The invention provides a method, device and equipment for determining the closed-loop response time of the air flow of a hydrogen fuel cell, and the method comprises the steps: carrying out the data analysis through an inflection point detection function, and accurately determining a starting inflection point and an ending inflection point of the air target in-pile flow in a power increasing stage of the hydrogen fuel cell; furthermore, the starting response time (the sampling time corresponding to the starting flow) of the actual air in-pile flow aiming at the power step load pulling and the ending response time (the sampling time corresponding to the ending flow) of the actual air in-pile flow aiming at the power step load pulling can be accurately determined; therefore, the closed-loop response duration of the air flow of the hydrogen-fired battery can be accurately determined; furthermore, the work such as model selection of a hydrogen fuel cell auxiliary system, pile parameter matching and optimization o
