    摘要： The theme of the present invention is a fuel cell system capable of avoiding a disadvantage caused by the maintaining of a low-efficiency operation to improve the safety of a system operation. The fuel cell system is configured to perform the low-efficiency operation having a large power loss as compared with a usual operation at a predetermined low temperature to raise the temperature of a fuel cell in a short time as compared with the usual operation. The fuel cell system prohibits the low-efficiency operation to execute the usual operation, in a case where predetermined conditions are established at the predetermined low temperature. The predetermined conditions include a time when the generated power of the fuel cell cannot be consumed, a time when this generated power cannot be accumulated in a battery, or a time when the flooding of the fuel cell is generated.

    摘要： In a fuel cell system comprising a fuel cell with plural cells and performing processing for limiting a supply current to a load by performing a compensation computation with respect to a system-request current corresponding to a system-request power requested by the system based on the lowest cell voltage in the cells, the compensation computation being performed for limiting the supply current through a PI compensation using, as a reference value, a current value of the system-request current as of the time when the lowest cell voltage falls below a predetermined lowest-cell-voltage acceptable value, values for gains in the PI compensation for limiting the supply current are different from values for gains in the PI compensation for restoring the supply current. The system-request current can be securely limited in any operation statuses, and in addition, the supply current can be made rapidly responsive during the limitation of the current, while the supply current can be stably converged during the current restoration.

    摘要： Output voltage of a fuel cell 2 is decreased by a converter 51 to conduct an activation treatment to catalyst of the fuel cell 2, while measuring reduction current by a current sensor 2a while scanning output voltage of the fuel cell 2 over a certain range by the converter 51 as measurement of cyclic voltammetry under the condition that supply of oxidation gas to the fuel cell 2 is stopped from a compressor 31, and this measurement value is integrated by a control device 6. The control device 6 finds a charge amount of electrode catalyst of the fuel cell 2 based on this integration value, decides whether this charge amount is smaller or not than a degradation decision value, and displays this decision result on a display 55. A decision can be made precisely as to whether the electrode catalyst of the fuel cell is degraded or not.
