[0029] The display can be, for example, a touch screen type liquid crystal display (LCD) that can enable a user to interact with the user interface of the computer terminal 10.

[0030] During the operation of the fuel cell stack, a large amount of water is generated, and there is a large amount of water (water vapor) in the cathode and anode of the stack. Generally, the cathode water is directly discharged through the tail discharge pipeline, and the anode water is collected after being condensed into liquid water by the gas-liquid separator after being discharged, and then discharged when the anode drain valve is opened. The current fixed opening interval drainage strategy may, if the stack is operated for a long time, cause the phenomenon of water flooding of the stack. In view of the above technical problems, an embodiment of an anode drain valve control method of a fuel cell is provided. Figure 2 is a flowchart of the anode drain valve control method of the fuel cell according to the embodiment of the present application, as Figure 2 shown, the method comprises the following steps:

[0031] Step S202, detecting the requested power of the target vehicle.

[0032] ​In this step, the request probability of the target vehicle can be detected first. The target vehicle can be a fuel cell vehicle. The request power of the fuel cell vehicle (usually referred to as power demand or power requirement) refers to the electric power required by the vehicle under different operating conditions. This includes vehicle acceleration, climbing, driving on the highway, etc. The fuel cell system provides power to drive the electric motor, and this power demand varies according to the running state, load and driving conditions of the vehicle. Obtaining the request power of the target vehicle can be used to determine the current generated by the fuel cell in the target vehicle, and then determine the water production.

[0033] In step S204, the water production of the fuel cell system in the target vehicle is determined based on the request power.

[0034] In this step, according to the request power, the current generated by the fuel cell in the target vehicle can be determined, and then the water production can be determined. For example, the water production of the battery can be determined by understanding the basic chemical reaction and energy conversion efficiency of the fuel cell. The fuel cell generates water in the process of generating power, and the water production is related to the amount of electricity generated by the battery. The efficiency of the fuel cell can be estimated, and then the amount of hydrogen required can be calculated according to the power demand and the efficiency. Hydrogen and oxygen react in the fuel cell to generate electricity and water. Every 1 mole of hydrogen generates 1 mole of water. Through the chemical reaction equation, the amount of water generated per unit of power can be calculated. In this way, the water production of the fuel cell during operation can be roughly determined.

[0035] In step S206, the ambient temperature and humidity of the environment where the target vehicle is located are obtained.

[0036] In this step, the temperature and humidity of the environment where the target vehicle is located can be obtained by temperature sensor and humidity sensor. The temperature and humidity of the environment affect the water content in the air entering the fuel cell, and then cause the amount of water entering the water collection box. The related art does not consider the influence of the environment, and uses a fixed drainage interval strategy, which causes the waterlogging phenomenon to occur easily when the fuel cell stack is operated for a long time. For example, in the case of high environmental humidity, the air contains more water, and the opening interval can be appropriately shortened. In the case of low environmental humidity and high temperature, the air contains less water, and the opening interval can be appropriately extended.

[0037] In step S208, the water content of the air entering the fuel cell system is determined based on the ambient temperature and humidity.

[0038] In this step, according to the ambient temperature and humidity, the water content of the air entering the fuel cell system can be determined. The higher the humidity, the higher the water content in the air. The lower the humidity and the higher the temperature, the lower the water content in the air.

[0039] Step S210, based on the water content and water production, determine the amount of water in the target vehicle in the water collection box.

[0040] In this step, according to the water content in the air and the water production of the fuel cell system, the amount of water in the water collection box can be determined. Specifically, after the fuel cell system starts, according to the requested power of the whole vehicle, the stack works at a certain current point, and the humidity and temperature are obtained, the anode water production and the water content in the air under this operating condition are obtained. Specifically, the obtained water amount can be the mass of the water, which can be based on the density of the water to calculate the volume of the water, and then according to the volume of the water collection box to determine whether the water is too much at this time.

[0041] Step S212, in the case that the amount of water exceeds the first preset threshold, control the anode drain valve in the fuel cell system to open.

[0042] In this step, when the determined amount of water exceeds the first preset threshold, the anode drain valve in the fuel cell system can be controlled to open. The first preset threshold can be determined according to the actual situation. For example, the first preset threshold is set to two-thirds of the total volume of the water collection box, and the threshold is exceeded to consider opening the anode drain valve for drainage. When the opening time of the anode drain valve is determined, the influence of the environment of the target vehicle on the amount of water is considered, which can more accurately control the opening and closing of the valve and ensure the normal operation of the stack. Figure 3 The fuel cell system schematic diagram of the anode drain valve control method of the fuel cell according to the optional embodiment of the present application is provided, wherein the air enters the stack to generate chemical reaction to produce electric energy, and the temperature and humidity of the environment of the target vehicle will affect the water content in the air. The water produced by the reaction of hydrogen and air and the water in the air will enter the FWT (water collection box) for storage, and when the amount of water exceeds the first preset threshold, the FDV (drain valve) will be opened to drain the water.

[0043] Through the above steps, the purpose of adjusting the opening of the anode drain valve according to the actual situation is achieved, thereby realizing the technical effect of avoiding the flooding of the stack, and further solving the technical problem that the control strategy of using fixed opening time causes the influence of the temperature and humidity of the environment of the vehicle in the actual situation on the water in the water collection box, which may cause the flooding of the stack during long-term operation of the stack.

[0044] As an optional embodiment, based on the requested power, the water production of the fuel cell system in the target vehicle is determined, including: based on the requested power, the current generated by the fuel cell system is determined; based on the current, the water production of the fuel cell system in the target vehicle is determined.

[0045] Optionally, the energy conversion efficiency of the fuel cell system can be obtained. Because the fuel cell reacts hydrogen and oxygen to generate electricity. In this process, the energy conversion efficiency is usually less than 100%. Therefore, the energy conversion efficiency of the fuel cell needs to be considered. Then the power required by the fuel cell can be calculated according to the power demand of the vehicle and the efficiency of the fuel cell. Based on the power required by the fuel cell, the water production of the fuel cell system can be calculated, and the molar ratio of hydrogen, oxygen and water can be obtained according to the relationship between electricity and water, for example, according to the chemical reaction formula. According to the power and working time of the fuel cell, the amount of oxygen consumed can be calculated. Then the number of moles of water generated is calculated according to the molar ratio of oxygen to water. Finally, the number of moles is converted into the actual water volume or mass, so as to determine the water production of the fuel cell system in the target vehicle.

[0046] As an optional embodiment, based on the request power, the water production of the fuel cell system in the target vehicle is determined, including: determining the water production rate corresponding to the request power of the target vehicle according to the request power of the target vehicle in a preset time period; and integrating the water production rate corresponding to the request power in the preset time period to obtain the water production.

[0047] Optionally, because the request power changes during the operation of the target vehicle, the current generated by the fuel cell system also changes. Therefore, the water production rate corresponding to the request power of the target vehicle can be determined based on the request power of the target vehicle in a preset time period. Then the water production rate is integrated to determine the water production. The preset time period can be set according to the actual situation, but the preset time period should not be too long, because the water production is calculated every time the preset time period passes, and if the preset time period is too long, the accumulated water in the water collecting box will be too much, and the water flooding of the stack will occur.

[0048] As an optional embodiment, the environmental temperature and humidity of the environment where the target vehicle is located are obtained, including: detecting whether the request power of the target vehicle changes relative to the historical request power; and in the case that the request power of the target vehicle changes, obtaining the environmental temperature and humidity of the target vehicle again.

[0049] Optionally, the request power of the target vehicle can be detected based on whether the historical request power of the last time changes, and if it changes, the environmental temperature and humidity of the target vehicle can be obtained. That is, the temperature and humidity of the environment where the target vehicle is located can be obtained again every time the request power changes, and the water content in the air is calculated to improve the accuracy of the finally calculated accumulated water and better control the opening and closing of the anode drain valve.

[0050] As an optional embodiment, determining the amount of water accumulated in the water collection box of the target vehicle based on the water content and water production further includes: setting a preset time period; within the preset time period, detecting whether the requested power of the target vehicle has changed relative to the historical requested power; if the requested power of the target vehicle changes, acquiring the ambient temperature and ambient humidity of the target vehicle again, and determining the water production of the fuel cell system and the water content of the air introduced into the fuel cell system; and determining the amount of water accumulated in the water collection box within the preset time period based on the water content and water production within the preset time period.

[0051] Optionally, a preset time period can be set. Every preset time period, the water level in the collection box is determined, and then it is checked whether the water level exceeds a first preset threshold. If it does, the anode drain valve is opened. The preset time period should not be too long, because if it is too long, the water level in the collection box may exceed the first preset threshold before the judgment time, resulting in the fuel cell being flooded. Figure 4 This is a schematic diagram of the drainage control strategy of the anode drainage valve control method for a fuel cell provided by an optional embodiment of the present invention, wherein, after the system starts, the requested power P can be obtained first. a , in t a During the specified time period, the target vehicle's requested power is 'a'. At this time, the temperature 'Ta' and humidity 'RHa' of the target vehicle's environment are obtained. Based on the temperature and humidity, the air moisture content can be determined to be M1a. Based on the requested power 'a', the power at time t can be determined. a Current I generated during the duration a Based on the current, the water production capacity of the fuel cell system can be determined as M2a. Based on the water content in the air and the water production capacity of the fuel cell system, t can be determined. a The water accumulation within the time limit is Ma. When the requested power changes, the temperature and humidity can be obtained again for the above calculation. The requested power may change multiple times within the preset time limit, such as... Figure 4 As shown, there may be n changes. The total water production can be calculated by integrating the corresponding Mn (i.e., the corresponding water volume) for each of the n changes. The total water production can be considered as the amount of water that enters the collection box. During calculation, the obtained water volume can be multiplied by N to determine the total water volume, where N is the cathode-to-anode permeation rate. Then, it is determined whether the total water volume exceeds a first preset threshold. If it does, the anode drain valve can be opened to drain the water. The obtained water volume can be the mass of the water. The volume of the water can be obtained by dividing the total water production M by the water density ρ. It can be determined whether the volume of the water exceeds two-thirds of the collection box (the first preset threshold). If it does, the anode drain valve is opened.

[0052] As an optional embodiment, the drainage rate of the anode drainage valve is acquired; the amount of water to be drained is determined based on the second preset threshold and the amount of water; the target opening duration of the anode drainage valve is determined based on the amount of water to be drained and the drainage rate; and the anode drainage valve is closed when the opening duration of the anode drainage valve reaches the target opening duration.

[0053] Optionally, the drainage rate of the anode drainage valve can be acquired. The amount of water to be drained can be determined based on the second preset threshold and the amount of water, wherein the second preset threshold is the minimum liquid level in the water collecting box. In order to maintain the reaction in the fuel cell system, a certain amount of water is usually retained in the water collecting box to maintain a suitable humidity. Therefore, the amount of water to be drained after the anode drainage valve is opened this time can be determined based on the second preset threshold. Based on the amount of water to be drained and the drainage rate, the target opening duration of the anode drainage valve can be determined. When the opening duration of the anode drainage valve reaches the target opening duration, the anode drainage valve can be closed. The first preset threshold can be set to two-thirds of the volume of the water collecting box, and the second preset threshold can be set to one-third of the volume of the water collecting box.

[0054] According to the above method for calculating the opening interval of the drainage valve, the drainage interval can not be a fixed value. When the operating current is consistent, the operating environment is inconsistent, and the closing duration of the anode drainage valve can also be inconsistent. For example, in the dry northern winter and the rainy southern summer, the difference in operating water production can be solved by adjusting the opening frequency of the drainage valve. Considering the influence of environmental temperature and humidity on the anode water production rate, the influence of not timely drainage or over-drainage caused by using the same anode drainage rate in different operating environments is avoided.

[0055] It should be noted that, for the above-mentioned method embodiments, in order to simply describe, they are all expressed as a series of action combinations, but those skilled in the art should know that the present application is not limited by the described action sequence, because according to the present application, certain steps can be performed in other order or simultaneously. Secondly, those skilled in the art should know that the embodiments described in the specification all belong to preferred embodiments, and the actions and modules involved are not necessarily necessary for the present application.

[0056] Those skilled in the art can clearly understand the anode water drainage valve control method of the fuel cell according to the above-mentioned embodiments can be realized by means of software and the necessary general hardware platform, of course, it can also be realized by hardware, but in many cases, the former is a better embodiment.
