Abstract (en)
[origin: WO2017220552A1] In order to provide a bipolar plate (10) for a fuel cell having two profiled separator plates (12, 14) designed in such a way that the bipolar plate (10) has separate channels (28, 30, 32) for the reaction gases and the coolant, wherein the gas composition is incorporated in the active region, according to the invention, the channels (28, 32) for a reaction gas or both reaction gases have a smaller width (B2) in an inlet region (34) of the active region (16) than in the remaining sub-region (36) of the active region (16), wherein the width (B2) thereof continuously increases from the beginning to the end of the inlet region (34), while supports (54) between the channels (28, 32) have a greater width (B1) than in the remaining sub-region (36) of the active region (16), wherein the sum of the width (B2) of the channels and the width (B1) of the supports (54) is constant, and the width (B2, B2) of the channels (28, 32) and the supports (54) is constant in the entire remaining sub-region (36). The invention also relates to a fuel cell stack, a fuel cell system and a vehicle.
