(1) Under the condition of 100% relative humidity, when the inlet pressure increases, the condensation rate and water content inside the fuel cell increase, and the pressure difference between the two sides of the membrane increases, which speeds up the transfer rate of protons on the membrane, increasing the electromotive force output by the fuel cells.(2)When the inlet relative humidity is 100%, the inlet temperature is 60 ℃, the inlet pressure is 10 kPa, and the current density is 260 mA/cm2, compared with the experimental values, the accuracy of water condensation rate model is about 21% higher than that of Fluent model. When the inlet pressure is 20 kPa, the water condensation rate model is about 31% higher than the Fluent model.
