Device for adjusting humidity through coupling of intercooler and humidifier

The utility model discloses a device for adjusting humidity by coupling an intercooler and a humidifier, which relates to the field of hydrogen fuel cells and comprises a fuel cell stack and an air compressor, one side of the air compressor is sequentially connected with an air inlet flow meter and an air inlet air filter, and an air compressor controller is further arranged on the air compressor. According to the utility model, 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
