Effect of Cell Potentials on Gas Diffusion Layer Velocity with Serpentine Flow Channel in PEM Fuel Cell

Authors(5) :-Dr.R.Rajappan, G. Gurunathan, P. Paramadhayalan, S. Purushothaman, R. Girimurugan

In this work, the influences of various cell voltages on the reactant gases velocity distribution at Gas Diffusion Layer (GDL)with conventional serpentine flow field in Proton Exchange Membrane Fuel Cell (PEMFC) is numerically studied. The six different cell potentials like (0.4, 0.5, 0.6, 0.7, 0.8 and 0.9V) were taken into account to optimize an effective velocity distribution of the reactant gases inside the cell at Gas Diffusion Layer. The numerical results show that the reactant gases distribution at GDL is enhanced with increases in cell potentials. Under the optimal fuel flow rate conditions, the PEM fuel cell with a cell potential of 0.6V provides the better velocity distribution of reactant gases at the Gas Diffusion Layer among the other five cell potentials.
