FUEL SUPPLY DEVICE INTEGRATION STRUCTURE

PROBLEM TO BE SOLVED: To provide a fuel supply device integration structure that can be made small in size. SOLUTION: In the fuel supply device integration structure of a fuel cell system, a hydrogen gas is supplied to a fuel cell through a humidifier 18 provided in a hydrogen gas supply path 5 and a hydrogen offgas exhausted from the fuel cell joins the hydrogen gas supply path 5 through an ejector 11 and forms a hydrogen offgas circulation path 8. The ejector 11 is fitted at the nearly center of an inlet block 21 constituting the entrance side of the humidifier 18, and instruments participating in the supply and exhaust of the fuel of the fuel cell are arranged at a position straddling over the ejector 11 and connected and fixed to the inlet block 21.
