description The present invention provides a fuel cell microporous layer coating solution formed by dispersing an intermediate mixture of a solvent, carbon powder, a dispersant, and a foaming agent, and stirring a polytetrafluoroethylene dispersion solution in a dispersed intermediate mixture. The present invention controls the pore size of the microporous layer to suppress an increase in electrical resistance through a gas diffusion layer and to improve gas permeability. 본 발명은 용제, 탄소분말, 분산제 및 발포제가 혼합된 중간 혼합물을 분산시키고, 분산된 중간 혼합물에 폴리테트라플루오르에틸렌 분산액을 교반하여 형성되는 연료전지 미세기공층 코팅액을 제공한다.
