Dynamic humidity control method of hydrogen fuel cell and hydrogen fuel cell

The invention provides a dynamic humidity control method for a hydrogen fuel cell and the hydrogen fuel cell, and the method comprises the steps: obtaining a dynamic humidity control model based on a pre-constructed gas supply model and a gas flow required by a gas flow module; the gas flow of the reaction gas supplied to the gas flowing module by the gas supply module is adjusted by dynamically controlling the electromagnetic valve; the gas flow module controls the reaction gas to perform electrochemical reaction through an anode flow channel, a cathode flow channel and a pre-constructed gas flow model, and determines the running state of the hydrogen fuel cell; and controlling the humidifier through a preset fuzzy control algorithm according to the running state of the hydrogen fuel cell so as to control the humidity of the gas. According to the method disclosed by the invention, the hydrogen humidity of the hydrogen fuel cell can be accurately controlled, so that the hydrogen fuel cell reaches the highest
