The invention provides a humidification method of a fuel cell, computer equipment and a storage medium. The humidification method comprises the steps of periodically acquiring the output current density of a fuel cell; comparing the output current density with a first current density threshold value and a second current density threshold value, and judging the current density interval where the output current density belongs; when the output current density is smaller than or equal to the first current density threshold value, adopting a cathode recirculation system for humidifying the fuel cell; when the output current density is larger than the first current density threshold value and is smaller than the second current density threshold value, humidifying the fuel cell by utilizing an anode recirculation system; and when the output current density is larger than or equal to the second current density threshold value, humidifying the cathode of the fuel cell by utilizing a humidifier, and humidifying the anode of the fuel cell by utilizing the anode recirculation system, wherein the first current density threshold is smaller than the second current density threshold.
Description
technical field [0001] The invention relates to the technical field of proton exchange membrane fuel cells, in particular to a fuel cell humidification method, computer equipment and storage media. Background technique [0002] At present, global oil resources are becoming increasingly depleted, and environmental problems such as the greenhouse effect are becoming more and more serious. Compared with traditional internal combustion engines, electric motors and other power sources, fuel cells have great advantages in power density and environmental friendliness. A fuel cell is an electrochemical device that converts chemical energy directly into electrical energy. Since the energy conversion process of the fuel cell is not limited by the Carnot cycle, its energy conversion efficiency is relatively high. During the working process of the fuel cell, the fuel consumed is hydrogen, the reaction product is water, and the harmful emissions are zero, so it is one of the cleanest e...
