Abstract
A bipolar plate structure for a fuel cell includes a cathode bipolar plate having a first flow field section to form cathode channels between the first flow field section and a first gas diffusion layer and a first land section to form coolant channels. An anode bipolar plate has a second flow field section to form anode channels between the second flow field section and a second gas diffusion layer and a second land section to form coolant channels. The cathode channels have an interdigitated channel structure, and the anode channels have a parallel channel structure. An air inlet manifold hole is formed along one of two long-side edge portions of a reaction region in the cathode and anode bipolar plates. An air outlet manifold hole is formed along the other of the two long-side edge portions of the reaction region.
