The invention discloses an asymmetric humidification control system for a fuel cell. The asymmetric humidification control system comprises a fuel supply mechanism, an air supply mechanism, a fuel cell stack, a humidifier and a controller, wherein the fuel supply mechanism is communicated with the fuel cell stack through a first pipeline; the air supply mechanism is communicated with the fuel cell stack through a second pipeline; a humidification three-way valve is arranged on each of the first pipeline and the second pipeline; two humidifying pipelines are respectively connected between the humidification three-way valves on both of the first pipeline and the second pipeline and the fuel cell stack and pass through the humidifier; the humidifier can humidify materials in the two humidifying pipelines; and the humidification three-way valves and the humidifier are connected with the controller. The asymmetric humidification control system for the fuel cell is simple in structure, can perform asymmetric humidification on fuels and air, realizes cross humidification transformation, and therefore, can test the performance parameters of the fuel cell under cathode and anode asymmetric humidification conditions.
Description
technical field [0001] The invention relates to the field of fuel cells, in particular to a fuel cell asymmetrical humidification control system and working method. Background technique [0002] A fuel cell is a device that directly converts chemical energy into electrical energy (mainly hydrogen energy), and only electrochemical reactions occur without combustion. Because fuel cells directly convert chemical energy into electrical energy, breaking the Carnot cycle, their working efficiency is usually much higher than that of internal combustion engines and their energy density is high. The fuel cell can be used as an all-solid-state mechanical structure, that is, there are no moving parts, and it has high reliability and long life in a system where no relative motion occurs, and when the fuel cell uses hydrogen and air as fuel to generate water, it is pollution-free and Can be recycled. Due to the advantages of high efficiency, no pollution, no noise, long life and high r...
