Summary: A numerical model of a PEMFC with serpentine flow field was set up in this study. Rectangular or triangular blocks were arranged in the cathode channel to improve cell performance. The results showed that the arranged blocks effectively enhanced reactant mass transfer and the triangular blocks performed better than the rectangular blocks. The blocks arranged in the rear of the turn exhibited the best cell performance, which was attributed to the combined effect of under-rib flow and secondary flow generated by the blocks.

Summary: This study investigated a fuel cell distributor with tree-like flow field plates through experiments and numerical simulations. The width scaling parameters were found to affect viscous dissipation, but were not directly related to improving PEMFC performance. Water accumulation and a slight increase in single PEMFC resistance were identified as the main reasons for decreased power density. Further improvements recommended reducing the number of branching generation levels and width scaling factor.
