Channel geometry (path length, dimension, shape) has a tremendous impact on PEMFC performance. Distributions of the reactant species concentration in a PEM fuel cell due to fuel consumption and local transport of water through the membrane can cause changes in current density, temperature and water concentration. Water distribution can lead to flooding or drying of the membrane that may shorten the PEMFC componets life. Finding a flow field pattern that distribute the gas more evenly is one method in minimizing these problems and optimising the PEM fuel cell performance. The paper presents the results obtained for a 100cm2 serpentine flow-field PEM fuel cell using Fluent software and Fuel Cell Module.
