A bipolar plate assembly for a PEM fuel cell having a serpentine flow field formed on one side and interdigitated flow field formed on the opposite side such that a single plate member are usable for as an anode current collector and a cathode current collector of adjacent fuel cells. The bipolar plate assembly further includes a staggered seal arrangement to direct gaseous reactant flow through the fuel cell such that the seal thickness maximized while the repeat distance between adjacent fuel cells is minimized.
