Leakproofing device for a fuel cell intended to be interposed between an Electrodes Membrane Assembly and a polar or bipolar plate of a fuel cell unit, the device consisting of a rigid frame and of a leakproofing seal integral with the frame, the frame furnished with the leakproofing seal defining a plurality of apertures through the device, the apertures being delimited by the leakproofing seal.

Leakproofing device for fuel cell, unit and fuel cell comprising such a device

A fuel cell plate includes at least one circulation channel for a reagent. The at least one circulation channel has an inlet communicating with a reagent distribution orifice formed through the plate. The plate also includes a reagent inlet collector orifice that is distinct from the reagent distribution orifice. The reagent inlet collector orifice supplies reagent to the inlet of at least one channel via a passage putting in fluid relationship the inlet collector orifice and the reagent distribution orifice, the inlet collector orifice extending longitudinally in the plane of the plate in a first longitudinal direction between a first bottom end and a second top end, the distribution orifice extending longitudinally in the plane of the plate in a second longitudinal direction between a first bottom end and a second top end, the first and second longitudinal directions being parallel to each other and vertical when the plate is in the vertical position of use, characterized in that, in the vertical position of use of the plate, the first bottom end of the inlet collector orifice is situated below the first bottom end of the distribution orifice.
