A bipolar plate for a fuel cell, the bipolar plate comprising a fiber reinforcement structure including thermoplastically bonded carbon fibers, the fiber reinforcement structure being multilayered and comprises a plurality of fiber reinforcement structure layers, at least two of the fiber reinforcement structure layers having thermoplastically bonded carbon fibers.
A method for manufacturing a bipolar plate, the method comprising the steps of:
- a) providing a multilayered fiber mixture comprising carbon fibers, preferably in the form of a fiber tangle, and binding fibers having a thermoplastic plastic, wherein at least two fiber mixture layers include carbon fibers,
- b) heating of the fiber mixture above the melting point of the binding material, and thus melting of the binding fibers,
- c) placing the fiber mixture into a press mold,
- d) closing of the press mold,
- e) applying pressure to the fiber mixture,
- f) solidifying the binding material, and
- g) opening of the press mold and removing the bipolar plate.
