<P>PROBLEM TO BE SOLVED: To suppress increase in complication of a fuel cell control system, by controlling the opening/closing of a communicating passage by the control of nozzle opening area. <P>SOLUTION: An ejector 340 is equipped with a supply port 530 supplying reaction raw gas, a suction port 508 sucking reaction exhaust gas exhausted from the fuel cell, and an outlet port 506 supplying reaction gas where the reaction raw gas and the reaction exhaust gas are mixed to the fuel cell. A nozzle 522 ejecting the reaction raw gas to the outlet port 506 side and the communicating passage 528 communicating the supply port 530 with the outlet port 506 not going via the nozzle 522 are installed in the ejector 340. A passage-opening/closing part 620 for opening/closing the communicating passage 508 changes from a closing state to an opening state, according to the movement of a needle 600 varying the opening area of the nozzle 522 in the farther opening direction than a position, at which the opening area of the nozzle 522 becomes in the prescribed opening area. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
