Problems solved by technology

[0002] In the related technology, the low-temperature cold start of the fuel cell system needs to use high-temperature air to heat the coolant, and then use the heated coolant to heat the stack. The heat is converted twice, and the heating efficiency is low.
Moreover, the specific heat capacity of water is relatively large, and the process of heating water by air is relatively slow, and the actual application effect is not ideal.

Abstract

The invention provides a fuel cell system, a control method and a control device thereof, and a vehicle. The fuel cell system comprises a fuel cell reaction device, wherein the fuel cell reaction device comprises a shell and an electric pile arranged in the shell, and the shell comprises an inlet; a valve body which comprises a first opening and a second opening; and a compressor, wherein an air outlet of the compressor is communicated with the first opening, and a second opening of the valve body is communicated with the inlet of the shell. On one hand, the utilization rate of air pressurized by the compressor can be improved, more importantly, high-temperature air entering the stack shell can quickly increase the environment temperature of the stack, the time for low-temperature cold start of a fuel cell system is shortened, the cold start process of the fuel cell is accelerated, and the use experience of a user is improved.

Description

technical field [0001] The present invention relates to fuel cells and their application fields, in particular, to a fuel cell system, a control method for the fuel cell system, a control device for the fuel cell system, a vehicle and a storage medium. Background technique [0002] In related technologies, the low-temperature cold start of the fuel cell system needs to use high-temperature air to heat the coolant, and then use the heated coolant to heat the stack, and the heat is converted twice, and the heating efficiency is low. Moreover, the specific heat capacity of water is relatively large, and the process of heating water by air is relatively slow, and the actual application effect is not ideal. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] To this end, a first aspect of the invention proposes a fuel cell system. [0005] A second aspect of the presen...
