Abstract
The humidity of the cathode air inlet of the proton exchange membrane fuel cell（PEMFC） stack has an important influence on the performance of the stack. The mathematical theoretical model of air-air humidifier is established, and moreover, the simulation model of the fuel cell humidifier and air system is developed based on Amesim software. From the fuel cell system level, the humidity change of the dry side outlet air is analyzed under different input conditions, including temperature, pressure, and water content on the dry and wet sides. The water transfer rate（WVTR） is employed to evaluate the humidification performance of the humidifier. The results show that the model can be used for verification in the early stage and well predict the dynamic response characteristics of the humidifier during the operation of the car.
