Abstract
The invention concerns a monopolar fuel cell endplate () of the type with proton exchanging membrane consisting of a cathode or anode monopolar half-plate () attached to a closure plate (). The monopolar half-plate comprises, in its central part, a cathode or anode active region (), and, at its periphery, at least two oxidant boxes, if the monopolar half-plate is cathodic, or fuel boxes, if the monopolar half-plate is anodic. Each oxidant or fuel box comprises at least one channel () emerging outside the active region () to enable oxidant or fuel to be circulated outside the monopolar plate on the monopolar plate side, the oxidant or fuel boxes not comprising an opening emerging into the central region of the closure plate, such that the central part of said closure plate is not swept either with fuel or with oxidant.
