MANUFACTURING METHOD OF CNT BULKY PAPER, CNT BULKY PAPER USING IT AND BIPOLAR PLATES FOR THE FUEL CELL

摘要

PURPOSE: A method for manufacturing CNT bulky paper is provided to lower manufacturing costs by minimizing the used amount of expensive carbon nanotube and to prepare a CNT bulky paper layer with excellent electric conductivity. CONSTITUTION: A method for manufacturing CNT bulky paper comprises the steps of: (a) dispersing hydrophilic carbon nanotube in distilled water to obtain dispersion; (b) obtaining slurry by uniformly mixing nafion in the dispersion; and (c) obtaining a carbon nanotube bulky paper using the slurry. The dispersion concentration of hydrophilic carbon nanotube based on distilled water is 0.1~10 %.
