Method for adjusting humidity through coupling of intercooler and humidifier

The invention discloses a method for adjusting humidity through coupling of an intercooler and a humidifier, and relates to the field of hydrogen fuel cells, a fuel cell stack and an air compressor are included, one side of the air compressor is sequentially connected with an air inlet flow meter and an air inlet air filter, and the air compressor is further provided with an air compressor controller. According to the invention, a system design scheme of coupling control of the intercooler and the humidifier is adopted, so that the humidity state of the outlet of the humidifier at the cathode side of the fuel cell system is changed into an adjustable humidifying performance band from a single curve; therefore, the slope of the demand curve of the original fuel cell stack for the relative humidity of the air cannot be overlapped with the performance curve of the humidifier, and the humidifier can cover the humidity demands of all working condition points of the same stack and the requirements of different work
