The invention relates to a bipolar plate for a fuel cell comprising on at least one of its faces at least one flute able to form with the surface of an adjacent electrode at least one gas distribution channel, wherein said distribution channel has a shape or geometry such that the liquid of the biph
The invention relates to a bipolar plate for a fuel cell comprising on at least one of its faces at least one flute able to form with the surface of an adjacent electrode at least one gas distribution channel, wherein said distribution channel has a shape or geometry such that the liquid of the biphasic flow flowing in said channel may be moved away from said electrode surface. The invention also relates to a method for preparing such a bipolar plate and to a fuel cell comprising at least one of such bipolar plates.
