Abstract

The invention discloses a proton exchange membrane fuel cell energy management method, device, equipment and medium, and the method comprises the following steps: constructing a voltage decline model of a proton exchange membrane fuel cell according to an electrocatalyst active area degradation model in combination with attenuation loss of an effective catalyst active area; respectively solving the voltage recession model according to the typical voltage upper limit value to obtain each time sequence change data; and constructing an energy management fuzzy controller based on fuzzy logic according to the time sequence change data, and performing energy management on the proton exchange membrane fuel cell according to the energy management fuzzy controller. By designing the degradation model of the proton exchange membrane fuel cell ECSA, the life cycle cost of the proton exchange membrane fuel cell is further reduced, meanwhile, an energy management strategy based on fuzzy logic is combined with the cell degradation model, the calculation speed of the algorithm is further improved on the premise that the service life of the cell is guaranteed, and the calculation efficiency is improved. And the real-time performance of the algorithm is ensured while the energy is reasonably distributed.
