A fuel cell assembly 16~~ including bipolar plate assemblies (60, 64) on opposite sides of MEA (62). The MEA having anode (66), cathode (68), an electrolyte (70) and catalysts (74, 76) each disposed between the electrolyt e and a respective gas diffusion layer (78). The bipolar plates having flow fields (87), namely anode flow fields 88~ and cathode flow fields 90~, with the flow fields having one or more channels (92) defined at least in part by sidewalls (94) and bottom (96). |
