monopolar terminal plate of a fuel cell and fuel cell comprising a plate of this type

摘要

monopolar endplate (4) of a fuel cell type proton exchange membrane, characterized in that it is constituted by a monopolar half (41) cathodic or attached to a decierre plate anode (42), the monopolar half comprising, in its central part, an active zone (411) cathodic or anodic and, on its periphery, at least two boxes (413) oxidizer, if the monopolar half is cathode or fuel, sila monopolar half is anodic, each comprising box oxidizer or fuel at least one channel (414) opening outside the active region (411) to permit flow of oxidizer or outside carburanteal monopolar plate on the side of the monopolar half, not comprising boxes comburenteo fuel openings which open into the central zone of the closure plate, so that the part centralde said closure plate may not be swept by the fuel or the oxidant or by.
