Abstract
The flow channel design dimensions significantly affect the performance of the proton exchange membrane fuel cell (PEMFC). In the present study, single-serpentine flow channel with four different types of channel widths is selected to evaluate their effect on performance of PEMFC. A complete three-dimensional PEMFC model was analyzed at 100% humidity conditions using ANSYS FLUENT-15.0. The serpentine channel with four different types of channel widths were compared at various range of pressures. It was noticed from the outcomes that at 4 bar operating pressure the fuel cell model attained the maximum performance and the fuel cell with 1 mm channel width best performance. The simulation results of serpentine flow field with optimum design parameters were in accordance with results in experiment.
