    摘要： There is provided an anomaly judgment device that is capable of detecting an abnormal state of a system highly accurately and obtaining an accurate result. The anomaly judgment device may include a plurality of anomaly judgment devices for judging an anomaly of the system and, in cases where it is judged by the plurality of anomaly judgment devices that there is an anomaly, a judgment device judges that a system anomaly exists. Hence, even in the event of a localized abnormal state judgment by one anomaly judgment device or failure, a final judgment is not made based on that anomaly alone, and at least one other anomaly judgment is made, whereby erroneous judgments can be eliminated and a highly accurate anomaly judgment is possible.

    摘要： A fuel cell system capable of reliably and rapidly discharging liquid in a fuel cell stack to the outside is provided. In a fuel cell system having a discharge path (76) that allows discharge of at least liquid in a fuel cell stack (20), at the time of actuation of the fuel cell stack (20), reaction gas is supplied to the fuel cell stack (20) at a higher speed or in a greater amount than during normal operation of the fuel cell stack (20). By supplying the reaction gas at a high speed or in a great amount before actuation, residual liquid in the fuel cell stack (20) can be blown off and thus reliably and rapidly discharged to the outside. The residual liquid can be discharged more easily when a volume (30) is provided in the discharge path (76) or the pressure inside the fuel cell stack (20) is set to a negative level at the time of actuation thereof.

    摘要： A fuel cell system according to the present invention is characterized by comprising a fuel cell, measurement means for measuring impedances of the fuel cell in two kinds or more of frequency regions, and first judgment means for judging two or more parameters concerned with an internal state of the fuel cell based on measurement results of the impedances in the respective frequency regions. According to such a constitution, the impedances in the two or more types of frequency regions (a high frequency region, a low frequency region and the like) are measured to judge two or more parameters such as a wet state of an electrolytic film of the fuel cell and a supply state of a fuel gas, which are concerned with the internal state of the fuel cell based on this measurement result. Since such judgment is performed, as compared with the conventional technology, the internal state of the fuel cell can accurately be grasped, and highly efficient and highly robust control of the fuel cell system can be performed.
