Carbon substrate for gas diffusion layer, gas diffusion layer using the same, and electrode for fuel cell, membrane-electrode assembly and fuel cell comprising the gas diffusion layer
A carbon substrate for a gas diffusion layer that has a porosity gradient in a thickness direction thereof, a gas diffusion using the carbon substrate, an electrode and a membrane-electrode assembly for a fuel cell that include the gas diffusion layer, and a fuel cell including the membrane-electrode assembly having the gas diffusion layer are provided. The gas diffusion layer has improved water discharge ability and improved bending strength both in the machine direction and cross-machine direction.
