| description | The present disclosure relates to a fuel cell stack having a cathode-side separator and an anode-side separator which are made of different materials to prevent performance degradation of stacks and corrosion and damage of components. A fuel cell stack according to exemplary embodiments of the present disclosure may have multiple unit cells stacked therein, in which each unit cell of the multiple unit cells may include: a membrane electrode assembly (MEA); a pair of gas diffusion layers (GDLs) disposed on opposite surfaces of the MEA; and an anode-side separator and a cathode-side separator disposed to face each other, the MEA and the pair of GDLs being disposed therebetween, in which the cathode-side separator has a corrosion resistance higher than a corrosion resistance of the anode-side separator. |
