The invention relates to a bipolar plate (1) for a fuel cell comprising, on at least one of its faces, at least one groove capable of forming, together with the surface of an adjacent electrode, at least one fluid distribution channel. The bipolar plate (1), which is positioned, in essence, vertically, comprises essentially vertical channels (4) in which the flow of the fluids is ascending. The invention is characterized in that the diameter of the ascending channel (4) is slightly less than that of the channels where the flow is essentially downward (5) and horizontal. |
