Abstract: Channel's height-width ratio played a significant role on the HT-PEMFC's performance. In the current study, a rectangular parallel flow field design was used to analyze the three different ratios between the channel height-width to observe the various factors that includes velocity field vectors, pressure and water mass fraction in the anode and cathode compartments, membrane current density, the mass fraction of H2, N2 and O2, also polarization curve for HT-PEMFCs. In the first ratio 1:1 where the height and width of gas channel remains the same. By keeping the same channel's inlet-outlet area, the height in the second ratio (4:5) is smaller than the width, while the height in the third ratio (5:4) is larger. Using the COMSOL 6.0 Multiphysics software, we performed a numerical simulation modelling of the HT-PEMFC for this investigation. When channel height to width is kept at (1:1) shows good performance for polarization plot simulation results.
