Abstract: A fuel cell stack includes a plurality of unit cells, a cooling plate and a block plate. Each unit cell includes a cathode electrode and an anode electrode respectively at opposing sides of an electrolyte membrane, and a separator facing each of the cathode electrode and the anode electrode. The cooling plate is between adjacent unit cells a cooling medium flows in the cooling plate. The block plate is between the cooling plate and an adjacent unit cell of the adjacent unit cells. The block plate blocks the cooling medium flowing in the cooling plate from contacting the adjacent unit cell of the adjacent unit cells.
