GAS DIFFUSION LAYER FOR FUEL CELL, FUEL CELL, AND METHOD OF MANUFACTURING GAS DIFFUSION LAYER FOR FUEL CELL

摘要

Gas diffusion layers, that is, an anode-side gas diffusion layer (23) and a cathode-side gas diffusion layer (24) 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.
