Abstract

Management of the water in the stack is a major problem in achieving optimal performance of a Proton Exchange Membrane (PEM) fuel cell. One of the problems caused by water imbalance in the PEM system is the formation of liquid water on the side of the cathode. High water content in the PEM fuel cell stack causes liquid water and flooding, and decreases its performance. The presence of liquid water on the cathode side of the fuel cell leads to a decrease in the amount of oxygen reacting in the catalyst layer. The results of this study indicate that a general increase in water content results in a decrease in the performance of PEM fuel cell systems. The highest water content occurs at a current density of 0.9, with Rha and RHc of 90%. In this condition, system performance is relatively stable at 0.67 volts, with 0.00016 gr/cm2 of liquid water content produced. Above this water content, system performance decreases significantly.
