CARBONACEOUS MATERIAL AND DISPERSION CONTAINING THE SAME

摘要

A water-repellent carbonaceous material obtained by contacting a carbonaceous material with a water-repellent substance in a molten state or dropping an organic-solvent solution of a water-repellent substance into an aqueous dispersion of a carbonaceous material; and a gas diffusion layer, catalyst layer, or separator for electrodes for fuel cells which each comprises the water-repellent carbonaceous material.
