Abstract
A method for manufacturing a composite bipolar plate from a composition including at least one lamellar graphite and at least one thermoplastic polymer. This method includes dry sieving of the composition with a sieve for which the mesh diameter is less than or equal to 1,000 μm, dry blending of the sieved composition, deposition of the blended composition in a mold, this mold preferably being pre-heated, molding by thermocompression of the blended composition with induction heating of the mold, and removal from the mold of the thermocompressed composition leading to the obtaining of the composite bipolar plate. A composite bipolar plate manufactured by this method, to the use of this composite bipolar plate as well as to a fuel cell including such a composite bipolar plate.
