[0002] At present, the application scenarios of fuel cells are mainly automotive power and marine power. The common characteristics of these scenarios are that fuel cells use hydrogen as fuel and air in the environment as oxidant, generate electricity through electrochemical reactions to drive the motor to rotate, convert the chemical energy of the fuel into electrical energy and then into mechanical energy to achieve power output, and directly discharge the anode and cathode exhaust gases and product water into the environment, thereby causing harm to the environment. In addition, the exhaust gas and product water also waste energy, so how to improve the exhaust gas utilization effect is the current research focus.

[0003] Traditional technology converts hydrogen produced by electrolysis components into electricity through fuel cells, and uses heat pumps to collect waste heat from fuel cells and supply it to the user end, realizing the simultaneous use of electricity and heat. However, in remote ocean and island environments, this method has a low utilization rate of hydrogen, which is easy to cause hydrogen waste, and the pure oxygen produced by electrolysis of water is difficult to transport outward, which is easy to cause oxygen waste, resulting in poor overall operating performance of the fuel cell.

[0060] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0061] The fuel cell operation control method provided in the embodiment of the present application can be applied to the application environment corresponding to the control process of hydrogen and oxygen in the fuel cell. Figure 1 The fuel cell system structure diagram shown in the system structure diagram, the terminal generates hydrogen and oxygen through electrolysis of a water electrolysis device, wherein hydrogen is transmitted to the fuel cell stack (i.e., the reaction chamber of the fuel cell) through a hydrogen storage device, a hydrogen regulating valve, and an anode solenoid valve, and oxygen is transmitted to the fuel cell stack through an oxygen storage device, an oxygen regulating valve, a cathode solenoid valve, and a cathode mixing chamber. Then the terminal filters the ambient air through an air filter, and then transmits the filtered ambient air to the cathode mixing chamber through an air compressor, an intercooler, and a one-way valve, where it is mixed with oxygen and then transmitted to the fuel cell stack. Among them, the oxygen transmitted by the water electrolysis device is pure oxygen, and the oxygen transmitted by the ambient air is impure oxygen.

[0062] After the fuel cell stack reacts with hydrogen and oxygen, the anode separates the remaining hydrogen and water vapor into a gas-water mixture through a gas-water separator to obtain hydrogen, which is then transferred to the fuel cell stack again through a hydrogen circulation pump for circulating hydrogen utilization treatment. The liquid separated by the gas-water separator is then transferred to the recovery water pool through the anode drain valve.

[0063] The system includes a cooling water subsystem, which transmits circulating water used to cool the temperature of the stack to the plate changer through a collision water tank and a cooling water pump, replaces the cooling water through the plate changer, cools the replaced cooling water through a fan, and then circulates it to the cooling device of the stack again through an electronic thermostat. The replaced cooling water can be transmitted to the user through a circulating water pump for the user's daily water needs.

[0064] The cathode passes through the gas-water separator, and transmits the separated oxygen to the ambient air through the back pressure valve, and transmits the liquid separated by the gas-water separator to the recovery pool through the cathode drain valve.

[0065] The system sends the electricity generated by the stack to the substation through the DCDC module for the daily electricity needs of users. The operation control method of the fuel cell is mainly used for the control process of the opening information of the cathode solenoid valve and the anode solenoid valve when hydrogen and oxygen are input into the stack. The control device for controlling the method can be a terminal, a server, or a system including a terminal and a server, and is realized through the interaction between the terminal and the server. Among them, the terminal can be but not limited to various personal computers, laptops, smart phones, tablets, etc. Among them, the terminal analyzes the opening information of the anode solenoid valve and the cathode solenoid valve through hydrogen data, oxygen data, and air compressor data, thereby controlling the rate of water electrolysis, so that the hydrogen and oxygen consumption of the stack is consistent with the hydrogen and oxygen yield of water electrolysis, thereby ensuring that the pure hydrogen and pure oxygen produced by water electrolysis can be consumed by the stack, and the waste gas produced by water electrolysis does not need to be treated in the system. Then, this solution controls the opening and closing of the drain valve and the pressure of hydrogen through the anode data and the anode pressure stabilization strategy, so that the hydrogen consumption of the anode system is basically equal to the hydrogen consumption of the fuel cell stack, which not only improves the hydrogen utilization rate, but also ensures the safety and reliability of the fuel cell without hydrogen leakage. Finally, compared with the existing technology, the air compressor only needs to provide the air flow corresponding to the cathode excess coefficient, which greatly reduces the air flow compared to the air flow required by the original air compressor, thereby reducing the power consumption of the air compressor. This solution not only avoids the generation of exhaust gas, reduces hydrogen leakage and hydrogen utilization, but also reduces the power consumption of the air compressor, so that there is no need to reuse the tail gas, so that all the converted electrical energy is used for the power generation power of the fuel cell, thereby comprehensively improving the overall operating performance of the fuel cell.

[0066] In one embodiment, Figure 1 As shown, a fuel cell operation control method is provided, which is described by taking the method applied to a terminal as an example, and includes the following steps:

[0067] Step S201, collecting hydrogen data, oxygen data, air compressor data, and anode liquid level data of water electrolysis, and identifying the hydrogen pressure of the hydrogen data, the oxygen capacity of the oxygen data, and the cathode excess air coefficient of the air compressor data.

[0068] In this embodiment, the terminal collects hydrogen output data of hydrogen through the induction device at the outlet of the hydrogen storage device set at the anode of the fuel cell to obtain hydrogen data, and collects oxygen output data of oxygen through the induction device set at the cathode and the air compressor to obtain oxygen data. Among them, the hydrogen data is the hydrogen fluctuation pressure data of the hydrogen output by the hydrogen storage device, and the terminal obtains the hydrogen pressure of the hydrogen data by calculating the average pressure value of the hydrogen fluctuation pressure data. The oxygen data is the oxygen flow data output by the oxygen storage device. The terminal calculates the sum of the oxygen flow data from the moment when the oxygen flow starts to be output to the current moment to obtain the oxygen capacity of the oxygen data. The air compressor data includes the cathode excess air coefficient preset by the staff, and the air flow data of the air compressor input to the fuel cell. The air flow corresponding to the air flow data is used to provide oxygen for the fuel cell. Among them, the hydrogen of this scheme passes through the hydrogen storage device at the anode, the hydrogen regulating valve and the anode solenoid valve and finally enters the stack (i.e., the reactor of the fuel cell), and the unreacted hydrogen in the stack re-enters the entrance of the stack by the stack gas-water separator and the hydrogen circulation pump. The oxygen in this scheme is provided by two parallel supply routes through the oxygen storage device, oxygen regulating valve, cathode solenoid valve and one-way valve. The other route is provided through the air filter, air compressor, intercooler and one-way valve. The specific hydrogen control process and oxygen control process will be described in detail later. Among them, the air compressor is used to provide air to the fuel cell, the hydrogen regulating valve is used to adjust the input rate of hydrogen input to the fuel cell, the anode solenoid valve is used to control the input flow of hydrogen input to the stack, and the cathode solenoid valve is used to control the input flow of oxygen input to the stack. Then the terminal collects the anode liquid level data through the water level sensing sensor. The anode liquid level data is the water level data in the drainage gas supply device (i.e., gas-water separator) that separates gas and water to prevent other gases from being discharged into the fuel cell. Finally, the terminal identifies the hydrogen pressure of the hydrogen data, the oxygen capacity of the oxygen data, and the cathode excess air coefficient of the air compressor data. Among them, the cathode excess air coefficient is the excess coefficient cathode excess coefficient λ preset by the staff in the fuel cell, and the cathode excess coefficient is used to calculate the size of the air flow that the air compressor needs to provide to the fuel cell.

[0069] Step S202, based on the anode liquid level data, identifying the control signal of the anode drain valve, and based on the control signal, identifying the hydrogen circulation gas supply mode of the fuel cell.

[0070] In this embodiment, the terminal identifies the control signal of the anode drain valve based on the anode liquid level data, and identifies the hydrogen circulation gas supply mode of the fuel cell based on the control signal. Among them, the control signal of the anode drain valve includes a drainage signal and a stop drainage signal, and the specific identification process will be described in detail later. Among them, the hydrogen circulation gas supply mode of the fuel cell is the specific gas supply time point of the hydrogen through drainage gas supply. The hydrogen circulation gas supply mode can recycle the hydrogen after the stack reaction by means of water sealing, and prevent the problem of hydrogen loss caused by leakage of hydrogen through the anode drain valve, thereby improving the utilization rate of hydrogen.

[0071] Step S203, based on the hydrogen pressure, through the anode pressure stabilization strategy, determine the anode solenoid valve opening information of the fuel cell, and collect the current output current of the fuel cell.

[0072] In this embodiment, the terminal determines the anode solenoid valve opening information of the fuel cell based on the hydrogen pressure and the anode pressure stabilization strategy, and collects the current output current of the fuel cell. The specific determination process will be described in detail later. The anode solenoid valve opening information is used to characterize the input flow of the anode solenoid valve to control the hydrogen input to the fuel cell stack.

[0073] Step S204, based on the current output current and the cathode excess air coefficient, the oxygen consumption of the fuel cell is calculated through the stack oxygen flow algorithm, and based on the oxygen capacity and oxygen consumption, the cathode solenoid valve opening information of the fuel cell is determined.

[0074] In this embodiment, the terminal calculates the oxygen consumption of the fuel cell based on the current output current and the cathode excess air coefficient through the stack oxygen flow algorithm, and determines the cathode solenoid valve opening information of the fuel cell based on the oxygen capacity and oxygen consumption. The cathode solenoid valve opening information is used to characterize the cathode solenoid valve to control the input flow of oxygen into the stack.

[0075] Step S205 , using the hydrogen circulation supply mode of the fuel cell, the opening information of the anode solenoid valve of the fuel cell, and the opening information of the cathode solenoid valve of the fuel cell as the operation control information of the fuel cell.

[0076] In this embodiment, the terminal uses the hydrogen circulation supply mode of the fuel cell, the opening information of the anode solenoid valve of the fuel cell, and the opening information of the cathode solenoid valve of the fuel cell as the operation control information of the fuel cell.

[0077] Based on the above scheme, the anode data and the anode pressure stabilization strategy are used to control the opening and closing of the drain valve and the pressure of hydrogen, so that the hydrogen consumption of the anode system is basically equal to the hydrogen consumption of the fuel cell stack, which not only improves the hydrogen utilization rate, but also ensures the safety and reliability of the fuel cell without hydrogen leakage. Finally, compared with the existing technology, the air compressor only needs to provide the air flow corresponding to the cathode excess coefficient, which greatly reduces the air flow compared to the air flow required by the original air compressor, thereby reducing the power consumption of the air compressor. This scheme not only avoids the generation of exhaust gas, reduces hydrogen leakage and hydrogen utilization, but also reduces the power consumption of the air compressor, so that there is no need to reuse the tail gas, so that all the converted electrical energy is used for the power generation power of the fuel cell, thereby comprehensively improving the overall operating performance of the fuel cell.

[0078] Optionally, based on the anode liquid level data, a control signal of the anode drain valve is identified, including: identifying the relationship between the anode liquid level data and a preset high liquid level threshold, and the relationship between the anode liquid level data and a preset low liquid level threshold; when the anode liquid level data is greater than the preset high liquid level threshold, a drain signal of the anode drain valve is generated, and when the anode liquid level data is less than the preset low liquid level threshold, a stop drain signal of the anode drain valve is generated.

[0079] In this embodiment, the terminal identifies the size relationship between the anode liquid level data and the preset high liquid level threshold, and the size relationship between the anode liquid level data and the preset low liquid level threshold. Then, when the anode liquid level data is greater than the preset high liquid level threshold, the terminal generates a drainage signal for the anode drain valve, and when the anode liquid level data is less than the preset low liquid level threshold, the terminal generates a stop drainage signal for the anode drain valve.

[0080] Specifically, the gas-water separator includes high and low liquid level sensors, wherein the high liquid level sensor is set at a preset high liquid level threshold position, and the low liquid level sensor is set at a preset low liquid level threshold position. The terminal determines the size relationship between the anode liquid level data and the preset high liquid level threshold and the preset low liquid level threshold by judging the sensing data of the high liquid level sensor and the sensing data of the low liquid level sensor. When water signals appear at the same time in the high and low liquid level sensors, the terminal generates a drainage signal for the anode drainage valve and controls the anode drainage valve to open, until there is no water signal at the low liquid level, the terminal generates a stop drainage signal for the anode drainage valve and controls the anode drainage valve to close.

[0081] Based on the above scheme, the gas-water separation is controlled by the liquid level to prevent hydrogen leakage through the anode drain valve, thereby improving the utilization rate of hydrogen.

[0082] Optionally, before identifying the hydrogen circulation supply mode of the fuel cell based on the control signal, it also includes: collecting the average single-chip voltage of the fuel cell and the minimum single-chip voltage of the fuel cell; when the average single-chip voltage is less than a preset minimum average single-chip voltage, or the minimum single-chip voltage is less than a preset minimum single-chip voltage threshold, identifying the first delay duration corresponding to the average single-chip voltage and the second delay duration corresponding to the minimum single-chip voltage; selecting the maximum delay duration from the first delay duration and the second delay duration, and based on the maximum delay duration, adjusting the generation time point of the stop drainage signal to obtain a new stop drainage signal.

[0083] In this embodiment, the terminal collects the average single-chip voltage of the fuel cell and the minimum single-chip voltage of the fuel cell. Then, when the average single-chip voltage is less than the preset minimum average single-chip voltage, or the minimum single-chip voltage is less than the preset minimum single-chip voltage threshold, the terminal identifies the first delay duration corresponding to the average single-chip voltage and the second delay duration corresponding to the minimum single-chip voltage. Finally, the terminal selects the maximum delay duration from the first delay duration and the second delay duration, thereby adjusting the generation time point of the stop drainage signal to obtain a new stop drainage signal. Among them, the first delay duration corresponding to the average single-chip voltage and the second delay duration corresponding to the minimum single-chip voltage are identified in the following manner: the terminal identifies the first delay duration corresponding to the average single-chip voltage and the second delay duration corresponding to the minimum single-chip voltage by querying the corresponding table of single-chip voltage and delay duration.

[0084] Specifically, when the terminal monitors that impurities accumulate in the hydrogen gas at the anode of the fuel cell stack, causing the average single-cell voltage (Vave) of the fuel cell stack to be less than or equal to the minimum average single-cell voltage (Vavemin), or the minimum single-cell voltage (VLo) of the fuel cell stack is less than the minimum single-cell voltage threshold (VLomin), the anode drain valve is opened to a low liquid level and then extended by Ns to remove the impurity gas and restore the fuel cell stack voltage to a normal level. The extended opening time Ns here is obtained by calibrating the average single-cell voltage (Vave) and the minimum single-cell voltage (VLo) and taking the larger value of the two by looking up the table.

[0085] Based on the above scheme, by identifying the average single-chip voltage of the fuel cell stack and the minimum single-chip voltage of the fuel cell stack, the delayed closing time of the anode drain valve is determined, so as to avoid hydrogen leakage while eliminating impurity gases in the fuel cell stack, thereby preventing the impurity gases from affecting the reaction efficiency of the fuel cell stack and reducing the hydrogen conversion efficiency.

[0086] Optionally, based on the hydrogen pressure, the anode solenoid valve opening information of the fuel cell is determined through an anode pressure stabilization strategy, including: collecting the target pressure of the anode, and determining the anode feedforward opening information of the fuel cell based on the target pressure; calculating the opening control information of the fuel cell through an anode pressure control algorithm based on the hydrogen pressure and the target pressure; determining the anode solenoid valve opening information of the fuel cell based on the anode feedforward opening information of the fuel cell and the opening control information of the fuel cell.

[0087] In this embodiment, the terminal collects the target pressure of the anode, and determines the anode feedforward opening information of the fuel cell based on the target pressure. Then, the terminal calculates the opening control information of the fuel cell through the anode pressure control algorithm based on the hydrogen pressure and the target pressure. Among them, the anode pressure control algorithm is the PID (Proportional, Integral, Differential) control algorithm of the fuel cell. Among them, the feedforward opening information is the initial opening size of the anode solenoid valve. It can be understood that since the pressure value in the stack is in a fluctuating state during the reaction process, in order to ensure that the hydrogen pressure and oxygen pressure in the stack maintain a stable ratio, the terminal always collects the pressure value of the stack, and calculates the target pressure of the anode based on the ratio of the pressure value of the stack to the hydrogen pressure and oxygen pressure that maintain a stable ratio. For example, the ratio of hydrogen pressure to oxygen pressure is 2:1, and the pressure value of the stack is F, then the target pressure of the anode is f 阳 =F*(2 / 3).

[0088] The terminal determines the anode solenoid valve opening information of the fuel cell based on the anode feedforward opening information of the fuel cell and the opening control information of the fuel cell, wherein the opening control information is used to adjust the feedforward opening information to ensure that the hydrogen pressure is stably maintained at the target pressure, so that the anode inlet pressure is stable.

[0089] Based on the above scheme, by controlling the hydrogen pressure stability and the target pressure, the hydrogen pressure at the anode is ensured to be stable, thereby increasing the hydrogen supply and oxygen supply to maintain a stable ratio, to ensure that the pure hydrogen and pure oxygen produced by water electrolysis can be consumed by the fuel cell stack, and there is no need to treat the waste gas produced by water electrolysis in the system.

[0090] Optionally, based on the oxygen capacity and the oxygen consumption, the cathode solenoid valve opening information of the fuel cell is determined, including: collecting the output current distribution information of a fixed time period, and replacing the current current value with each current value in the output current distribution information, returning to execute the step of calculating the oxygen consumption of the fuel cell based on the current output current and the cathode excess air coefficient through the stack oxygen flow algorithm to obtain the oxygen consumption distribution information; based on the oxygen capacity and the oxygen consumption distribution information, the cathode solenoid valve opening information of the fuel cell is calculated through the cathode pressure control algorithm.

[0091] In this embodiment, the terminal collects the output current distribution information of a fixed period, and replaces the current current value with each current value in the output current distribution information, and returns to execute the step of calculating the oxygen consumption of the fuel cell based on the current output current and the cathode excess air coefficient through the stack oxygen flow algorithm to obtain the oxygen consumption distribution information. Then, based on the oxygen capacity and the oxygen consumption distribution information, the terminal calculates the cathode solenoid valve opening information of the fuel cell through the cathode pressure control algorithm. Among them, the cathode pressure control algorithm is the same as the anode pressure control algorithm, and the input data is different.

[0092] Specifically, at the current output current I out A, the current cathode excess coefficient is λ. According to the current output current of the stack and the theoretical formula of the stack, the oxygen flow rate Q consumed by the stack can be calculated. Fuel , so the system needs to provide flow Q to the stack system =λ*Q Fuel This part of the flow is provided by the air compressor circuit and the cathode solenoid valve circuit in parallel.

[0093] Specifically, in the above scheme, the oxygen consumption is calculated by the current current value, thereby calculating the cathode solenoid valve opening information, thereby ensuring stable oxygen input, ensuring that the pure hydrogen and pure oxygen produced by water electrolysis can be consumed by the fuel cell stack, and there is no need to treat the waste gas produced by water electrolysis in the system.

[0094] Optionally, the method also includes: identifying the oxygen content of the air of the air compressor, and the corresponding relationship between the speed of the air compressor and the air flow, and calculating the target air flow distribution information of the air compressor based on the oxygen capacity, oxygen consumption distribution information, and the oxygen content of the air; based on the corresponding relationship between the speed of the air compressor and the air flow, identifying the ratio between the speed of the air compressor and the air flow, and based on the ratio and the target air flow distribution information, calculating the target speed value of the air compressor through an air speed pressure control algorithm.

[0095] In this embodiment, the terminal identifies the oxygen content of the air of the air compressor, and the corresponding relationship between the rotation speed of the air compressor and the air flow, and calculates the target air flow distribution information of the air compressor based on the oxygen capacity, oxygen consumption distribution information, and air oxygen content.

[0096] Then, the terminal identifies the ratio between the air compressor speed and the air flow based on the corresponding relationship between the air compressor speed and the air flow, and calculates the target speed of the air compressor through the air speed pressure control algorithm based on the ratio and the target air flow distribution information.

[0097] Specifically, the cathode solenoid valve circuit provides the oxygen flow Q consumed by the stack Fuel , which is half of the hydrogen flow consumed by the anode, thereby ensuring the consumption of pure oxygen produced by electrolysis of water. Since the hydrogen and oxygen consumption of the battery stack is consistent with the hydrogen and oxygen yield of electrolysis of water, the oxygen storage device and the hydrogen storage device can maintain a stable pressure. The air compressor circuit only provides an excess coefficient for the cathode circuit. Since there is only 20% oxygen in the air, the air compressor circuit flow is equal to Among them, the terminal presets the corresponding relationship between the speed of the air compressor and the air flow, and the terminal extracts the proportional coefficient in the corresponding relationship to obtain the proportional value between the speed of the air compressor and the air flow. Then, based on the proportional value and the target air flow distribution information, the terminal calculates the target speed value of the air compressor through the PID control algorithm of the fuel cell (see above for details).

[0098] Through the above scheme, the oxygen concentration of the cathode input stack is Generally, during the operation of the fuel cell, the cathode excess coefficient is λ, which is generally 1.5. The oxygen concentration of the new configuration is 42.8%, which is much greater than the 20% of the air-oxygen configuration, which helps to improve the efficiency of the fuel cell stack. Secondly, the original configuration cathode circuit needs an air compressor to provide , and the fuel cell configuration and control method based on oxygen ratio regulation, the air compressor only needs to provide Generally, during the operation of a fuel cell, the cathode excess coefficient λ is generally taken as 1.5, so the power consumption of the new configuration air compressor is equal to one third of the power consumption of the original configuration air compressor.

[0099] In another embodiment, the fuel cell further includes a cooling device, which is used to dissipate heat from the stack to prevent the stack from overheating and accelerating aging and decomposition. The control method of the cooling device is that when the cooling water temperature is lower than the low temperature threshold T1, the electronic thermostats are all switched to a small cycle, and the cooling water is rapidly heated by the PTC; when the water temperature is higher than the target temperature T2 and lower than the over-temperature threshold T3, the electronic thermostats are all switched to a large cycle, the cooling water is heat exchanged through the plate exchanger, the waste heat is recovered through the plate exchanger, and the water is heated and transmitted to the user through the circulating water pump. At this time, the temperature is closed-loop controlled by controlling the speed of the cooling water pump and the circulating water pump; when the water temperature is between T1 and T2, the electronic thermostat performs a closed-loop control of the opening according to the temperature sensor signal to ensure that the cooling water temperature can be quickly maintained at the target temperature T2, and the circulating water pump is not turned on at this time; when the cooling water temperature is higher than the over-temperature threshold T3, the cooling water pump and the circulating water pump reach the maximum speed under the operating power of the stack, and the fan is turned on to dissipate heat, so that the cooling water temperature quickly drops to the target temperature.

[0100] In another embodiment, the fuel cell also includes an energy supply device, which boosts the electricity generated by the fuel cell through DCDC and supplies it to high-voltage components, such as an air compressor, a hydrogen circulation pump, etc. The surplus electricity is connected to the substation through the line, and the substation transmits it to the user through conversion; the user's domestic water is heated by heat exchange with the stack cooling water through the plate heat exchanger, and the required temperature is controlled by external temperature control; the tail water of the cathode and the anode enters the recovery pool, and the water can continue to be used for water electrolysis and can also be used in the user's daily life.

[0101] Based on the above scheme, when supplying oxygen to the fuel cell stack, the oxygen consumption input to the fuel cell stack is controlled to be consistent with the oxygen output of electrolyzed water, thereby avoiding the waste of oxygen produced by water electrolysis and complicated processing procedures. At the same time, since the air compressor is only used to provide the excess coefficient of the cathode, the required air compressor speed will be greatly reduced, thereby reducing the system's accessory consumption and improving the system efficiency of the fuel cell. Finally, due to the increase in cathode oxygen concentration, the operating efficiency of the fuel cell stack is also improved.
