The present invention relates to a fuel cell stack and, more particularly, to a fuel cell stack in which an additional supporting body is inserted between a separation plate and a gas diffusion layer so that the cell performance and durability of the stack can be improved. The supporting body, which has multiple supporting lines, is inserted between the separation plate and the gas diffusion layer so that the multiple supporting lines are arranged in a direction perpendicular to a channel flow path. Accordingly, the amount of pressing on the gas diffusion layer by a land portion of the separation plate can be reduced and the height of the channel flow path can be increased, and thus fuel supply to an electrode film bonded body and a water discharge performance can be improved. Ultimately, the cell performance and durability of the stack can be improved. |
