This work presents a three-dimensional fluid dynamic analysis of the gas channels of high temperature polymer electrolyte membrane fuel cells. Different patterns for gas flow field (pin-type, parallel channels, comb-type and multiple serpentine), as well as different channels geometrical characteristics are evaluated. The optimization of HT-PEM internal geometry is here performed accounting for overall pressure losses, gas distribution over the electrode area and residence time. In order to have a deeper understanding of the fluid dynamic field inside anode and cathode compartments and to identify the best channel design, the following geometrical parameters are considered: channel hydraulic diameter, active surface ratio, gas path.
