Claims15
A method for manufacturing a fuel cell separator, the method comprising:
- a first step of providing a raw material of a continuous carbon-fiber composite in a semi-cured state;
- a second step of forming the raw material to have the length and shape of the separator;
- a third step of stacking and adhering a single or a plurality of the raw materials cut according to the length of the separator;
- a fourth step of disposing the raw material, stacked in a single or multi-layer, on a high temperature hot press to be heated and pressed;
- a fifth step of removing unnecessary portions from the heated and pressed separator;
- and
- a sixth step of post-curing the thus obtained separator.
