Abstract

The invention relates to a control method and device for loading power of a fuel cell system and electronic equipment. The method comprises the following steps: in the operation process of a fuel cell system, acquiring the current current density, the current proton exchange membrane state and the actual high-frequency impedance value of a fuel cell; based on a preset corresponding relationship among the current density, the proton exchange membrane state and the high-frequency impedance, determining a reference high-frequency impedance corresponding to the current current density and the current proton exchange membrane state; comparing the actual high-frequency impedance value with the reference high-frequency resistance value to obtain an impedance comparison result; under the condition that the impedance comparison result meets a first preset power control condition, acquiring a current loading power rate of the fuel cell system; determining a first target loading power rate of the fuel cell system based on the current loading power rate and a first preset rate adjustment rate; and adjusting the loading power of the fuel cell system based on the first target loading power rate. The performance and the service life of the fuel cell are improved.

Description

technical field [0001] The present application relates to the technical field of fuel cells, and in particular, to a method, device and electronic device for controlling the loading power of a fuel cell system. Background technique [0002] A fuel cell is a device that directly converts the chemical energy of fuel into electrical energy, and can be widely used in many fields such as mobile, fixed and portable auxiliary power systems, submarines, and space shuttles. [0003] Compared with traditional internal combustion engines, fuel cells have the advantages of high power density, high efficiency, and no pollution, and are one of the ultimate energy forms for future development. [0004] The limitation of the maximum power of the existing fuel cell system is to limit the maximum output power of the hydrogen fuel cell based on the calibration value, and it cannot be updated in real time according to the state of the stack, thereby causing the risk of excessive load on the fue...
