Abstract: A method of activating a fuel cell includes: supplying a fuel to an anode of the fuel cell; supplying a gas mixture to a cathode of the fuel cell; applying a second load, which is equal to or less than a predetermined first load, to a stack of the fuel cell after supplying the gas mixture to the cathode; discontinuing the supply of the gas mixture; resupplying the gas mixture to the cathode when a voltage of the stack of the fuel cell is a predetermined voltage or less after discontinuing the supply of the gas mixture; and applying a third load, which is higher than the predetermined first load, to the stack of the fuel cell, where the supply of the fuel to the anode of the fuel cell is maintained.

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.
