Abstract: A fuel gas supplying apparatus for a fuel cell system includes an exhaust apparatus having an exhaust pipe; a fuel apparatus for supplying fuel to the fuel cell; a regulator arranged to reduce pressure of the fuel gas provided to the fuel cell; and a fuel gas emitting pipe confluence-connected to the exhaust pipe, to emit fuel gas to an outside of the fuel apparatus by using the exhaust pipe as a pipe for temporarily emitting gas to the atmosphere. The regulator includes a plurality of pressure relief valves, a pressure reducing portion, and a solenoid valve upstream of the pressure reducing portion. The pressure relief valves are connected upstream and downstream of the pressure reducing portion.
