Abstract
Gas diffusion layers, that is, an anode-side gas diffusion layer and a cathode-side gas diffusion layer that are attached to an MEA have irregularities on fiber surfaces of carbon fibers deposited in a layer thickness direction. These irregularities on the fiber surfaces are formed when the fibers are extruded from an extrusion nozzle to be spun.
