The invention relates to the technical field of hydrogen fuel cell electric vehicles, in particular to a vehicle hydrogen leakage treatment method and device, a vehicle and a storage medium, and the method comprises the steps that the actual hydrogen concentration in the vehicle is obtained; if the actual hydrogen concentration is larger than the preset safety concentration, it is judged that hydrogen leakage exists in the vehicle, and the hydrogen leakage level in the vehicle is matched according to the actual hydrogen concentration; and executing a corresponding preset hydrogen discharging action while executing an alarm action according to an alarm grade corresponding to the hydrogen leakage grade so as to reduce the actual hydrogen concentration in the vehicle to a preset safe concentration. Therefore, the problems that in the related technology, hydrogen leaks from a vehicle hydrogen system and enters a passenger compartment or a luggage compartment, so that danger is caused, the vehicle using safety is
