Bipolar plates in the fuel cells are mechanical components chiefly responsible for power variation and even distribution of fuel and oxidant at the membrane exchange assembly. To ensure the fuel cell optimal performance and longevity of the membrane the flow field pressures need to be in the optimum range. In this study, a combination of existing and new designs of bipolar plate flow Fields for 100 × 100mm area membrane exchange assembly Size have been modelled and studied with the help of computational fluid dynamics. A total of six variant designs have been analyzed. An attempt is made to understand the most efficient channel design which results in a good flow field & low-pressure drop. The simulation studies indicate that the serpentine channel with two channels-opposite inlets-outlets provides the most uniform pressure drop and the best fuel distribution and is 10% better than the serpentine conventional single-channel bipolar plate Flow fields.
