N2 - This study investigates the effects of stoichiometry, humidity, cell temperature, and pressure on the performance and the flooding of the proton exchange membrane fuel cell. Values of stoichiometry are 1.5, 2.0, and 2.5 at cell temperatures of 50, 55, and 60°C, respectively. This study shows that the dimensionless flooding value (FV) is a function of the stoichiometry, humidity, temperature, and pressure. The FV is calculated by using the measured values of temperature, humidity, pressure, and flowrate of the cathode. The effect of the dimensionless number on the flooding of the cathode in the proton exchange membrane fuel cell is analysed in this study. The effects of air stoichiometry, cell temperature, and air humidity are also discussed in this article.
