A fuel cell includes a cell stack configured such that a plurality of unit cells is stacked, an end plate disposed at one of two ends of the cell stack, the end plate including an air inlet, an air outlet, and a groove portion including a first groove adjacent to and spaced apart from the air outlet and a second groove connecting the first groove to the air inlet, and a cover configured to cover a region of the end plate in which the air inlet, the groove portion and the air outlet are formed so as to form a flow path together with the second groove to allow air to pass therethrough. The cover includes a first through-hole communicating with the first groove, a second through-hole communicating with the air outlet, and a partition wall isolating the first and second through-holes from each other.
