Abstract
Provided is a gas diffusion layer, in which a microporous layer has an inner wall of through passages and a region adjacent to the through passages containing a greater amount of a water-repellent binder resin than a region not adjacent to the through passages, and thus water formed by an electrochemical reaction is effectively discharged from the gas diffusion layer. When the gas diffusion layer of the present invention is used, an optimal water management may be possible for smooth operation under all humidity conditions including a high humidity condition and a low humidity condition, and thus a fuel cell having improved cell performance may be obtained.
