[0053] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application. Figures 1-4 DETAILED DESCRIPTION

[0054] The embodiment of the present application discloses a fuel cell anode drainage control method for a carrier.

[0055] With reference to the accompanying drawings, Figure 1 A fuel cell anode drainage control method for a carrier, comprising the following steps:

[0056] Step S11, acquiring the movement parameters and environmental parameters of the carrier.

[0057] The movement parameters of the carrier include the movement posture of the carrier, the speed of the carrier, and the acceleration of the carrier, and the environmental parameters of the carrier include the environmental temperature and the environmental air pressure.

[0058] Before step S11, the following steps are further included:

[0059] The carrier controller collects the movement parameters and environmental parameters of the carrier in real time, and sends the movement parameters and environmental parameters to the fuel cell controller.

[0060] It should be noted that the movement posture of the carrier usually refers to the state of the three axes of the carrier relative to the selected reference system, and the earth is usually selected as the reference system; the movement posture of the carrier refers to the angle of the carrier relative to the selected reference system in each direction, and the environmental parameters of the carrier refer to the parameters of the environment around the carrier.

[0061] It should be noted that in step S11, the subject executing this step is the fuel cell controller.

[0062] It is understandable that the vehicle includes airplanes, cars, etc. Taking an airplane as an example, the airplane's movement attitude includes flight attitudes such as pitch, roll, and yaw. The airplane is equipped with various sensors such as satellite navigation, inertial navigation, flight attitude, and air traffic control speed. During the flight of the airplane, the airplane controller monitors the airplane's movement attitude, speed, acceleration, ambient temperature, and ambient air pressure through the above-mentioned sensors, and sends the monitored data to the fuel cell controller. The fuel cell controller receives the above data in real time and executes step S12.

[0063] Step S12: Obtain the output power of the fuel cell and determine the water production rate based on the output power and ambient temperature.

[0064] Specifically, the fuel cell controller acquires the output power q of the fuel cell and determines the water production rate Q of the fuel cell based on the output power q and the ambient temperature T of the carrier. in.water .

[0065] Understandably, the water production rate Q of a fuel cell... in.water =f1(q, T), when it is necessary to calculate the water production rate Q of the fuel cell. in.water At that time, the fuel cell controller inputs the fuel cell output power q and the ambient temperature T of the vehicle into the preset function f1, and then the water production rate Q of the fuel cell can be obtained. in.water .

[0066] It should be noted that the output power q of a fuel cell is related to the current operating conditions of the fuel cell. The output power q of the fuel cell will be different depending on the current operating conditions.

[0067] Step S13: Obtain the inner diameter of the drain valve and the gas pressure inside the distributor, and determine the drain valve's drainage rate based on the inner diameter, gas pressure, and ambient air pressure.

[0068] Specifically, the fuel cell controller obtains the inner diameter d of the drain valve and the gas pressure p in the distributor, and determines the drain rate Q of the drain valve based on the inner diameter d of the drain valve, the gas pressure p in the distributor, and the ambient gas pressure P. out.water .

[0069] Understandably, during the operation of a fuel cell, liquid water will continuously accumulate in the distributor. When the volume of liquid water reaches a certain level, the water in the distributor needs to be drained. At this time, the drainage rate of the distributor is related to the internal and external pressures of the distributor and the inner diameter of the drain valve, i.e., the water production rate Q of the fuel cell. out.water =f2(q, T), when it is necessary to calculate the water production rate Q of the fuel cell. out.waterWhen the fuel cell controller inputs the inner diameter d of the drain valve of the fuel cell, the gas pressure p in the water separator, and the ambient air pressure P into the preset function f2, the water production rate Q of the fuel cell can be obtained out.water .

[0070] It should be noted that the gas pressure p in the water separator is related to the current operating condition of the fuel cell. When the operating condition of the fuel cell does not change, the pressure at the inlet and outlet of the anode of the fuel cell can be regarded as a fixed vertical, and at this time the gas pressure p in the water separator can be regarded as a fixed value.

[0071] In step S14, the maximum water storage capacity of the water separator is determined according to the moving posture, the speed, and the acceleration.

[0072] Specifically, the fuel cell controller determines the maximum water storage capacity W of the water separator according to the moving posture of the vehicle, the speed v of the vehicle, and the acceleration a of the vehicle water .

[0073] It should be noted that the lowest point of the liquid level in the water separator is the inlet of the drain valve, and the highest point of the liquid level in the water separator is the water inlet of the water separator. If the lowest point of the liquid level in the water separator is lower than the inlet of the drain valve, the fuel (usually hydrogen) in the water separator will be discharged, and if the highest point of the liquid level in the water separator is higher than the water inlet of the water separator, the water in the water separator will flow back to the stack, affecting the normal operation of the fuel cell.

[0074] It can be understood that during the movement of the vehicle, the maximum water storage capacity of the water separator will change according to the moving posture, the speed, and the acceleration of the vehicle. The water separator is a component installed on the vehicle, so the moving posture, the speed, and the acceleration of the vehicle can be regarded as the moving posture, the speed, and the acceleration of the water separator. When the moving posture of the vehicle changes, the state of the water separator relative to the earth also changes. For example, when the aircraft is in a pitching flight posture and when the aircraft is in a rolling flight posture, the direction and angle of the water separator offset relative to the earth are usually different, and at this time the maximum water storage capacity W of the water separator water is also different. In addition, when the vehicle moves at a constant speed in a certain direction, the liquid level in the water separator is in a horizontal state, and when the vehicle accelerates or decelerates, the liquid level in the water separator is in an inclined state, so the speed v and the acceleration a also affect the maximum water storage capacity W of the water separator water .

[0075] In step S15, the opening time of the drain valve and the expected drain duration are determined based on the water production rate, the drain rate, and the maximum water storage capacity, and the drain is performed according to the opening time and the expected drain duration.

[0076] Specifically, the fuel cell controller determines the opening time of the drain valve and the expected drain duration based on the water production rate Q of the fuel cell in.water , the drain rate Q of the drain valve out.waterand the maximum water storage capacity of the water separator W water The opening time T of the drain valve and the predicted drain duration t are determined, and water is drained according to the opening time and the predicted drain duration.

[0077] It can be understood that the opening time T and the predicted drain duration t are both related to the water production rate Q in.water , the drain rate Q out.water of the drain valve, and the maximum water storage capacity W water of the water separator, that is, T = f4(Q in.water , Q out.water , W water ), t = f5(Q in.water , Q out.water , W water ), the opening time T can be calculated by the preset function f4, and the drain duration t can be calculated by the preset function f5.

[0078] In the above embodiment, in order to drain water, the fuel cell controller obtains the movement parameters and environmental parameters of the vehicle, then obtains the output power of the fuel cell, and determines the water production rate according to the output power of the fuel cell and the environmental temperature of the vehicle, then obtains the inner diameter of the drain valve and the gas pressure in the water separator, and determines the drain rate of the drain valve according to the inner diameter of the drain valve, the gas pressure in the water separator, and the environmental pressure of the vehicle, then determines the maximum water storage capacity of the water separator according to the movement posture, speed, and acceleration of the vehicle, and finally determines the opening time of the drain valve and the predicted drain duration based on the water production rate of the fuel cell, the drain rate of the drain valve, and the maximum water storage capacity of the water separator, and drains water according to the opening time and the predicted drain duration of the drain valve. Compared with the drain method of the background art, the present method realizes closed-loop control of fuel cell drainage by collecting and analyzing the movement parameters and environmental parameters of the vehicle, the drainage method is more accurate, and the fuel cell can be more effectively controlled to drain water, thereby improving the stability and reliability of the entire system.

[0079] Referring to Figure 2 , as a further embodiment of step S14, the maximum water storage capacity of the water separator is determined according to the movement posture, speed, and acceleration, specifically including the following steps:

[0080] Step S21: constructing a three-dimensional coordinate system according to the movement posture;

[0081] Step S22: determining the included angles a, b, and g of the movement direction of the aircraft with the x-axis, y-axis, and z-axis based on the three-dimensional coordinate system.

[0082] Step S23: determining the corresponding components v x , v y , and v z of the speed in the x-axis, y-axis, and z-axis directions based on the three-dimensional coordinate system.

[0083] Step S24, determining the corresponding components a x , a y , a z of the acceleration in the x-axis, y-axis and z-axis directions based on the three-dimensional coordinate system.

[0084] Step S25, inputting α, β, γ, v x , v y , v z , a x , a y and a z into a preset water storage capacity model to obtain the maximum water storage capacity of the water distributor.

[0085] It can be understood that the maximum water storage capacity of the water distributor is related to the offset angle, offset direction, speed and acceleration of the water distributor, that is, the maximum water storage capacity W water of the water distributor is equal to f3(α, β, γ; v x , v y , v z ; v z , a x , a y ), and the maximum water storage capacity W water of the water distributor can be calculated through the preset function f3.

[0086] In the above embodiment, in order to calculate the maximum water storage capacity of the water distributor, the fuel cell controller constructs a three-dimensional coordinate system according to the moving posture, then determines the included angles α, β, γ corresponding to the moving direction of the aircraft and the x-axis, y-axis and z-axis based on the three-dimensional coordinate system, determines the corresponding components v x , v y , v z of the speed in the x-axis, y-axis and z-axis directions based on the three-dimensional coordinate system, determines the corresponding components a x , a y , a z of the acceleration in the x-axis, y-axis and z-axis directions based on the three-dimensional coordinate system, inputs α, β, γ, v x , v y , v z , a x , a y and a z into a preset water storage capacity model, so as to obtain the maximum water storage capacity of the water distributor; since the water distributor on the carrier is in a moving state and has a certain moving posture, speed and acceleration, the maximum water storage capacity obtained by the above-mentioned manner is more accurate relative to the fuel cell which is always used statically, thereby improving the stability of the carrier powered by the fuel cell.

[0087] As a further implementation of the method, before obtaining the output power of the fuel cell and determining the water production rate according to the output power and the ambient temperature, further comprising the following steps:

[0088] Obtaining the moving posture of the vehicle, and determining whether the water inlet of the water segregator is higher than the water outlet of the water segregator according to the moving posture, if not, opening the drain valve.

[0089] Specifically, obtaining the moving posture of the vehicle, and determining the inclination angle and the inclination direction of the water segregator according to the moving posture; determining whether the water inlet of the water segregator is higher than the water outlet of the water segregator based on the inclination angle and the inclination direction of the water segregator, if the water inlet of the water segregator is lower than the water outlet of the water segregator, opening the drain valve, if the water inlet of the water segregator is higher than the water outlet of the water segregator, executing step S22.

[0090] It can be understood that the moving posture of the vehicle is usually complex, and the water inlet of the water segregator may be lower than the water outlet of the water segregator, at this time, the water segregator has no water storage capacity, and the water in the water segregator will flow back to the stack from the water inlet, affecting the normal operation of the fuel cell, therefore, when this state occurs, the drain valve needs to be opened to reduce the probability of backflow.

[0091] In the above embodiment, the fuel cell controller obtains the moving posture of the vehicle, and determines whether the water inlet of the water segregator is higher than the water outlet of the water segregator according to the moving posture of the vehicle, when the water inlet of the water segregator is lower than the water outlet of the water segregator, the drain valve is opened, thereby reducing the probability of water in the water segregator flowing back to the stack, and improving the stability of the fuel cell.

[0092] As a further implementation of the method, before obtaining the output power of the fuel cell and determining the water production rate according to the output power and the ambient temperature, further comprising:

[0093] Step S31, obtaining the current operating parameters of the fuel cell.

[0094] It can be understood that the operating parameters of the fuel cell include current data, voltage data, gas pressure of the anode and cathode, humidity of hydrogen, ratio of hydrogen and oxygen, etc.

[0095] Step S32, determining the output power of the fuel cell and the gas pressure in the water segregator according to the operating parameters.

[0096] In the above embodiment, the fuel cell controller obtains the current operating parameters of the fuel cell in real time, and determines the output power of the fuel cell and the gas pressure in the water segregator according to the current operating parameters of the fuel cell.

[0097] As a further implementation of the method, before obtaining the moving parameters of the vehicle and the environmental parameters, further comprising the following steps:

[0098] The vehicle controller acquires the movement parameters and the environmental parameters of the vehicle and sends the movement parameters and the environmental parameters to the fuel cell controller.

[0099] It can be understood that the fuel cell controller is mainly used for controlling the normal operation of the fuel cell, and the vehicle controller can acquire corresponding movement parameters and environmental parameters through various sensors on the vehicle and send the movement parameters and the environmental parameters to the fuel cell controller.

[0100] In the above embodiment, the vehicle controller acquires the movement parameters and the environmental parameters of the vehicle and sends the movement parameters and the environmental parameters of the vehicle to the fuel cell controller, and the fuel cell controller performs subsequent processing according to the movement parameters and the environmental parameters of the vehicle after receiving the movement parameters and the environmental parameters of the vehicle.
