each individual cell, and the average voltage value of the individual cells.

[0025] The difference between the average voltage value and the lowest voltage value of the single cell is determined as the lower deviation value of the fuel cell system.

[0026] In one embodiment, determining the operating mode of the fuel cell system based on the health status parameters includes:

[0027] If the health status parameters do not meet the preset health conditions, the opening frequency of the exhaust and drain valves of the fuel cell system is increased within a second preset time range, and the voltage value of each individual cell in the fuel cell system is determined. If the voltage value of each individual cell is within a preset voltage range, the operating mode of the fuel cell system is determined to be the rising mode; if the voltage value of each individual cell is not within the preset voltage range, the operating mode of the fuel cell system is determined to be the cruise mode; or...

[0028] If the health status parameters meet the preset health conditions, then the operating mode of the fuel cell system is determined to be the rising mode.

[0029] Secondly, this application also provides an adaptive altitude operation device for an aviation fuel cell, comprising:

[0030] The acquisition module is used to acquire the operating parameters of the fuel cell system at the target altitude.

[0031] An adjustment module is used to adjust the target operating parameters of the fuel cell system based on a preset adjustment strategy if the operating parameters do not meet the preset increase conditions, so as to obtain the adjusted health status parameters of the fuel cell system.

[0032] The determination module is used to determine the operating mode of the fuel cell system based on the health status parameters.

[0033] Thirdly, this application also provides a computer device, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to perform the following steps:

[0034] Obtain the operating parameters of the fuel cell system at the target altitude;

[0035] If the operating parameters do not meet the preset increase conditions, the target operating parameters of the fuel cell system are adjusted based on the preset adjustment strategy to obtain the health status parameters of the fuel cell system after adjustment.

[0036] The operating mode of the fuel cell system is determined based on the health status parameters.

[0037] Fourthly, this application also provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, performs the following steps:

[0038] Obtain the operating parameters of the fuel cell system at the target altitude;

[0039] If the operating parameters do not meet the preset increase conditions, the target operating parameters of the fuel cell system are adjusted based on the preset adjustment strategy to obtain the health status parameters of the fuel cell system after adjustment.

[0040] The operating mode of the fuel cell system is determined based on the health status parameters.

[0041] Fifthly, this application also provides a computer program product, including a computer program that, when executed by a processor, performs the following steps:

[0042] Obtain the operating parameters of the fuel cell system at the target altitude;

[0043] If the operating parameters do not meet the preset increase conditions, the target operating parameters of the fuel cell system are adjusted based on the preset adjustment strategy to obtain the health status parameters of the fuel cell system after adjustment.

[0044] The operating mode of the fuel cell system is determined based on the health status parameters.

[0045] The aforementioned adaptive altitude operation method, apparatus, computer equipment, readable storage medium, and program product for aviation fuel cells, during operation, acquires operating parameters corresponding to the target altitude. If the operating parameters do not meet the preset elevation conditions, the target operating parameters in the fuel cell are adjusted based on a preset adjustment strategy to obtain the adjusted health status parameters of the fuel cell system. Based on the health status parameters, the operating mode of the fuel cell system is determined. During the altitude increase process, the fuel cell system can adaptively adjust the target operating parameters according to the operating parameters of the fuel cell system, improving the environmental adaptability of the fuel cell. Furthermore, by determining the operating mode of the fuel cell system based on the health status parameters, the fuel cell system can achieve adaptive adjustment under different operating altitudes, realize stable power output, and improve the safety of the fuel cell system during operation.

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0055] In one exemplary embodiment, such as Figure 1 As shown, an adaptive altitude operation method for aviation fuel cells is provided. This embodiment illustrates the method applied to a terminal. It is understood that this method can also be applied to a server, and further to a system including both a terminal and a server, and implemented through interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0056] Step 101: Obtain the operating parameters of the fuel cell system at the target altitude.

[0057] The fuel cell system is an aviation fuel cell. The target altitude can be the current operating altitude of the fuel cell system, and the operating parameters can be the operating indicators of each component in the fuel cell system.

[0058] Specifically, the terminal can obtain the operating parameters of each component at the target altitude based on the sensor devices in the fuel cell.

[0059] Step 102: If the operating parameters do not meet the preset increase conditions, the target operating parameters of the fuel cell system are adjusted based on the preset adjustment strategy to obtain the health status parameters of the fuel cell system after adjustment.

[0060] The preset elevation conditions are used to determine whether the current system altitude can be increased. The preset adjustment strategies can include parameter adjustment strategies for various components in the fuel cell system corresponding to different operating altitudes, and the target operating parameters can be the operating parameters that need to be adjusted according to the preset adjustment strategies. Health status parameters can be used to determine whether the health status of the fuel cell system meets the altitude increase conditions.

[0061] Specifically, the terminal can determine the relationship between the current operating parameters and a preset threshold range. If the operating parameters are within the preset threshold range, it determines that the fuel cell system meets the preset ascent conditions and the altitude of the fuel cell system, and can continue to ascend based on the preset ascent strategy. If the operating parameters are not within the preset threshold range, the target operating parameters of the fuel cell system are adjusted based on a preset adjustment strategy to obtain the adjusted target operating parameters. The fuel cell system operates based on the adjusted target operating parameters. In this way, the terminal can obtain the voltage parameters of the fuel cells in the fuel cell system at the current moment and determine the adjusted health status parameters of the fuel cells based on the voltage parameters.

[0062] In addition, the terminal can determine the corresponding preset adjustment strategy based on the air flow and power requirements of the fuel cell system under different operating altitudes.

[0063] Step 103: Determine the operating mode of the fuel cell system based on health status parameters.

[0064] The operating mode can characterize the operating status of the fuel cell system. For example, the operating mode can include an elevation mode or a cruise mode. The elevation mode indicates that the operating altitude of the system is increased, while the cruise mode indicates that the operating altitude of the system is maintained or decreased.

[0065] Specifically, the terminal can determine the relationship between the health status parameters and the preset health conditions. If the health status parameters meet the preset health conditions, it indicates that the current fuel cell system can continue to rise based on the preset rise strategy; if the health status parameters do not meet the preset health conditions, it indicates that the current fuel cell system switches to cruise mode.

[0066] The aforementioned adaptive altitude operation method for aviation fuel cells acquires operating parameters corresponding to the target altitude during operation. If the operating parameters do not meet the preset altitude increase conditions, the target operating parameters in the fuel cell are adjusted based on a preset adjustment strategy to obtain the health status parameters of the fuel cell system after adjustment. Based on the health status parameters, the operating mode of the fuel cell system is determined. During the altitude increase process, the fuel cell system can adaptively adjust the target operating parameters according to the operating parameters of the fuel cell system, thereby improving the environmental adaptability of the fuel cell. Furthermore, by determining the operating mode of the fuel cell system based on the health status parameters, the fuel cell system can achieve adaptive adjustment under different operating altitudes, realize stable power output, and improve the safety of the fuel cell system during operation.

[0067] In an exemplary embodiment, the specific implementation process of step 102, "If the operating parameters do not meet the preset increase conditions, then adjust the target operating parameters of the fuel cell system based on the preset adjustment strategy to obtain the adjusted fuel cell health status parameters of the fuel cell system," may include:

[0068] If the air compressor speed is greater than the preset speed threshold, it is determined that the operating parameters do not meet the preset elevation conditions and the preset adjustment strategy corresponding to the target altitude is determined. Based on the preset adjustment strategy, the air compressor speed and back pressure valve opening are adjusted to obtain the adjusted air compressor speed and the adjusted back pressure valve opening. Under the operating conditions of the adjusted air compressor speed and the adjusted back pressure valve opening, the health status parameters of the fuel cell in the fuel cell system are determined.

[0069] The preset speed threshold can be determined based on the relationship between altitude and speed, or it can be a fixed value. The fuel cell system includes at least an air compressor and a back pressure valve, and the target operating parameters include at least the air compressor speed and the back pressure valve opening.

[0070] Specifically, the terminal can determine or acquire a preset speed threshold corresponding to the target altitude. The terminal can compare the air compressor speed with the preset speed threshold to obtain a comparison result. If the comparison result shows that the air compressor speed is greater than the preset speed threshold, it is determined that the operating parameters do not meet the preset elevation conditions. The terminal can determine a preset adjustment strategy corresponding to the target altitude, and based on the preset adjustment strategy, determine the target speed value for the air compressor at the target altitude and the target opening value for the back pressure valve. It then adjusts the air compressor speed to the target speed value to obtain the adjusted air compressor speed, and adjusts the back pressure valve opening to the target opening value to obtain the adjusted back pressure valve opening. The fuel cell system operates based on the adjusted operating parameters. The terminal can acquire the voltage parameters of the fuel cell in the fuel cell system and determine the adjusted health status parameters of the fuel cell in the fuel cell system based on the voltage parameters.

[0071] For example, when the air compressor speed is greater than a preset speed threshold, the terminal can determine the target opening degree of the back pressure valve and the target speed value of the air compressor based on a preset adjustment strategy. The terminal can increase the opening degree of the back pressure valve based on the target opening degree and decrease the speed of the air compressor based on the target speed value of the air compressor, so as to reduce the air pressure of the fuel cell system and increase the hydrogen-air pressure difference, thereby obtaining the adjusted fuel cell system.

[0072] In addition, if the air compressor speed is less than the preset speed threshold, the terminal will not adjust the fuel cell system and will continue to increase the operating altitude.

[0073] In this embodiment, by adjusting the target operating parameters based on a preset adjustment strategy when the air compressor speed is greater than a preset speed threshold, the adaptive adjustment of the fuel cell system during operation is achieved, thereby improving the environmental adaptability and safety of the fuel cell system.

[0074] In one exemplary embodiment, the adaptive altitude operation method for aviation fuel cells further includes:

[0075] The hydrogen-air pressure difference is determined based on the difference between the hydrogen inlet pressure and the air inlet pressure of the fuel cell stack in the fuel cell system; if the hydrogen-air pressure difference exceeds the preset pressure difference threshold, the target operating parameters will not be adjusted.

[0076] The hydrogen inlet pressure refers to the pipeline pressure before hydrogen enters the fuel cell stack. The air inlet pressure refers to the pipeline pressure before air enters the fuel cell stack. The preset differential pressure threshold of the fuel cell stack can be determined based on the stack's performance. The hydrogen-air differential pressure is used to prevent hydrogen leakage to the air side while ensuring uniform distribution of the reactant gases.

[0077] Specifically, during the adjustment of the fuel cell system's operating parameters, the terminal can acquire the hydrogen inlet pressure and air inlet pressure of the fuel cell stack, calculate the difference between them, and determine this difference as the hydrogen-air pressure differential. The terminal can pre-determine a preset pressure differential threshold for the fuel cell stack. When the terminal detects that the hydrogen-air pressure differential exceeds the preset threshold, it will no longer adjust the air compressor speed and back pressure valve opening.

[0078] In this embodiment, the hydrogen-air pressure difference is determined by calculating the difference between the hydrogen inlet pressure and the air inlet pressure, ensuring that the hydrogen-air pressure difference does not exceed the preset pressure difference threshold during the adjustment of the target operating parameters, thus guaranteeing the normal operation of the fuel cell stack.

[0079] In one exemplary embodiment, such as Figure 2 As shown, the adaptive altitude operation method for aviation fuel cells also includes the following steps:

[0080] Step 201: If the hydrogen infeed pressure and / or air infeed pressure are not within the preset pressure range, and the fuel cell system does not meet the preset fault conditions, then it is determined that the hydrogen pressure sensor and / or air pressure sensor are faulty.

[0081] The hydrogen inlet pressure is determined by a hydrogen pressure sensor, while the air inlet pressure is determined by an air pressure sensor. The preset pressure range can be determined based on the performance of the fuel cell stack.

[0082] Specifically, if the hydrogen inlet pressure is not within the preset pressure range, it may be due to a malfunction in the relevant components of the hydrogen pipeline or a malfunction in the operating parameters of the relevant components. Similarly, if the air inlet pressure is not within the preset pressure range, it may be due to a malfunction in the relevant components of the air pipeline or a malfunction in the operating parameters of the relevant components. Or, if both the hydrogen inlet pressure and the air inlet pressure are not within the preset pressure range, it may be due to a malfunction in the relevant components of the hydrogen pipeline and the air pipeline or a malfunction in the operating parameters of the relevant components.

[0083] The terminal can determine whether the fault lies in the relevant components and operating parameters of the hydrogen pipeline and / or air pipeline based on preset fault conditions. If the hydrogen inlet pressure is not within the preset pressure range, and the relevant components and operating parameters of the hydrogen pipeline are not faulty, then the hydrogen pressure sensor is determined to be faulty. If the air inlet pressure difference is not within the preset pressure range, and the relevant components and operating parameters of the air pipeline are not faulty, then the air sensor is determined to be faulty. If both the hydrogen inlet pressure and the air inlet pressure difference are not within the preset pressure range, and the relevant components and operating parameters of the hydrogen and oxygen pipelines are not faulty, then both the hydrogen pressure sensor and the air pressure sensor are determined to be faulty.

[0084] Step 202: If it is determined that the hydrogen pressure sensor and / or air pressure sensor are faulty, then in the first correspondence between opening and altitude, determine the first target opening of the proportional valve and the second target opening of the back pressure valve based on the target altitude. In the second correspondence between speed and altitude, determine the target speed of the air compressor based on the target altitude. Adjust the opening of the proportional valve to the first target opening, adjust the opening of the back pressure valve to the second target opening, adjust the speed of the air compressor to the target speed, and determine the health status parameters of the fuel cell system.

[0085] The fuel cell system also includes a proportional valve. The first and second correspondences can be set based on the performance of the fuel cell system.

[0086] Specifically, if a fault is determined in the hydrogen pressure sensor and / or air pressure sensor, then in the correspondence between opening degree and altitude, a first target opening degree for the proportional valve and a second target opening degree for the back pressure valve corresponding to the target altitude are determined. In the correspondence between speed and altitude, a target speed for the air compressor is determined based on the target altitude. The opening degree of the proportional valve is then adjusted to the first target opening degree, the opening degree of the back pressure valve is adjusted to the second target opening degree, and the air compressor speed is adjusted to the target speed. The fuel cell system operates based on the adjusted operating parameters. The terminal can acquire the voltage parameters of the fuel cell in the fuel cell system and determine the adjusted health status parameters of the fuel cell based on the voltage parameters.

[0087] Step 203: If the health status parameters exceed the preset threshold range, change the opening frequency of the exhaust and drain valves of the fuel cell system within the first preset time range, and restore the fuel cell system to its initial state when the voltage values ​​of each individual cell in the fuel cell system are within the preset voltage range, or adjust the output power of the fuel cell system to the preset output power and the target altitude to the preset altitude when the voltage values ​​of each individual cell are not within the preset voltage range.

[0088] The preset threshold range can be determined based on the performance of the fuel cell stack. The first preset time range can be determined according to the actual application scenario. The initial state can be the normal operating state of the fuel cell system, which can be the state of providing the corresponding battery power output based on system requirements. The activation frequency can be the fast pulse activation frequency.

[0089] Specifically, if the health status parameters exceed a preset threshold range, the terminal changes the opening frequency of the fuel cell system's exhaust and drain valves within a first preset time range. Simultaneously, it records the battery voltage value of each individual cell in the fuel cell system. If the battery voltage value recovers to the preset voltage range, the fuel cell system is restored to normal operation. If the battery voltage value does not recover to the preset voltage range, a preset altitude for operation and a preset output power for the fuel cell system are determined based on the system's operating parameters. The system's operating altitude is then limited to the preset altitude, and the fuel cell system's output power is adjusted to the preset output power.

[0090] In addition, if the health status parameters do not exceed the preset threshold range, the terminal will restore the fuel cell system to its initial state.

[0091] In this embodiment, by determining that the hydrogen pressure sensor and / or air pressure sensor are faulty, the operating parameters of the fuel cell system are adjusted accordingly to ensure that the fuel cell system can still operate when the sensors fail, thereby achieving stable power output of the fuel cell system and improving the safety of the fuel cell system.

[0092] In an exemplary embodiment, the specific implementation process of step 201, "If the hydrogen infeed pressure value and / or air infeed pressure value are not within a preset range, and the fuel cell system does not meet the preset fault conditions, then determine that the hydrogen pressure sensor and / or air pressure sensor are faulty," may include:

[0093] If the hydrogen infeed pressure and / or air infeed pressure are not within the preset range, the components of the fuel cell system are checked for faults based on the preset fault strategy, and the fault check results are obtained. If the fault check results show that none of the components of the fuel cell system are faulty, and the first operating parameter corresponding to the target altitude is within the preset parameter threshold range, then it is determined that the fuel cell system does not meet the preset fault conditions, and that the hydrogen pressure sensor and / or air pressure sensor are faulty.

[0094] The components of the fuel cell system can include components for the hydrogen passage and components for the air passage. The hydrogen passage components can include at least a solenoid valve, a proportional valve, and a water distributor, while the air passage components can include at least an air compressor and a back pressure valve. The first operating parameter can be the operating parameter of the fuel cell system at the current altitude. This first operating parameter can include at least the air pressure value, hydrogen pressure value, air flow rate, and air compressor speed of the fuel cell system. The preset parameter threshold range can be determined based on the correspondence between altitude and parameters, or it can be determined based on the performance of the fuel cell.

[0095] Specifically, if only the hydrogen inlet pressure is outside the preset pressure range, it may indicate a malfunction in a component of the hydrogen pipeline or a problem with the operating parameters of that component. The terminal can then troubleshoot the relevant components of the hydrogen pipeline based on preset fault conditions to obtain the troubleshooting results.

[0096] If only the air inlet pressure is outside the preset pressure range, it may indicate a malfunction in a component of the air duct or a problem with the operating parameters of that component. The terminal can troubleshoot the air duct components based on preset fault conditions and obtain the troubleshooting results.

[0097] If the hydrogen and air inlet pressures are outside the preset pressure range, it may indicate a malfunction in the hydrogen and air pipelines or a problem with their operating parameters. The terminal can then troubleshoot the hydrogen and air pipeline components based on preset fault conditions to obtain the troubleshooting results.

[0098] If the troubleshooting results indicate that no components of the fuel cell system are faulty, and the first operating parameter corresponding to the target altitude is within the preset parameter threshold range, then the fuel cell system is determined not to meet the preset fault conditions. If only the hydrogen inlet pressure is outside the preset pressure range, then the hydrogen pressure sensor is determined to be faulty; if only the air inlet pressure is outside the preset pressure range, then the air pressure sensor is determined to be faulty; if both the hydrogen inlet pressure and air inlet pressure are outside the preset pressure range, then the hydrogen pressure sensor and / or the air pressure sensor is determined to be faulty.

[0099] In this embodiment, by judging whether the hydrogen inlet pressure value and the air inlet pressure value are within a preset pressure range, it is determined whether the hydrogen pressure sensor and / or air pressure sensor are faulty, thereby realizing fault detection of the hydrogen pressure sensor and air pressure sensor under high-altitude conditions and improving the safety of the system.

[0100] In one exemplary embodiment, the adaptive altitude operation method for aviation fuel cells further includes:

[0101] The single-cell voltage variance of the fuel cell system is determined based on the number of individual cells in the fuel cell system, the voltage value of each individual cell, and the average voltage value of the individual cells.

[0102] The difference between the average voltage value and the lowest voltage value of a single cell is determined as the lower deviation value of the fuel cell system.

[0103] The fuel cell system also includes a fuel cell stack, which may comprise multiple individual cells. Health parameters include at least the individual cell voltage variance and down-bias values ​​of the fuel cell system.

[0104] Specifically, the terminal can obtain the number of individual cells, the voltage value of each individual cell, and the average voltage value of each individual cell. Based on the number of individual cells in the fuel cell system, the voltage value of each individual cell, and the average voltage value of the individual cells, the single-cell voltage variance of the fuel cell system can be determined. The specific formula for calculating the single-cell voltage variance of the fuel cell system can be as follows:

[0105]

[0106] in, The voltage variance of a single cell; N is the number of single cells; u i denoted as , where is the voltage value of the i-th cell; μ is the average voltage value of the cell.

[0107] The terminal can determine the lowest voltage value of each individual cell from the voltage values ​​of each cell, and determine the difference between the average voltage value and the lowest voltage value of the individual cell as the lower deviation value of the fuel cell system. The terminal determines the individual cell voltage variance value and the lower deviation value as health status parameters of the fuel cell system.

[0108] Furthermore, the health status parameters of the fuel cell system determined in the above embodiments can all be determined using the method for calculating health status parameters in this embodiment. Health status parameters within a preset threshold range indicate that both the variance and lower deviation of the individual cell voltage are within the preset threshold range; health status parameters outside the preset threshold range indicate that the variance and / or lower deviation of the individual cell voltage are outside the preset threshold range.

[0109] In this embodiment, the health of the fuel cell system is assessed by calculating the variance and lower deviation of the voltage of each cell, so as to adjust the operating parameters of the fuel cell system.

[0110] In an exemplary embodiment, the specific implementation process of step 103, "determining the operating mode of the fuel cell system based on health status parameters," may include:

[0111] If the health status parameters do not meet the preset health conditions, the opening frequency of the exhaust and drain valves of the fuel cell system is increased within the second preset time range, and the voltage value of each cell in the fuel cell system is determined. If the voltage value of a cell is within the preset voltage range, the operating mode of the fuel cell system is determined to be the rising mode; if the voltage value of a cell is not within the preset voltage range, the operating mode of the fuel cell system is determined to be the cruise mode. Alternatively, if the health status parameters meet the preset health conditions, the operating mode of the fuel cell system is determined to be the rising mode.

[0112] The operating modes include ascending mode or cruise mode.

[0113] Specifically, if the variance and / or lower deviation of the voltage of a single cell in the fuel cell system are not within a preset threshold range, the terminal determines that the health status parameters do not meet the preset health conditions, and changes the opening frequency of the exhaust and drain valves of the fuel cell system within a second preset time range. While changing the opening frequency, the battery voltage value of each cell in the fuel cell system is recorded. If the battery voltage value recovers to the preset voltage range, the operating mode of the fuel cell system is determined to be the rising mode; if the battery voltage value does not recover to the preset voltage range, the operating mode of the fuel cell system is determined to be the cruise mode, and the system maintains the current operating altitude or reduces the current operating altitude.

[0114] In addition, if the health status parameters do not exceed the preset threshold range, the terminal determines that the health status parameters meet the preset health conditions and determines that the operating mode of the fuel cell system is ascent mode, and the system increases the operating altitude.

[0115] In this embodiment, by determining the health status of the fuel cell system, the operating mode of the fuel cell system can be adjusted, thereby improving the safety during operation.

[0116] In one embodiment, such as Figure 3 As shown, Figure 3This is a schematic diagram of a fuel cell system, which may include an air filter 301, an air compressor 302, an intercooler 303, an air pressure sensor 304, a fuel cell stack 305, a back pressure valve 306, a solenoid valve 307, a proportional valve 308, a hydrogen pressure sensor 309, a water distributor 310, and a return pressure sensor (not shown in the figure, but can be integrated on the water distributor 310).

[0117] In the fuel cell stack 305, the hydrogen source enters the fuel cell stack after passing through the solenoid valve 307 and the proportional valve 308.

[0118] The fuel cell stack forms a hydrogen circulation loop through the cooperation of the proportional valve 308 and the water distributor 310. At the same time, the component exhaust and drain valve of the water distributor 310 discharges the unfavorable impurities and water vapor from the fuel cell stack.

[0119] A hydrogen pressure sensor 309 is installed at the hydrogen inlet of the fuel cell stack to monitor the outlet pressure of the proportional valve and the hydrogen inlet pressure. An air pressure sensor 304 is installed at the air inlet of the fuel cell stack to monitor the outlet pressure of the air compressor and the air inlet pressure.

[0120] The backflow pressure sensor is located at the outlet of the distributor, i.e. the backflow inlet of the proportional valve, to monitor whether the exhaust and drain valve of the distributor assembly is blocked by ice under low-temperature conditions at high altitudes.

[0121] Air and hydrogen pressure sensors detect whether the fuel cell system is within the normal operating range, determine whether there is a fault in the fuel cell stack components or the pressure sensor itself, and provide corresponding handling measures.

[0122] Furthermore, the proportional valve is an integrated unit of a venturi tube and a proportional valve, with the outlet of the proportional valve serving as a nozzle. The water distributor is an integrated unit of a water distributor and an exhaust / drain valve. The opening degree of the proportional valve varies depending on the pressure at the front end of the proportional valve, the hydrogen inlet pressure, and the hydrogen consumption of the fuel cell stack. With a fixed air compressor speed and a fixed back pressure valve opening, the pressure rise of the air compressor is constant, meaning the ratio of the air compressor outlet pressure to the air compressor inlet pressure is constant.

[0123] The hydrogen circulation loop can also be constructed by integrating a proportional valve with a hydrogen circulation pump, or by integrating an ejector with a circulation pump.

[0124] In one embodiment, such as Figure 4 As shown, Figure 4 This is a flowchart of an adaptive altitude operation method for aviation fuel cells, which may include the following steps:

[0125] Step 401: Determine the target altitude of the current aviation fuel cell system.

[0126] Step 402: Determine the atmospheric pressure at the current altitude, the current operating current of the fuel cell system, the air flow requirement, and the operating speed and proportional valve opening of the existing air compressor, among other operating parameters.

[0127] Step 403: Compare the air compressor speed at the current target altitude with the preset speed threshold. If the air compressor speed is less than the speed threshold, the air compressor speed meets the preset increase conditions and the operating altitude is increased. Otherwise, proceed to step 404.

[0128] Step 404: If the air compressor speed exceeds the speed threshold, adjust the operating parameters of the fuel cell system, increase the back pressure valve opening and reduce the air compressor speed, and control the hydrogen-air pressure difference within the preset pressure difference range.

[0129] Step 405: Evaluate whether the individual cell voltage variance and down-deviation of the fuel cell system are within the preset threshold range. If the individual cell voltage variance and down-deviation are within the preset threshold range, the preset health condition is met, and the operating altitude is increased. Otherwise, proceed to step 406.

[0130] Step 406: If the single-chip voltage variance and lower deviation are not within the preset threshold range, briefly increase the opening frequency of the exhaust and drain valves, and at the same time detect the recovery of the single-chip voltage.

[0131] Step 407: Determine the relationship between the voltage of a single battery cell and the preset voltage threshold. If the voltage of a single battery cell recovers to within the preset voltage threshold, then increase the operating altitude; otherwise, proceed to step 408.

[0132] Step 408: If the voltage of a single chip does not recover to the preset voltage threshold range, the system will switch to cruise mode and no longer increase the altitude.

[0133] In one embodiment, under the harsh operating conditions of an aviation fuel cell system, particularly at high altitudes, pressure deviations and malfunctions may occur in the hydrogen inlet pressure and air inlet pressure sensors. To ensure stable performance output of the fuel cell system, the air inlet pressure can be reduced by adjusting the hydrogen proportional valve opening corresponding to the fuel cell stack operating current at different altitudes, thereby ensuring the supply of both hydrogen and air. Figure 5 As shown, Figure 5 This is a flowchart of an adaptive altitude operation method for aviation fuel cells, which may include the following steps:

[0134] Step 501: Determine whether the hydrogen inlet pressure value under the current proportional valve opening, the current air compressor speed, and the air inlet pressure value under the current back pressure valve opening are within the preset range. If not, proceed to step 502.

[0135] Step 502: Troubleshoot the air compressor, back pressure valve, and proportional valve. If no fault is found, proceed to step 503; if a fault is found, indicate the cause of the fault and provide a solution.

[0136] Step 503: If there is no fault, determine the current operating altitude of the aviation fuel cell system, and whether the operating parameters at that altitude, such as atmospheric pressure, fuel cell stack operating current, hydrogen inlet pressure, and airflow requirements, are normal. If the parameters are normal, proceed to step 504; if they are abnormal, indicate the cause of the fault and provide a solution.

[0137] Step 504: If the parameters are normal, then determine that there is a fault in the hydrogen inlet pressure sensor or the air inlet pressure sensor. Then set the proportional valve to the opening degree under the current altitude and current, and at the same time ensure that the back pressure valve is set to the current altitude and current. The air compressor meets the air flow requirements of the system.

[0138] Step 505: After changing the conditions, determine whether the variance and lower deviation of the voltage of a single cell in the fuel cell system are within the preset threshold range; if the variance and lower deviation of the voltage of a single cell are within the preset threshold range, the fuel cell system operates normally; otherwise, proceed to step 506.

[0139] Step 506: If the variance and lower deviation of the single cell voltage are not within the preset threshold range, briefly change the opening frequency of the exhaust and drain valves to perform rapid pulse opening and observe whether the single cell voltage recovers; if it does not recover, limit the altitude and fuel cell output power; if it recovers, proceed to step 507.

[0140] Step 507: If restored, the fuel cell system will function normally.

[0142] Based on the same inventive concept, this application also provides an adaptive altitude operation device for an aviation fuel cell to implement the adaptive altitude operation method for aviation fuel cells described above. The solution provided by this device is similar to the solution described in the above method. Therefore, the specific limitations of one or more embodiments of the adaptive altitude operation device for aviation fuel cells provided below can be found in the limitations of the adaptive altitude operation method for aviation fuel cells described above, and will not be repeated here.

[0143] In one exemplary embodiment, such as Figure 6 As shown, an adaptive altitude operation device 60 for an aviation fuel cell is provided, comprising: an acquisition module 61, an adjustment module 62, and a determination module 63, wherein:

[0144] Module 61 is used to acquire the operating parameters of the fuel cell system at the target altitude.

[0145] The adjustment module 62 is used to adjust the target operating parameters of the fuel cell system based on a preset adjustment strategy if the operating parameters do not meet the preset increase conditions, so as to obtain the health status parameters of the fuel cell system after adjustment.

[0146] The determination module 63 is used to determine the operating mode of the fuel cell system based on health status parameters.

[0147] In one embodiment, the adjustment module 62 is used to determine that the operating parameters do not meet the preset rise conditions and determine the preset adjustment strategy corresponding to the target altitude if the air compressor speed is greater than the preset speed threshold, and to adjust the air compressor speed and back pressure valve opening based on the preset adjustment strategy to obtain the adjusted air compressor speed and the adjusted back pressure valve opening.

[0148] Under the operating conditions of adjusted air compressor speed and adjusted back pressure valve opening, the health status parameters of the fuel cell in the fuel cell system are determined.

[0149] In one embodiment, the adjustment module 62 is also used to determine the hydrogen-air pressure difference based on the difference between the hydrogen inlet pressure value and the air inlet pressure value of the fuel cell stack in the fuel cell system.

[0150] If the hydrogen-air pressure difference exceeds the preset pressure difference threshold, the target operating parameters will not be adjusted.

[0151] In one embodiment, the adjustment module 62 is further configured to determine that the hydrogen pressure sensor and / or air pressure sensor are faulty if the hydrogen infeed pressure value and / or air infeed pressure value are not within the preset pressure range and the fuel cell system does not meet the preset fault conditions.

[0152] If a fault is found in the hydrogen pressure sensor and / or air pressure sensor, then in the first correspondence between opening and altitude, the first target opening of the proportional valve and the second target opening of the back pressure valve are determined based on the target altitude. In the second correspondence between speed and altitude, the target speed of the air compressor is determined based on the target altitude. The opening of the proportional valve is adjusted to the first target opening, the opening of the back pressure valve is adjusted to the second target opening, and the speed of the air compressor is adjusted to the target speed. The health status parameters of the fuel cell system are also determined.

[0153] If the health status parameters exceed the preset threshold range, the opening frequency of the exhaust and drain valves of the fuel cell system will be changed within the first preset time range. When the voltage values ​​of each cell in the fuel cell system are within the preset voltage range, the fuel cell system will be restored to its initial state. Alternatively, when the voltage values ​​of each cell are not within the preset voltage range, the output power of the fuel cell system will be adjusted to the preset output power and the target altitude will be adjusted to the preset altitude.

[0154] In one embodiment, the adjustment module 62 is further configured to perform fault diagnosis on the components of the fuel cell system based on a preset fault strategy if the hydrogen infeed pressure value and / or air infeed pressure value are not within a preset range, and obtain the fault diagnosis result.

[0155] If the troubleshooting results show that none of the components of the fuel cell system are faulty, and the first operating parameter corresponding to the target altitude is within the preset parameter threshold range, then it is determined that the fuel cell system does not meet the preset fault conditions, and that the hydrogen pressure sensor and / or air pressure sensor are faulty.

[0156] In one embodiment, the determining module 63 is further configured to determine the single-cell voltage variance of the fuel cell system based on the number of single cells in the fuel cell system, the voltage value of each single cell, and the average voltage value of the single cells.

[0157] The difference between the average voltage value and the lowest voltage value of a single cell is determined as the lower deviation value of the fuel cell system.

[0158] In one embodiment, the determining module 63 is configured to, if the health status parameters do not meet preset health conditions, increase the opening frequency of the exhaust and drain valves of the fuel cell system within a second preset time range, and determine the voltage value of each individual cell in the fuel cell system. If the voltage value of an individual cell is within a preset voltage range, the operating mode of the fuel cell system is determined to be a rising mode; if the voltage value of an individual cell is not within the preset voltage range, the operating mode of the fuel cell system is determined to be a cruise mode; or...

[0159] If the health status parameters meet the preset health conditions, the operating mode of the fuel cell system is determined to be the rising mode.
