Patent abstract
A method of manufacturing a fuel cell bipolar plate that improves dimensional accuracy even with viscous material, eliminates the need for large-scale production equipment such as a press to make a pre-formed product, and furthermore, enables manufacturing time for the fuel cell bipolar plate to be reduced. Powdered raw material A containing electrically conductive material and resin is dropped into a filling container so that a top thereof is flat. The powdered raw material A inside the filling container is then heated to form a temporary cast B, the temporary cast B is set in a mold in which a predetermined pattern is formed, and heated and compressed to form a fuel cell bipolar plate.
