Description

[0002] During the fuel cell stack reaction process, a continuous supply of reactant gases is required. The anolyte supplies hydrogen, and the cathode supplies oxygen. Due to the reaction characteristics of the fuel cell engine, the proton exchange membrane of the fuel cell stack needs to operate within a suitable pressure range to improve reaction efficiency. The hydrogen pressure in a fuel cell stack reaction is generally between 1 and 3 bar. However, to increase driving range and the total hydrogen storage capacity of the vehicle, the hydrogen tank pressure is as high as 700 bar. Therefore, from the hydrogen tank to the stack, numerous pressure reduction and safety protection components are required. Among them, the pressure reducing valve plays a crucial role in pressure reduction. Located at the outlet of the tank valve, the pressure reducing valve can reduce the pressure in the hydrogen tank from 700 bar to between 15 and 20 bar. However, due to its structure, the pressure reducing valve may not function properly under low temperature or prolonged shutdown conditions, causing the pressure downstream of the first-stage pressure reducing valve to gradually increase, seriously affecting the operation of the fuel cell stack.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0060] Figure 1 This is a circuit structure diagram of a fuel cell vehicle-mounted hydrogen storage system provided in an embodiment of the present invention. Figure 2 This is a schematic flowchart of a control method for an on-board hydrogen storage system for a fuel cell vehicle provided by an embodiment of the present invention, as shown below. Figure 1 and Figure 2As shown, this embodiment is applicable to the control of on-board hydrogen storage systems in fuel cell vehicles. This method can be executed by an on-board hydrogen storage system control device, which can be implemented in hardware and / or software and can be configured in a fuel cell vehicle. The on-board hydrogen storage system 100 includes at least: a pressure reducing valve 101, a medium-pressure sensor 102, and at least one hydrogen output unit 103. The hydrogen output unit 103 can be a hydrogen cylinder used to supply hydrogen to the fuel cell stack. A high-pressure sensor 104 is also provided between the hydrogen output unit 103 and the pressure reducing valve 101. The high-pressure sensor 104 is used to collect the pressure of the hydrogen output from the hydrogen output unit 103. A safety valve 105, a vacuum valve 106, and a one-way valve 107 are also provided on one side of the output end of the pressure reducing valve for the normal operation of the on-board hydrogen storage system 100. A hydrogen inlet shut-off valve 108 and a proportional valve 109 are sequentially installed between the output end of the fuel cell vehicle hydrogen storage system 100 and the fuel cell stack. The hydrogen gas output through the pressure reducing valve 101 passes through the hydrogen inlet shut-off valve 108 and the proportional valve 109 in sequence. The hydrogen inlet shut-off valve 108 is used to cut off, distribute and change the flow direction of hydrogen in the hydrogen pipeline, and the proportional valve 109 regulates the flow rate and flow direction of hydrogen in the hydrogen pipeline. Figure 1 The example configuration includes two hydrogen output units 103. The output terminals of the hydrogen output units 103 are connected to the input terminals of the pressure reducing valve 101, which is located at the outlet of the cylinder valve. During the fuel cell stack reaction process, it is necessary to continuously supply reaction gases to the fuel cell stack. The anode supplies hydrogen, and the cathode supplies oxygen. Due to the influence of the fuel cell engine reaction characteristics, the proton exchange membrane of the fuel cell stack needs to operate within a suitable pressure range to improve reaction efficiency. The hydrogen pressure in a fuel cell stack is typically between 1 and 3 bar. However, to increase driving range and vehicle hydrogen storage capacity, the hydrogen output unit 103 has a hydrogen storage pressure as high as 700 bar. Therefore, the hydrogen from the output unit 103 to the fuel cell stack must pass through numerous pressure reduction and safety protection components. Among these, the pressure reducing valve 101 plays a crucial role in pressure reduction. Located at the outlet of the cylinder valve, the pressure reducing valve 101 can reduce the pressure of 700 bar in the hydrogen output unit 103 to between 15 and 20 bar, ensuring that the hydrogen enters the fuel cell stack at its normal operating voltage. The output of the pressure reducing valve 101 is then sent to the fuel cell stack. The medium-pressure sensor 102 is used to collect the medium-pressure of the gas output from the pressure reducing valve 101, reflecting the pressure downstream of the pressure reducing valve 101. However, due to its structure, the pressure reducing valve 101 cannot function as a shut-off valve under low temperature or long-term shutdown conditions, which can cause the pressure downstream of the pressure reducing valve 101 to gradually increase. Therefore, the pressure downstream of the pressure reducing valve needs to be detected before the fuel cell stack starts working, and then the on-board hydrogen storage system of the fuel cell vehicle needs to be controlled accordingly. The control method for the on-board hydrogen storage system of the fuel cell vehicle includes:

[0061] S101, obtain the medium pressure value P.

[0062] The pressure of hydrogen gas at the output end of the pressure reducing valve, i.e., the medium pressure value P, is obtained through a medium pressure sensor.

[0063] S102, determine whether the medium pressure value P is within the first preset pressure range.

[0064] S103, if yes, output a delayed alarm signal and end the operation.

[0065] When the medium pressure value P is within the first preset pressure range, the medium pressure value P is temporarily within the normal range, and a delayed alarm signal is output, meaning that the fuel cell stack can start running first.

[0066] S104, if not, output a pressure fault signal or a fuel cell stack normal operation signal, and end the operation.

[0067] If the medium pressure value P exceeds the first preset pressure range, the pressure reducing valve may be in the normal pressure operating range and can output a normal operation signal for the fuel cell stack, allowing the fuel cell stack to operate normally; or the pressure reducing valve may be in low pressure and can output a pressure fault signal, shutting down the fuel cell stack and temporarily preventing it from starting up.

[0068] This invention obtains the intermediate pressure value downstream of the pressure reducing valve, then determines whether the intermediate pressure value is within the first preset pressure range, and then outputs different control signals accordingly to ensure that the on-board hydrogen storage system of the fuel cell vehicle is controlled and processed accordingly, so as to enable the normal start-up of the fuel cell stack.

[0069] Optional, Figure 3 A schematic diagram of the flow structure of another fuel cell vehicle-mounted hydrogen storage system control method provided by an embodiment of the present invention is shown below. Figure 3 As shown, the method includes:

[0070] S201, obtain the medium pressure value P.

[0071] S202, obtain the first pressure preset value P1 and the second pressure preset value P2, where P1 < P2.

[0072] S203, determine whether P1≤P≤P2.

[0073] In the fuel cell vehicle hydrogen storage system, a first pressure preset value P1 and a second pressure preset value P2 are preset, and the medium pressure value P, the first pressure preset value P1 and the second pressure preset value P2 are compared.

[0074] If S204 is the case, then output a delayed alarm signal and end the operation.

[0075] S205, if not, output a pressure fault signal or a fuel cell stack normal operation signal, and end the operation.

[0076] In this embodiment of the invention, by obtaining the medium pressure value downstream of the pressure reducing valve, determining the relationship between the medium pressure value P, the first preset pressure value P1, and the second preset pressure value P2, different control signals are output accordingly to ensure that the on-board hydrogen storage system of the fuel cell vehicle is controlled and processed accordingly, so as to enable the normal start-up of the fuel cell stack.

[0077] Optional, Figure 4 A schematic diagram of the flow structure of another fuel cell vehicle-mounted hydrogen storage system control method provided by an embodiment of the present invention is shown below. Figure 4 As shown, the method includes:

[0078] S301, obtain the medium pressure value P.

[0079] S302, obtain the first pressure preset value P1 and the second pressure preset value P2, where P1 < P2.

[0080] S303, determine whether P1≤P≤P2.

[0081] S304, if not, output a pressure fault signal or a fuel cell stack normal operation signal, and end the operation.

[0082] If S305 is the case, then output a delayed alarm signal.

[0083] S306, obtain the medium pressure value P again.

[0084] The hydrogen output unit continuously outputs hydrogen, and the medium-pressure sensor acquires the medium-pressure value P again.

[0085] S307, determine whether the medium pressure value P is within the second preset pressure range.

[0086] If S308 is the case, then output a normal operation signal for the fuel cell stack and end the operation.

[0087] If the medium pressure value P is within the second preset pressure range, that is, the current medium pressure value P is within the normal pressure range, then the fuel cell stack normal operation signal is output, and the fuel cell stack starts normally.

[0088] S309, if not, output a pressure fault signal and terminate the operation.

[0089] If the medium pressure value P is not within the second preset pressure range, it is considered that the pressure output by the current pressure reducing valve cannot meet the normal operation of the fuel cell stack. Therefore, a pressure fault signal is output, and the operation of the fuel cell stack is suspended.

[0090] This invention, after outputting a delayed alarm signal, acquires the medium-pressure value again, determines whether the current medium-pressure value is within the second preset pressure range, and then outputs different control signals accordingly to ensure that the on-board hydrogen storage system of the fuel cell vehicle is controlled and processed accordingly, so as to enable the normal start-up of the fuel cell stack.

[0091] Optional, Figure 5 A schematic diagram of the flow structure of another fuel cell vehicle-mounted hydrogen storage system control method provided by an embodiment of the present invention is shown below. Figure 5 As shown, the method includes:

[0092] S401, obtain the medium pressure value P.

[0093] S402, obtain the first pressure preset value P1 and the second pressure preset value P2, where P1 < P2.

[0094] S403, determine whether P1≤P≤P2.

[0095] S404, if not, output a pressure fault signal or a fuel cell stack normal operation signal, and end the operation.

[0096] If S405 is the case, then output a delayed alarm signal.

[0097] S406, obtain the medium pressure value P again.

[0098] S407, obtain the third pressure preset value P3, where P3 < P1.

[0099] S408, determine whether P3≤P≤P1.

[0100] In the fuel cell vehicle hydrogen storage system, a third pressure preset value P3 is set. The third pressure preset value P3 is less than the first pressure preset value P1. The intermediate pressure value P, the first pressure preset value P1 and the third pressure preset value P3 are compared to determine the current pressure state downstream of the pressure reducing valve.

[0101] If S409 is the case, output a normal operation signal for the fuel cell stack and end the operation.

[0102] S410, if not, output a pressure fault signal and terminate the operation.

[0103] When the fuel cell stack has been running for a period of time, the hydrogen in the pipeline is consumed, and hydrogen passes through the pressure reducing valve. The pressure reducing valve will then activate its overpressure regulation function, and the pressure downstream of the valve may return to normal. Therefore, after the fuel cell stack has been running for a while, the pressure downstream of the pressure reducing valve is reassessed. If the intermediate pressure value P is within the pressure range of P3 ≤ P ≤ P1, meaning the current downstream pressure is normal, a normal operation signal for the fuel cell stack is output, allowing the fuel cell stack to continue operating normally. If the intermediate pressure value P is not within the P3 ≤ P ≤ P1 range, then the pressure downstream of the pressure reducing valve is abnormal, and a pressure fault signal is output for inspection by personnel.

[0104] In this embodiment of the invention, after outputting a delayed alarm signal, the medium pressure value is acquired again. The current medium pressure value P, the first preset pressure value P1, and the third preset pressure value P3 are compared to determine the current pressure state downstream of the pressure reducing valve. Then, different control signals are output accordingly to ensure that the on-board hydrogen storage system of the fuel cell vehicle is controlled and processed accordingly, so as to enable the normal start-up of the fuel cell stack.

[0105] Optional, Figure 6 This is a schematic flowchart of a control method for an on-board hydrogen storage system for a fuel cell vehicle provided by an embodiment of the present invention, as shown below. Figure 6 As shown, the method includes:

[0106] S501, obtain the medium pressure value P.

[0107] S502, obtain the first pressure preset value P1 and the second pressure preset value P2, where P1 < P2.

[0108] S503, determine whether P1≤P≤P2.

[0109] S504, if not, output a pressure fault signal or a fuel cell stack normal operation signal, and end the operation.

[0110] If S505 is the case, then a delayed alarm signal will be output.

[0111] S506 outputs a normal operation signal for the fuel cell stack and obtains the fuel cell stack operating time T1.

[0112] S507, Get the preset running time T.

[0113] In this embodiment, a preset operating time T is included in the control system of the fuel cell vehicle hydrogen storage system. The preset operating time T can be selected according to actual design requirements, and no specific limitation is made.

[0114] S508, determine whether T1≥T.

[0115] S509, if not, then execute S506 again.

[0116] S510, if so, then obtain the medium pressure value P again.

[0117] Specifically, it is determined whether the fuel cell stack operating time T1 has reached the preset operating time T. If the fuel cell stack operating time T1 is greater than or equal to the preset operating time T, the intermediate pressure value P is obtained again to determine the downstream pressure of the pressure reducing valve. If the fuel cell stack operating time T1 is less than the preset operating time T, the fuel cell stack continues to react until the preset operating time is reached, and then the downstream pressure of the pressure reducing valve is determined.

[0118] S511, obtain the third pressure preset value P3, where P3 < P1.

[0119] S512, determine whether P3≤P≤P1.

[0120] S513, if yes, outputs a normal operation signal for the fuel cell stack and ends the operation.

[0121] S514, if not, output a pressure fault signal and terminate the operation.

[0122] In this embodiment of the invention, after outputting a delayed alarm signal, the operating time T1 of the fuel cell stack and the preset operating time T are obtained. Then, based on the reaction time of the fuel cell stack, the medium pressure value is obtained again to determine the current pressure state downstream of the pressure reducing valve. Then, different control signals are output accordingly to ensure that the on-board hydrogen storage system of the fuel cell vehicle is controlled and processed accordingly, so as to enable the normal start-up of the fuel cell stack.

[0123] Optional, Figure 7 This is a schematic flowchart of a control method for an on-board hydrogen storage system for a fuel cell vehicle provided by an embodiment of the present invention, as shown below. Figure 7 As shown, the method includes:

[0124] S601, obtain the medium pressure value P.

[0125] S602, obtain the first pressure preset value P1 and the second pressure preset value P2, where P1 < P2.

[0126] S603, determine whether P1≤P≤P2.

[0127] If S604 is the correct one, then output a delayed alarm signal.

[0128] S605 outputs a normal operation signal for the fuel cell stack and obtains the fuel cell stack operating time T1.

[0129] S606, Get the preset running time T.

[0130] S607, determine whether T1≥T.

[0131] S608, if not, then execute S605 again.

[0132] S609, if so, then obtain the medium pressure value P again.

[0133] S610, obtain the third pressure preset value P3, where P3 < P1.

[0134] S611, determine whether P3≤P≤P1.

[0135] S612, if yes, outputs a normal operation signal for the fuel cell stack and ends the operation.

[0136] S613, if not, output a pressure fault signal and terminate the operation.

[0137] S614. If the medium pressure value P is not within the range of P1≤P≤P2, then determine whether P>P2.

[0138] If the S615 is faulty, it will output a pressure fault signal and terminate the operation.

[0139] If the medium pressure value P is not within the range of P1≤P≤P2, it is determined whether the current medium pressure value P is greater than the second pressure preset value P2. At this time, the pressure downstream of the pressure reducing valve is in a high state, that is, the current overpressure has not been released. At this time, a pressure fault signal is output for the convenience of the staff to check.

[0140] S616, if not, then obtain the third pressure preset value P3, where P3 < P1.

[0141] S617, determine whether P3≤P≤P1.

[0142] S618, if not, outputs a pressure fault signal and terminates the operation.

[0143] S619, if yes, outputs a normal operation signal for the fuel cell stack and ends the operation.

[0144] If the intermediate pressure value P is not greater than the second preset pressure value P2, the third preset pressure value P3 is obtained again. It is then determined whether the intermediate pressure value P is between the first preset pressure value P2 and the third preset pressure value P3. If the intermediate pressure value P is not within the range of P3≤P≤P1, the pressure downstream of the pressure reducing valve is too low, and a pressure fault signal is output. If the intermediate pressure value P is within the range of P3≤P≤P1, the pressure downstream of the pressure reducing valve is within the normal operating range, and a normal operating signal for the fuel cell stack is output, and the fuel cell stack starts working normally.

[0145] In this embodiment of the invention, by obtaining the intermediate pressure value P downstream of the pressure reducing valve and the third pressure preset value P3, the relationship between the intermediate pressure value P and the third pressure preset value P3 is determined, and then different control signals are output accordingly to ensure that the on-board hydrogen storage system of the fuel cell vehicle is controlled and processed accordingly, so as to enable the normal start-up of the fuel cell stack.
