摘要：
PURPOSE: A fuel cell with enhanced mass transport capability is provided to use a hydrophilic gas diffusion layer and to easily discharge water generated from electrochemical reaction, thereby improving cell performance. CONSTITUTION: A fuel cell with enhanced mass transport capability consists of a polymer electrolyte membrane-electrode assembly, gas diffusion layer which is a porous body, and a unit cell in which a separator with reaction gas paths are laminated. The gas diffusion layer has a structure that pores with nanometer scale protrusions or pores are formed on the surface of the porous body with micron scale roughness and a hydrophobic thin film is formed on the surface.
