The fuel cell is a conversion device which converts chemical energy in hydrogen and oxygen in air into electric energy through electrochemical reaction, and generates a large amount of water along with the electricity generation, wherein the generated water is mostly in a gas-liquid mixed state. The vigorous spread of fuel cell systems in medium and long haul heavy duty trucks is one of the important technical routes to achieve the national 'carbon neutralization, carbon peak-to-peak' strategic goals. Different from commercial vehicle scenes such as public transportation groups and the like which are vigorously developed at home and abroad in the last years, the operation environment and the road state of heavy-duty vehicles are relatively more severe. When the high-power fuel cell system is applied to heavy truck vehicles such as dump trucks, the high-power fuel cell system is always subjected to the working condition of large-angle inclination; the large-angle inclination condition increases the inclination angle of the fuel cell system, and further increases the gravity of the water inside the fuel cell stack 100, which affects the drainage. In view of this, embodiments of the present invention provide a fuel cell system control method, which aims to solve the above problems.
Referring to fig. 1, an embodiment of the present invention further provides a fuel cell system control apparatus, including: a fuel cell stack 100, an angle sensor 1, an air intake system 2, a hydrogen circulation system 3, and a hydrogen discharge system 4, and a fuel cell system controller 101;
the angle sensor 1, the air inlet system 2, the hydrogen circulating system 3 and the hydrogen discharging system 4 are all connected with the fuel cell stack 100;
the fuel cell system controller 101 is connected with the angle sensor 1, the air intake system 2, the hydrogen circulation system 3 and the hydrogen exhaust system 4;
wherein the angle sensor 1 is used for acquiring the inclination angle of the fuel cell system 100, and the fuel cell system controller 101 is used for controlling the air intake system 2, the hydrogen circulation system 3 and the hydrogen discharge system 4 according to the inclination angle so as to operate the fuel cell system 100 with high efficiency.
When the fuel cell system provided by the embodiment of the utility model is applied to a vehicle, due to the fact that different driving road conditions of the vehicle can generate an inclination angle, the fuel cell system can generate a certain inclination angle, when the inclination angle is too large, water generated in the fuel cell system cannot be discharged, and the problem of local flooding is caused, so that the inclination angle of the fuel cell system is obtained through the FCU, basic parameters of the fuel cell system are adjusted through the FCU according to the inclination angle, active adjustment of internal drainage of the fuel cell system is realized, and high-efficiency operation of the fuel cell system is ensured.
It should be noted that the FCU is a control "brain" of the fuel cell system, and mainly implements online detection, real-time control, and fault diagnosis of the fuel cell system, so as to ensure stable and reliable operation of the fuel cell system, and the FCU functions include gas circuit management, hydrothermal management, electrical management, communication function, fault diagnosis, and the like. The operating conditions, such as the pressure and humidity of the reaction gas, the internal humidity and temperature of the galvanic pile, directly affect the performance and the service life of the galvanic pile. Wherein, the gas circuit management function mainly realizes carrying out reasonable accurate control to the humidity of required hydrogen of fuel cell system and air, flow, pressure and temperature etc.. The water heat management function mainly realizes the control and regulation of the circulation, heating and heat dissipation of a cooling water channel and the temperature of air and cooling water, and improves the power of a fuel cell system and the reliability and stability of operation. The electrical management function mainly realizes the detection of the voltage and the current of the fuel cell system stack, adjusts the output power, controls the voltage of the fuel cell system in a reasonable interval, consumes the shutdown residual electric quantity, protects and controls the voltage and the current, and the like. The data communication function mainly realizes communication with other systems and interaction of important data information and control. The fault diagnosis function mainly realizes the functions of fault diagnosis, warning, alarming, protection and the like on all aspects of gas circuits, water heating, electricity, communication and systems.
The fuel cell system controller 101 adjusts the basic parameters of the fuel cell system in real time according to the inclination angle of the fuel cell system transmitted by the angle sensor 1, so as to realize the internal drainage of the fuel cell system and make the fuel cell system operate with high efficiency.
It can be understood that, when the vehicle is in a road condition with a large gradient or in a climbing stage, the inclination angle of the vehicle may become large, and since the inclination angle change rate of the vehicle may become large during the driving process of the vehicle, the inclination angle of the fuel cell system correspondingly disposed inside the vehicle may also become large, and the inclination angle change rate may also change together with the inclination angle change rate of the vehicle. The inclination angle of the fuel cell system is obtained through the angle sensor 1 and is transmitted to the FCU, and the FCU adjusts basic parameters of the fuel cell system according to the inclination angle of the fuel cell system, so that internal drainage of the fuel cell system is realized, and the fuel cell system can run efficiently.
It should be noted that the fuel cell system controller 101 adjusts the basic parameters of the fuel cell system according to the inclination angle to realize the internal water drainage of the fuel cell system, so that the fuel cell system operates with high efficiency, and the fuel cell system controller 101 controls the fuel cell system according to a preset program, without involving a new algorithm, that is, adjusting the air intake of the air intake system 2 or adjusting the hydrogen drainage of the hydrogen drainage system 4 by an angle, and the like, which are the existing technologies in the prior art.
As an example, the air intake amount of the fuel cell system is actively adjusted by the fuel cell system controller 101 before the flooding condition of the fuel cell system has not occurred, so as to avoid the water discharge burden of the fuel cell system from being increased due to too large air intake amount. It should be noted that the air intake amount can be determined by the current corresponding to the air intake amount and the preparation characteristics of the galvanic pile, and the air flow rate of the cathode side can be improved by adjusting the air intake amount, so that the situation that the cathode liquid water is too much and cannot be taken out of the galvanic pile is avoided.
As an example, the second hydrogen discharge valve 42 of the fuel cell system is actively adjusted to open before the fuel cell system is not flooded, and the air flow can be synchronously increased, and the partial air flow increase can dilute the tail discharge concentration and improve the water discharge efficiency in the fuel cell system stack.
It should be noted that the air amount, the air flow rate and the hydrogen discharge amount of the fuel cell system may be adjusted simultaneously, or only one or two of them may be adjusted, and the specific situation may be determined according to the needs, which is not limited in the embodiment of the present invention.
It should be noted that the apparatus provided in the embodiment of the present invention may implement the above-mentioned receiving, processing and comparing of the data transmitted by the angle sensor 1 based on the FCU itself, and perform the result processing according to the comparison result, that is, the implementation of the above-mentioned comparison step and control method does not involve any algorithm process.
In an alternative embodiment, the air intake system 2 comprises: an air pump 21, the air pump 21 being connected to the fuel cell stack 100.
In an alternative embodiment, the air intake system 2 further comprises a filter 22, the filter 22 is connected to the air pump 21, and the filter 22 is used for filtering out impurities in the air.
As an example, before the fuel cell system is not flooded, the air pump 21 is adjusted by the FCU, so as to actively adjust the air flow rate and the hydrogen discharge parameter of the fuel cell system, thereby reducing the hydrogen discharge amount of the fuel cell system and avoiding the waste of hydrogen.
In an alternative embodiment, the hydrogen discharge system 4 includes a first hydrogen discharge valve 41 connected to the cathode side of the fuel cell stack 100, and a second hydrogen discharge valve 42 connected to the anode side of the fuel cell stack 100.
When the inclination angle of the fuel cell system is not greater than the first threshold value, or the inclination angle change rate of the fuel cell system is not greater than the second threshold value, it is indicated that the inclination angle of the fuel cell system is not large, or the inclination angle change rate of the fuel cell system is not large, and the water discharge of the fuel cell system is not affected, at this time, the water discharge of the fuel cell system can be completed by adjusting the basic parameters of the fuel cell system through the FCU, and further, the water discharge can be performed by opening the second hydrogen discharge valve 42.
In an alternative embodiment, the apparatus further comprises a fuel supply, which is connected to the fuel cell stack 100.
When fuel needs to be supplied to the fuel cell system, the fuel supply unit is controlled by the FCU to operate, and fuel is supplied to the fuel cell stack 100.
