摘要：
The invention relates to a method for manufacturing a composite bipolar plate from a composition comprising at least one flake graphite and at least one thermoplastic polymer. Said method comprises the following consecutive steps: (a) dry sieving of the composition by means of a sieve for which the mesh diameters are less than or equal to 1000 μm, (b) dry blending of the sieved composition, (c) deposition of the blended composition in a mould, said mould preferably being preheated, (d) moulding by thermocompression of the blended composition with induction heating of the mould, and (e) removal from the mould of the thermocompressed composition leading to the obtaining of the composite bipolar plate. The invention also relates to a composite bipolar plate manufactured by said method, the use of this composite bipolar plate and a fuel cell comprising such a composite bipolar plate.
