Abstract
A gas diffusion layer for a fuel battery is used, which is configured by a porous member containing conductive particles, conductive fibers and a polymer resin as main components. An aggregate of the conductive fibers is formed inside the porous member, and an area ratio of the aggregate in any cross-section of the porous member is 0.5% or more and 8% or less. Further, a membrane electrode assembly including the gas diffusion layer for the fuel battery is used. Further, a fuel battery including the gas diffusion layer for the fuel battery is used.
