Abstract: 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.

Abstract: A fuel cell comprising at least one system consisting of anode (1) and of cathode (2) electrodes, an electrolyte (3) located between both electrodes and distributors (10,11) in the shape of plates located on either side of this system in contact with the electrodes for distributing the reagents, discharging the reaction products and collecting the current, the distributors consisting of electrically conducting plates adapted to allow the reagents flowing from one inlet to an outlet to come in contact with the electrodes, wherein each distributor in the shape of plates (10,11) consists of at least one stack of foils of porous material (13) adapted to form an arrangement in which the reactive gas flows in series over the foils.
