description 본 발명은 한지에 탄소나노튜브를 담지시켜서 전기전도성을 향상시킬 수 있는 연료전지용 기체확산층의 제조방법 및 이에 의해 제조되는 기체확산층에 관한 것이다. 본 발명의 일 실시형태에 따른 연료전지용 기체확산층 제조방법은 연료전지의 단위 셀을 구성하는 기체확산층을 제조하는 방법으로서, 한지를 이용하여 담지체를 준비하는 담지체 준비단계와; 탄소물질을 용매에 분산시킨 분산액을 준비하는 분산액 준비단계와; 상기 담지체에 상기 분산액을 도포하는 도포단계와; 분산액이 도포된 담지체를 열처리하여 담지체에 탄소물질을 고정시키는 열처리단계를 포함한다. A method for manufacturing a gas diffusion layer for a fuel cell wherein carbon nanotubes are impregnated into Korean paper, thereby enhancing electroconductivity, and a gas diffusion layer manufactured thereby. The method for manufacturing a gas diffusion layer for a fuel cell which is to manufacture a gas diffusion layer as a constituent member of a unit cell in a fuel cell, includes a support preparation step of preparing a support with Korean paper; a dispersion preparation step of dispersing a carbon substance in a solvent to form a dispersion, a coating step of coating the support with the dispersion, and a thermal treatment step of thermally treating the dispersion-coated support to fix the carbon substance to the support.
