Simulation of Flow Field Manifold for PEM Fuel Cell

A model for simulating the flow field of a PEM fuel cell is presented. The effects of not only reaction and two-phase flow but also that of stoichiometric ratio on the flow-field of a fuel cell stack was studied. The aim is to highlight the importance of considering the above effects while doing a fuel cell system-level-analysis and design. These results help in better selection of the geometry to achieve uniform flow field and better evaluation of the pressure required to get the flow.
