Abstract
Description
Technical Field
[0001] This invention relates to the field of new energy, and in particular to a hydrogen fuel cell stack control system and method. Background Technology
[0002] A fuel cell is a device that converts the chemical energy of fuel (such as hydrogen) into electrical energy through an electrochemical reaction. In the context of clean energy, the application of fuel cell technology in vehicles is receiving increasing attention.
[0003] Hydrogen and oxygen undergo electrochemical reactions at the anode and cathode of the membrane electrode assembly (MEA), respectively, and their performance and power generation efficiency mainly depend on the catalytic activity of the MEA. However, in practical applications, the performance of hydrogen fuel cell stacks degrades after prolonged periods of inactivity, affecting user experience. Therefore, ensuring that the performance of hydrogen fuel cell stacks is not affected by prolonged storage has become a major challenge.
[0004] For the reversible degradation portion, the performance of the fuel cell stack can be restored through performance recovery measures (activation). Therefore, timely activation of the hydrogen fuel cell stack is an effective way to extend the lifespan of the fuel cell.
[0005] However, users cannot determine the aging level of a hydrogen fuel cell stack or when activation is necessary. Furthermore, hydrogen fuel cell stacks themselves lack unique identification, making it impossible to customize or control each individual stack.
[0006] Therefore, a novel hydrogen fuel cell stack control system and method are needed, which can label each hydrogen fuel cell stack and help users determine when to activate the hydrogen fuel cell stack. Summary of the Invention
[0007] In order to overcome the above-mentioned technical defects, the purpose of this invention is to provide a hydrogen fuel cell stack control system and method that, upon detecting performance degradation or based on historical experience calculations, notifies the user to activate the stack in a timely manner, thereby extending the lifespan of the stack.
[0008] This invention discloses a hydrogen fuel cell stack control system, including a fuel cell stack that provides electrical energy and a central control module. The central control module is electrically connected to the fuel cell stack to control the operating status of the fuel cell stack. The hydrogen fuel cell stack control system further includes a data module that stores the status information of the fuel cell stack.
[0009] The data module communicates with the central control module and sends status information to the central control module, enabling the central control module to generate control commands to control the operating status of the fuel cell stack based on the status information.
[0010] The status information includes static data and operational data of the fuel cell stack. When the fuel cell stack is activated, the data module updates the static data and operational data, calculates the next activation time based on the current activation data of the fuel cell stack, and sends the next activation time to the central control module.
[0011] The central control module generates a reminder command for the next activation time based on the next activation time, and sends a reminder signal before or at the next activation time.
[0012] Preferably, when the fuel cell stack is connected to an activation system for battery activation, the central control module records the activation information for each activation and writes the activation information into static data. The activation information includes activation time, activation duration, fuel cell stack electrical performance parameters before activation, and fuel cell stack electrical performance parameters after activation.
[0013] The central control module calculates the next activation time based on the activation time, activation duration, fuel cell stack electrical performance parameters before activation, and fuel cell stack electrical performance parameters after activation.
[0014] Preferably, the central control module calculates an activation interval Δt based on the following formula:
[0015] Where p% represents the electrical performance parameters of the fuel cell stack after activation, q% represents the electrical performance parameters of the fuel cell stack before activation, t2 represents the activation time during this activation, t1 represents the activation time during the previous activation, k represents the weight value, and n represents the cumulative number of activations.
[0016] The central control module sums the calculated activation interval time Δt with the activation time t2 during the current activation to obtain the next activation time.
[0017] Preferably, a lead time t3 is preset in the data module. When the data module receives the next activation time, it subtracts the lead time t3 from the next activation time to obtain a reminder time t4, and sends the reminder time t4 to the central control module.
[0018] The central control module sends an alert signal at the alert time t4.
[0019] Preferably, it also includes
[0020] The reminder element is electrically connected to the central control module. After receiving a reminder command, it displays a reminder signal, or
[0021] The control terminal communicates with the central control module and displays an alert signal after receiving an alert command.

[0024] The data module communicates with the central control module and sends status information to the central control module, enabling the central control module to generate control commands to control the operating status of the fuel cell stack based on the status information. The status information includes static data and operating data of the fuel cell stack.
[0025] Once the fuel cell stack is activated, the data module updates the static and operational data, calculates the next activation time based on the current activation data of the fuel cell stack, and sends the next activation time to the central control module.
[0026] The central control module generates a reminder command for the next activation time based on the next activation time, and sends a reminder signal before or at the next activation time.
[0027] Preferably, after the fuel cell stack is activated, the steps of updating static and operational data by the data module, calculating the next activation time based on the current activation data of the fuel cell stack, and sending the next activation time to the central control module include:
[0028] When the fuel cell stack is connected to an activation system for battery activation, the central control module records the activation information for each activation and writes the activation information into static data. The activation information includes activation time, activation duration, fuel cell stack electrical performance parameters before activation, and fuel cell stack electrical performance parameters after activation.
[0029] The central control module calculates the next activation time based on the activation time, activation duration, fuel cell stack electrical performance parameters before activation, and fuel cell stack electrical performance parameters after activation.
[0030] Preferably, the central control module calculates an activation interval Δt based on the following formula:
[0031] Where p% represents the electrical performance parameters of the fuel cell stack after activation, q% represents the electrical performance parameters of the fuel cell stack before activation, t2 represents the activation time during this activation, t1 represents the activation time during the previous activation, k represents the weight value, and n represents the cumulative number of activations.
[0032] The central control module sums the calculated activation interval time Δt with the activation time t2 during the current activation to obtain the next activation time.
[0033] Preferably, after the central control module sums the calculated activation interval Δt with the activation time t2 during the current activation to obtain the next activation time, it further includes:
[0034] A lead time t3 is preset in the data module. When the data module receives the next activation time, it subtracts the lead time t3 from the next activation time to obtain a reminder time t4, and sends the reminder time t4 to the central control module.
[0035] The central control module sends an alert signal at the alert time t4.

[0040] 1. Each hydrogen fuel cell stack has a digital identity or digital passport that records its own data, and the information stored on it can provide hydrogen fuel cell stack manufacturers with a large number of scalable functions.
[0041] 2. Users do not need to determine whether the hydrogen fuel cell stack needs to be activated; they can simply receive an automatic reminder to perform the corresponding operation.
[0042] 3. Control parameters stored in the digital identity, such as fan speed and hydrogen flow rate into the fuel cell stack, will be adjusted and updated after activation, thereby improving the vehicle's economy and power performance. Attached Figure Description

[0052] See Figure 1This is a schematic diagram of a control system for a hydrogen fuel cell stack according to a preferred embodiment of the present invention. In this embodiment, a hydrogen fuel cell stack control system is disclosed, including a fuel cell stack that provides electrical energy and a central control module. A fuel cell is a device that converts the chemical energy of fuel (such as hydrogen) into electrical energy through an electrochemical reaction. In the context of clean energy, the application of fuel cell technology in vehicles is receiving increasing attention. The central control module is electrically connected to the fuel cell stack to control its operating state. For example, the central control module can control the solenoid valves and fans of the hydrogen storage device to control the discharge rate of the fuel cell stack. To enable data-driven and precise recording and control of the fuel cell, the hydrogen fuel cell stack also includes a data module, which can be a digital chip installed within the fuel cell stack as a battery passport. The battery passport serves as the digital identity of the fuel cell stack and includes static data and operational data. The static data is primarily used for reference and control throughout the lifecycle of the fuel cell stack and generally does not change over a long period. For example, static data includes one or more of the following: basic information, material information, manufacturing information, distribution information, usage information, transfer information, recycling information, environmental impact information, and life cycle assessment information. Basic information includes one or more of the following: battery identification, battery type, manufacturer information, production location, production batch, individual cell information, chemical composition, battery weight, electrochemical performance, and recycling status. Operational data indicates the battery's operating status, such as output voltage, output current, charging time, discharging time, voltage, and charge during operation. The battery passport can identify specific targets and read / write relevant data, and has data storage capabilities. With the above data available, the data module communicates with the central control module, sending status information including static and operational data. Upon receiving this status information, the central control module generates control commands to change the operating status of the fuel cell stack, such as adjusting the fuel cell stack's output voltage, output current, and discharge time.
[0053] When the electrical performance of a fuel cell stack degrades, the reversible degradation can be restored through performance recovery measures (activation). The activation process typically has three characteristics: First, it usually operates the stack at a higher activation power than its rated power, requiring greater flow rates of fuel, oxidant (air), and coolant than at rated power. Second, the activation power typically increases gradually with a positive slope to the activation limit power. For a newly assembled stack, the initial activation power is approximately 20% of the rated power; for a stack undergoing reactivation, the initial activation can begin at 80%–100% of the rated power. Third, the activation limit power can be as high as twice the rated power. The activation process is complex, requiring equipment, manpower, and fuel. Furthermore, after a period of use and storage, changes in the water state on the internal membrane electrode assembly (MEA) can cause some proton conduction channels to lose activity, leading to performance degradation and necessitating reactivation. In this embodiment, after each activation, the system used for activation writes the activation data into the data module. The activation data includes, for example, the activation start time, the activation end time, the electrical performance of the fuel cell stack before activation, and the electrical performance of the fuel cell stack after activation. After activation, the data module updates its static and operational data based on the activation data and sends the updated static and operational data to the central control module. The updated static and operational data at least include the activation start time, activation end time, the electrical performance of the fuel cell stack before activation, and the electrical performance of the fuel cell stack after activation. The central control module calculates the next activation time based on the updated static and operational data. Alternatively, in another optional embodiment, the data module itself calculates the next activation time based on the updated static and operational data and sends this next activation time to the central control module. Once the central control module has the next activation time, it stores it and generates an activation reminder command. When the next activation time arrives, or a certain time before it arrives, it sends a reminder signal externally through interactive methods such as lighting a light or ringing a bell. Upon receiving the alert signal, users can promptly activate the fuel cell stack. With the configuration of the above technical solution, users no longer need to manually record each activation time or the next activation time, allowing for timely restoration of the fuel cell stack's electrical performance.
[0054] In a preferred embodiment, when the fuel cell stack is connected to an activation system for battery activation, the central control module records the activation information for each activation and writes the activation information into static data. The activation information includes activation time, activation duration, fuel cell stack electrical performance parameters before activation, and fuel cell stack electrical performance parameters after activation. It is understood that when the activation system is used to activate the fuel cell stack, the voltage monitoring module of the activation system will detect the individual cell voltage of the fuel cell stack, or a voltage sensor will be used to detect the output voltage of the fuel cell stack. All voltage data are compared and analyzed by the central control module to determine whether the reactivation of the stack is complete. Therefore, the activation information is recorded through the data forwarding process. The central control module calculates the next activation time based on the activation time, activation duration, fuel cell stack electrical performance parameters before activation, and fuel cell stack electrical performance parameters after activation.
[0055] More specifically, the central control module will calculate the next activation time based on the following process. The central control module contains the following calculation formula: An activation time interval Δt is calculated, where p% represents the electrical performance parameters of the fuel cell stack after activation, q% represents the electrical performance parameters of the fuel cell stack before activation, t2 represents the activation time during this activation, t1 represents the activation time during the previous activation, k is the weight value, and n represents the cumulative number of activations. The activation time interval Δt obtained in the above formula represents how long after the last activation the fuel cell stack should be activated again. (p% - q%) indicates the degree of improvement in the electrical performance parameters of the fuel cell stack by the previous activation, and also indicates the degree of decay of the electrical performance parameters of the fuel cell stack between the first two activations (if the expected electrical performance parameters are the same after each activation, for example, 90%). (t2 - t1) represents the decay rate of the electrical performance parameters of the fuel cell stack; the slower the decay, the less likely the expected time for the next activation is to be close; conversely, the faster the decay, the closer the expected time for the next activation should be. The weight value k can be adjusted according to the actual working conditions. When the activation frequency needs to be controlled at a low level, the weight value k can be set to a larger value, such as 1.5 or 2, to increase the activation interval time Δt. When the activation frequency needs to be controlled at a high level, the weight value k can be set to a smaller value, such as 0.6 or 0.8, to reduce the activation interval time Δt. This is another parameter that controls the activation frequency. The purpose of setting this parameter is that the more times the fuel cell stack is activated, the faster the stack will degrade, and the interval between two adjacent activations will correspondingly decrease, but it should not decrease too much. The settings allow for proper control of the subsequent activation time interval. After obtaining the activation interval Δt, the central control module sums the calculated activation interval Δt with the activation time t2 during the current activation to obtain the next activation time.
[0056] More preferably, if the fuel cell stack degrades faster than the device itself is designed to, then the activation reminder needs to be earlier. Therefore, a lead time t3 is preset in the data module. When the data module receives the next activation time, it subtracts the lead time t3 from the next activation time to obtain a reminder time t4, and sends the reminder time t4 to the central control module. The central control module then sends a reminder signal at the reminder time t4. The lead time t3 can be adjusted according to the desired advance time.
[0057] In any of the above embodiments, to facilitate the user's receipt of reminder signals, the hydrogen fuel cell stack control system further includes reminder elements, such as indicator lights, which are electrically connected to the central control module. Upon receiving a reminder command generated by the central control module, the indicator lights illuminate to display the reminder signal. Alternatively, a control terminal, such as a mobile phone or tablet, can be used. The control terminal is communicatively connected to the central control module. After receiving a reminder command, the user can open an application within the control terminal, and the application will display the reminder signal.
