Effect of Reactant Gases Velocity Distribution in Single Flow Channel High Temperature PEM Fuel Cell
Proton Exchange Membrane Fuel Cell (PEMFC) performance is decided by means of various design and operating parameters. Creation of water droplet on cathode side is reducing the penetration of hydrogen and oxygen gas in between the gas diffusion layer. So effective distribution of hydrogen and oxygen gases are resulting the reduced level of water droplet generation. In this study high temperature Proton Exchange Membrane Fuel Cell with single flow channel configuration is selected to investigate the effect of reactant gases velocity distribution at gas diffusion layer under the four different operating temperatures (463K, 473K, 483K, and 493K) by using COMSOL Multiphysics software. Result shows that the Proton Exchange Membrane Fuel Cell at an operating temperature of 493K gives the better reactant gases velocity distribution at gas diffusion layer among the other operating temperatures.
