Fuel cell purging control method, device and equipment and readable storage medium

The invention provides a fuel cell purging control method, device and equipment and a readable storage medium, and the fuel cell purging control method comprises the steps: if the environment temperature is lower than a first preset temperature, obtaining the current vehicle speed when the shutdown of a fuel cell is detected; if the current vehicle speed is greater than the preset vehicle speed, purging an electric pile of the fuel cell by using a decompression purging mode; if the current vehicle speed is not larger than the preset vehicle speed, whether the power battery can continue to supply power independently or not is detected according to the remaining electric quantity of the power battery and the power consumption of the vehicle; if yes, when it is detected that the vehicle is powered off, a mixed gas purging mode is used for purging an electric pile of the fuel cell; and if not, purging the stack of the fuel cell by using a decompression purging mode. According to the invention, the electric pile o
