Performance of PBF‐Printed Micro‐Channel Bipolar Plates as a Function of Flow‐Field Parameters and Plane Area

Fuel Cells, Volume 26, Issue 3, June 2026.
ABSTRACT SUS 316L bipolar plates (BPPs) with rectangular micro‐channels for polymer electrolyte membrane fuel cell (PEMFC) were fabricated using powder bed fusion (PBF) technology, and the effects of flow‐field structure parameters (channel width, rib width, and channel depth) on fuel cell performance were analyzed.
