Abstract: A fuel cell system that has a fuel cell stack is provided. The system includes an electrolyte membrane, and a cathode and an anode that are a pair of electrodes disposed on opposite sides of the electrolyte membrane.

The fuel cell system reduces the concentration of hydrogen discharged to the outside of the vehicle by reducing the concentration of hydrogen in the cathode before driving of the fuel cell is initiated.
