Abstract: A valve includes a valve body provided with a plug, connected to an actuation system, an upstream duct, a downstream duct, and a purge duct provided with a shutter. The plug is movable in rotation about a longitudinal axis in the valve body, so that the rotation of the plug according to a first angular sector defines a flow between the upstream duct and the downstream duct, the rotation of the plug according to a second angular sector separate from the first angular sector shuts off the connection between the upstream duct and the downstream duct, and the rotation of the plug according to a third angular sector included in the second angular sector actuates the shutter so as to allow a flow from the upstream duct to the purge duct.

Abstract: A kit for forming a bipolar plate of a fuel cell, the kit comprising two half-plates (1A, 1B) adapted to be assembled one against the other, each of the two half-plates (1A, 1B) having grooves (11A, 12A, 11B, 12B) formed by embossing and extending in a longitudinal direction (X-X), and being adapted to form reagent flow channels (5A, 5B) on either side of the half-plates (1A, 1B), together with heat transfer fluid flow ducts (6) between the two half-plates (1A, 1B), the kit being characterized in that the half-plates (1A, 1B) are identical, each having at least one pair of complementary indexing elements (2A1, 2A2, 2B1, 2B2, 3A1, 3A2, 3B1, 3B2) made by embossing and adapted to center said half-plates (1A, 1B) relative to each other when they are assembled together.
