Beschreibung
Zusammenfassung:	PURPOSE: A producing method of a carbon nanotube/carbon composite gas diffusion layer for a fuel cell is provided to remarkably improve the fuel efficiency of the fuel cell. CONSTITUTION: A producing method of a carbon nanotube/carbon composite gas diffusion layer for a fuel cell comprises the following steps: forming a spin solution containing a polyacrylonitrile solution and a carbon nanotube; forming a carbon nanotube/poly acrylonitrile composite fiber by spinning the spin solution and solidifying the spin solution inside methanol; forming a carbon nanotube/carbon composite fiber by oxidizing and carbonizing the carbon nanotube/poly acrylonitrile composite fiber; forming a composite composition by mixing the carbon nanotube/carbon composite fiber with a poly acrylonitrile aqueous solution; drying the composite composition to form a web-shaped form; forming a precursor with the web-shaped form; and plasticizing the precursor.
