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.
