PROBLEM TO BE SOLVED: To provide a solid polymer fuel cell capable of preventing a catalyst and a catalyst carrier from being damaged by preventing a rise of the open circuit voltage when no-load or a light-load is applied.SOLUTION: This fuel cell stack formed by piling a plurality of fuel cells 4 through a separator 1 includes: an external circuit 8 formed by connecting terminals 7 provided in the outer periphery of each separator 1 to each other outside of the fuel cells 4; discharge resistors 6 which give a load onto the external circuit 8; and Zener diodes 5 which make the current on the external circuit 8 flow in the only one direction. |
