The invention provides a method and device for determining the air flow overshoot of a hydrogen fuel cell, a medium and equipment, and the method comprises the steps: obtaining parameter data of an effective period when the power of a hydrogen fuel cell system is subjected to step loading; determining an air flow error interval based on the target air in-pile flow and a preset error width; if it is determined that the response curve is a damped oscillation type curve, the current moment corresponding to the actual air in-pile flow falling into the air flow error interval for the first time is determined; determining overshoot based on the actual air in-reactor flow corresponding to each sampling moment and the maximum actual air in-reactor flow within the target time range; therefore, the air flow error interval can accurately represent the flow fluctuation interval of the air actual in-pile flow transitioning from the transient state to the steady state, on the basis, after the current moment is determined,
