The invention relates to a purging control method and device for a fuel cell, a vehicle and a storage medium, and the method comprises the steps: collecting the environment parameters of the environment where the current vehicle is located when the fuel cell is in a purging mode, and obtaining the parking time of the current vehicle; calculating an initial nitrogen accumulation amount based on the environmental parameters and the parking duration, and calculating a total nitrogen accumulation amount in the circulation pipeline according to the initial nitrogen accumulation amount; and based on the total accumulation amount of the nitrogen, matching the optimal purging action of the fuel cell, and purging the nitrogen in the circulating pipeline according to the optimal purging action. According to the embodiment of the invention, the total nitrogen accumulation amount in the vehicle driving process can be intuitively and stably estimated, so that the vehicle is controlled to perform purging action, the hydrog
