[0025] In order to make the purposes, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application and are not all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, every other embodiment obtained by a person skilled in the art without creative work belongs to the scope of protection of the present application.

[0026] Firstly, the application scenarios applicable to the present application are introduced. The present application can be applied to the technical field of fuel cell power generation control.

[0027] It is found through research that at present, a solid oxide fuel cell (SOFC for short) is a new type of clean and efficient power generation equipment, has the advantages of wide fuel adaptability, etc., and can be widely used for efficient power generation of gaseous (methane, hydrogen), liquid, and solid (coal) fuels. The SOFC can directly and cleanly and efficiently convert chemical energy in the fuel into electrical energy without being limited by the Carnot cycle, so as to realize clean and efficient power generation of the fuel used for the SOFC.

[0028] However, in the process of generating power by the battery stack, the required reaction materials of the battery stack greatly change according to the temperature of the battery stack. In the process of controlling the temperature of the battery stack, the amount of the reaction materials in the battery stack greatly affects the power generation efficiency, and even causes the battery stack to be unable to work normally, resulting in structural damage.

[0029] Based on this, the embodiments of the present application provide a battery stack reaction control method, device, and equipment, so as to input appropriate reaction materials for power generation according to the temperature of the battery stack, ensure the power supply efficiency, and protect the fuel cell power generation stack.

[0030] Please refer to Figure 1 , Figure 1 The flowchart of the battery stack reaction control method provided by the embodiments of the present application is shown in FIG. 1. As shown in FIG. 1, the battery stack reaction control method provided by the embodiments of the present application includes the following steps. Figure 1

[0031] S101, detecting a temperature value of a fuel cell power generation stack in real time.

[0032] S102, determining a target flow control entry from a flow control table according to the detected temperature value of the fuel cell power generation stack.

[0033] ​The flow control table includes a plurality of flow control entries, each of which includes a preset working temperature value of the fuel cell power stack and a flow control value of the reaction material delivered to the fuel cell power stack at the working temperature value.

[0034] The reaction material can be fuel and air.

[0035] For example, the flow control entries can be air flow 0, fuel flow 0, temperature 0; air flow 0.5, fuel flow 0.5, temperature 30; air flow 1.0, fuel flow 1.0, temperature 50, etc.

[0036] It should be noted that the fuel cell power stack can be heated in various ways, such as electric heating, gas heating, etc.

[0037] S103, according to the target flow value in the target flow control entry, control the reaction material to be delivered to the fuel cell power stack according to the target flow value.

[0038] Specifically, the flow value of the reaction material delivered to the fuel cell power stack is adjusted based on each target flow control entry in the following way: find the target working temperature value of the fuel cell power stack closest to the real-time detected temperature value in the temperature adjustment direction from the target flow control entry; determine the target flow control value of the reaction material delivered to the fuel cell power stack corresponding to the found target working temperature value; control the reaction material to be delivered to the fuel cell power stack according to the target flow control value until the real-time detected temperature value of the fuel cell power stack reaches the target working temperature value.

[0039] For example, the flow control table includes a plurality of temperature control entries from zero degrees Celsius to six hundred and fifty degrees Celsius (six hundred and fifty degrees Celsius is the target temperature), the temperature difference between each flow control entry can be fixed, for example, 20 degrees Celsius is a temperature adjustment node, or it can be not fixed, it can be 10 degrees Celsius, 20 degrees Celsius, 30 degrees Celsius, etc. Each flow control entry also includes a preset flow of the reaction material to reach the target temperature.

[0040] For example, the target working temperature value is 650 degrees Celsius, and the current temperature of the fuel cell stack is 580 degrees Celsius. At this time, all the flow control entries between 580 degrees Celsius and 650 degrees Celsius in the temperature control table need to be found, for example, the temperature control entries between 580 degrees Celsius and 650 degrees Celsius include: air flow 70, fuel flow 70, temperature 590; air flow 72, fuel flow 72, temperature 605; air flow 75, fuel flow 75, temperature 650. After determining all the temperature control entries between 580 degrees Celsius and 650 degrees Celsius, first, control the air flow and the fuel flow to be 70, and when it is detected that the temperature in the fuel cell stack reaches the target temperature value 590 under the control entry, control the air flow and the fuel flow to be 72, and when it is detected that the temperature in the fuel cell stack reaches the target temperature value 650 under the control entry, control the air flow and the fuel flow to be 75, and when it is detected that the temperature in the fuel cell stack reaches the target temperature value 650 under the control entry, it is determined that the current temperature value of the fuel cell stack reaches the target working temperature value.

[0041] Specifically, after the temperature value of the fuel cell stack reaches the target working temperature value, the method further includes: determining whether the detected temperature value of the fuel cell stack reaches the target working temperature value; if yes, detecting the output current value and the output voltage value of the fuel cell stack in real time, and controlling the flow of the reaction material delivered to the fuel cell stack according to the detected output current value and the output voltage value of the fuel cell stack.

[0042] For example, when the temperature value of the fuel cell stack reaches the target working temperature value of 650 degrees Celsius, the current output current value is 50 A, and the output voltage value is 50 V. When it is detected that the output voltage value changes to 40 V and the output current value changes to 40 A, the current flow of the reaction material delivered to the fuel cell stack is reduced to the reaction material required when the output voltage value is 40 V and the output current value is 40 A.

[0043] In this way, after the temperature value of the fuel cell stack reaches the target working temperature, the flow of the reaction material input into the fuel cell stack continues to be adjusted according to the output current value and the output voltage value, so as to ensure that the fuel cell stack will not be affected by the lack or excess of reaction material to affect the power generation capacity.

[0044] Optionally, the method further comprises: in response to a reaction stop control signal for the fuel cell power stack, determining a plurality of temperature-reducing flow control entries from the flow control table according to the temperature value of the fuel cell power stack detected in real time, and when the temperature value of the fuel cell power stack reaches the working temperature value in a target temperature-reducing control entry, controlling the reaction material to be delivered to the fuel cell power stack according to the flow value in the target temperature-reducing flow control entry; and adjusting the flow value of the reaction material delivered to the fuel cell power stack according to each temperature-reducing control entry in sequence according to the stop control direction of the fuel cell power stack until the temperature value of the fuel cell power stack drops to zero, and then stopping the input of the reaction material into the fuel cell power stack.

[0045] Optionally, the method further comprises: in response to a reaction start control signal for the fuel cell power stack, determining a plurality of temperature-increasing flow control entries from the flow control table according to the temperature value of the fuel cell power stack detected in real time, and when the temperature value of the fuel cell power stack reaches the working temperature value in a target temperature-increasing control entry, controlling the reaction material to be delivered to the fuel cell power stack according to the flow value in the target temperature-increasing flow control entry; and adjusting the flow value of the reaction material delivered to the fuel cell power stack according to each temperature-increasing control entry in sequence according to the start control direction of the fuel cell power stack until the temperature value of the fuel cell power stack is higher than the highest working temperature value in the plurality of temperature-increasing control entries.

[0046] Optionally, the highest working temperature value in the plurality of temperature-increasing control entries is the target temperature value.

[0047] In this way, it is ensured that the fuel cell power stack will not work abnormally due to the sudden increase or disappearance of the reaction material during the start and stop of the fuel cell power stack.
