Abstract
Disclosed are an electrode gas diffusion layer assembly (EGA) and a fuel cell stack including the same. The content of the binder in the electrode and the content of the binder in the adhesive layer that attaches the electrode to the gas diffusion layer (GDL) may be optimized. Thus, it is possible to reduce the occurrence of flooding and the deterioration in durability/performance caused by a dry atmosphere in the EGA including the electrode and the adhesive layer, so that the output density per unit area is improved while the trade-off is minimized.
