<P>PROBLEM TO BE SOLVED: To reduce the ineffective remaining amount of a fuel cell. <P>SOLUTION: The fuel cell system comprises a fuel cell stack 1, a hydrogen tank 2 storing hydrogen gas, i.e. the fuel of the fuel cell stack 1, a hydrogen supply passage 3 through which hydrogen gas is supplied from the hydrogen tank 2 to the fuel cell stack 1, a pressure-reducing valve 5 provided on the hydrogen supply passage 3, a medium pressure device 8 arranged on the hydrogen supply passage 3 downstream of the pressure-reducing valve 5, and a check valve 6 arranged on the hydrogen supply passage 3 downstream of the pressure-reducing valve 5 and upstream of the medium pressure device 8. Cracking pressure of the check valve 6 is set at a predetermined pressure value associated with the lower limit pressure required for ensuring the sealability of the medium pressure device 8. <P>COPYRIGHT: (C)2013,JPO&INPIT |
