In the technical scheme, the temperature in the shell, that is, the temperature of the operating environment of the fuel cell reaction device, needs to be obtained first, and when the temperature is low, especially when the temperature is lower than a first temperature threshold, the fuel cell system is not suitable for direct start, and the first temperature threshold refers to the lowest temperature suitable for normal start of the fuel cell system.
When the operating environment temperature of the fuel cell system is lower than the first temperature threshold, the performance of the fuel cell can be greatly reduced in a low-temperature environment, and liquid water in the electric pile and the fuel cell system can be frozen due to the fact that the liquid water is lower than the freezing point, so that the risk of starting failure exists.
Detect the fuel cell system and be in the cold start-up environment of low temperature, then at first control the compressor start, the third mouth is closed to the control valve body simultaneously, switch on the first mouth and the second mouth of valve body completely, at this moment, be equivalent to directly be connected the gas outlet of compressor with the casing, also can directly get into the casing through the high-temperature air of compressor compression, heat the pile that sets up in the casing, carry out rapid heating up to the reaction environment of fuel cell system pile, make the temperature can reach first temperature threshold fast.
The method is based on the fact that the air flow rate provided by the compressor at the rated rotating speed is far larger than the air flow rate required by the reactor reaction in the starting process of the fuel cell system, so that a large amount of high-temperature air which does not participate in the reaction can be introduced into the shell to heat the reactor. On the one hand, the air utilization rate of the pressurized compressor can be improved, the more important high-temperature air entering the shell can quickly improve the environment temperature of the electric pile, the time for low-temperature cold start of the fuel cell system is shortened, the cold start process of the fuel cell system is accelerated, and the use experience of a user is improved.

In the technical scheme, the temperature in the shell can be rapidly increased by heating the electric pile through high-temperature air, and when the temperature is greater than or equal to a first temperature threshold value, the fuel cell reaction device can be controlled to start. The opening degree of the second port and the opening degree of the third port of the valve body are adjusted according to the air inflow and the first air quantity by acquiring the air inflow of the compressor and the first air quantity required by starting the fuel cell reaction device, so that high-temperature air entering the shell is reduced, meanwhile, the third port is controlled to be opened, and the high-temperature and high-pressure air entering the fuel cell stack through the third port is processed to meet the requirement of the stack reaction of the fuel cell system.

In this solution, the fuel cell system is further provided with a bypass valve, and the air flow rate provided by the compressor at the rated rotation speed is much greater than the air flow rate required by the fuel cell system stack reaction during the starting process, so that the bypass valve needs to be added to discharge excess air outside the fuel cell system.
Specifically, after the fuel cell reactor is started, high-temperature and high-pressure air is not needed to enter the stack shell to heat the stack, and the second port needs to be closed to stop heating the stack.
After the second port is closed, the excessive high-temperature air can only pass through the third port, but the air flow required by the reactor reaction is limited, so that a bypass valve needs to be added to discharge the excessive air out of the fuel cell system to relieve the constantly-inrush air pressure and ensure the normal operation of the fuel cell system.
After the fuel cell system is stably operated, the rotation speed of the compressor is adjusted to control the supply of high-temperature air and the opening of the bypass valve is adjusted to discharge excess air to the outside of the fuel cell system, based on the intake air amount and a second air amount required for the operation of the fuel cell reaction device, that is, an air amount required for the stable operation of the fuel cell reaction and the stable output power.

In any of the above technical solutions, the method further includes: acquiring the ambient temperature of a fuel cell system; based on the environment temperature being greater than or equal to the second temperature threshold, the fuel cell system is started normally; based on the ambient temperature being less than the second temperature threshold, the temperature within the housing is obtained.
In the technical scheme, the temperature of the environment where the fuel cell system is located is firstly obtained, and when the environment temperature is greater than or equal to a second temperature threshold value, namely the environment temperature is higher, the fuel cell system does not need low-temperature cold start and can be started normally; when the ambient temperature is less than the second temperature threshold value, namely, the ambient temperature is cold, the temperature in the shell needs to be acquired, and the fuel cell system is subjected to low-temperature cold start.
A third aspect of the present invention provides a control device of a fuel cell system including: an acquisition module that acquires a temperature within the housing; and the control module controls the first port and the second port of the valve body to be communicated and the third port to be closed based on the temperature smaller than the first temperature threshold value, and controls the compressor to be started.
