PEM FUEL CELL BIPOLAR PLATE COMPRISING COMPOSITE LAYER COMPRISING CNTS GROWN ON THE CARBON FIBER AND METHOD FOR FABRICATING THE SAME

摘要

PURPOSE: A composite for fuel cell separator is provided to obtain dispersity of carbon nanotubes, and to improve electricity by the carbon nanotubes, and to improve mechanical properties because of carbon fiber. CONSTITUTION: A composite for fuel cell separator comprises a conductive additive, additives, and polymer. The conductive additive is a carbon fiber(1) grown on carbon nanotubes(3). The diameter of the carbon fiber is 5-10 micron. The diameter of the carbon nanotube grown on the carbon fiber is 10-100 nm and a length is 5-300 micron.
