摘      要：A water balance has a significant impact on the overall system performance in proton exchange membrane fuel *** actual fuel cell application has a dynamic electrical load which means also dynamic electrical ***,since this electrical current is known,the water production from the fuel cell reaction is also able to be *** long as the fuel cell water transportation model is provided,the present liquid water inside the porous medium is also able to be modeled.A model of the liquid water saturation level in a fuel cell in unsteady load condition was *** model is a series of the water transportation model of water saturation level for the final output of proton exchange membrane(PEM) fuel cell to predict the flooding or drying of PEM fuel *** simulation of vehicle fuel cell in different dynamic load profiles and different inlet air conditions was done using this *** simulation result shows that PEM fuel cell with different dynamic load profiles has different liquid water saturation level *** means that a dynamic load fuel cell requires also a dynamic input air humidification.
