Abstract
Provided is a gas diffusion layer for a fuel cell, wherein a reactive gas passage groove for distributing a reactive gas is formed in one principal surface of the gas diffusion layer, and a reinforcing member is provided along the reactive gas passage grooves. Thus, the deformation of the gas diffusion layer due to a fastening pressure can be suppressed to improve the power generation performance.
