    摘要： A check valve is disposed in a hydrogen offgas circulation path which is connected to a fuel cell so as to flow the hydrogen offgas only in one direction. Inside a valve housing, a first compression chamber and a second compression chamber are provided such that a bulkhead is disposed therebetween. In the bulkhead 14, a first communication hole 18 and a second communication hole 19 are formed so as to communicate between the first compression chamber and the second compression chamber. In a first reed valve, an opening end is disposed upward and a fixed end is disposed downward. In a second reed valve, an opening end is disposed downward and a fixed end is disposed upward. By doing this, operability in the check valve after water has frozen can be improved.

    摘要： The ejector includes a diffuser, a nozzle, a needle, and a drive section. A throat portion and an increasing diameter portion are formed in a third conduit of the diffuser, and the nozzle and the needle are arranged coaxially with the third conduit. A first taper section of the needle is inserted into an aperture portion of the nozzle, and a second taper section is housed in the increasing diameter portion. A gap between the aperture portion and the first taper section constitutes a first fluid conduit, and a gap between the increasing diameter portion and the second taper section constitutes a second fluid conduit. The needle is provided so as to be shiftable in its axial direction by the drive section, and, by shifting the needle in its axial direction, it is possible to change both the first fluid conduit and the second fluid conduit simultaneously.

    摘要： An apparatus for dilution of discharged fuel of a fuel cell is provided, which has an inlet for guiding purged hydrogen gas coming from the fuel cell, a reservoir for storing the purged hydrogen gas guided through the inlet, and a cathode exhaust gas pipe penetrating the reservoir. The cathode exhaust gas pipe has a feature that it has holes inside the reservoir and is supplied with cathode exhaust gas of the fuel cell. Also the apparatus has a feature that the cathode exhaust gas pipe sucks the purged hydrogen gas stored in the reservoir through the holes and discharges the purged hydrogen gas diluted by mixing with the cathode exhaust gas.
