Experimental study of humidity changes on the performance of an elliptical single four-channel PEM fuel cell

Entropic Performance of Proton-Exchange Membrane through Current Density, Temperature, Pressure, Membrane Thickness and Humidity

“…[23] Which shows the factor of increasing the humidity produces a better voltage output compared to the ones with the lower humidity levels. In comparison to the two graphs, it was said by [23] that the increase in humidity at both ends increased the voltage output. However since the voltage output from the anodic side is much more vital for the fuel cell to operate, there needs to be a balance in the optimization of humidity to achieve the maximum output for the fuel cell [24].…”

“…The importance of humidity in the fuel cell is with the transmission of the hydrogen ion needing the presence of water molecules to be able to transfer through the PEM to the cathode side [23].…”

“…Effects of gas humidity variation in the cathode side [23] Figure 19. Effects of anode-side gas humidity variation [23] (Under the parameters of the rate of hydrogen and oxygen into the PEM is 0.5L/min, at the temperature of 55°C.)…”
