One of the methods of water management in PEM fuel cells is the humidification of gases, which has a great impact on the performance of the fuel cell. In this study, modeling of a membrane humidifier with moist air and for two gases, hydrogen and air on the dry side, and the effect of the flow rate on the dry and wet side on the moisture percentage of the dry side output, temperature dew point, water transfer rate and water recycling ratio were investigated. The results show that in a constant flow on the wet side, with an increase in the flow on the dry side, the dew point temperature difference in hydrogen and air decreases and the transfer rate and water recycling ratio increase. In a constant flow rate on the dry side, with an increase in the flow rate on the wet side, the dew point temperature difference in hydrogen and air increases and the transfer rate and water recycling ratio decrease.
