    摘要： A fuel cell system and a control method therefor are provided. The fuel cell system includes: a fuel cell formed of a plurality of stacked power generating elements; a cell voltage measuring unit detecting negative voltage in any one of the power generating elements; a control unit controlling electric power output from the fuel cell; and an accumulated current value measuring unit measuring an accumulated current value obtained by time integration of current output from the fuel cell. The control unit prestores a correlation between accumulated current values and current densities that are allowable for the fuel cell in a period during which negative voltage is generated. When negative voltage has been detected, the control unit executes output restricting process of restricting electric power output from the fuel cell so as to fall within an operation allowable range defined by the accumulated current values and current densities of the correlation.

    摘要： An IR resistance of each of unit cells is measured, and a highest unit cell voltage as a threshold voltage is set based on the IR resistance and load current. The setting of the highest unit cell voltage uses map data that approximates current-voltage characteristics of a unit cell when the fuel gas is insufficiently supplied. In that case, the highest unit cell voltage is determined based on the voltage with respect to the load current obtained from the map data, and the IR loss calculated from the IR resistance and the load current. This highest unit cell voltage is compared with the measured unit cell voltage. If the unit cell voltage is below the highest unit cell voltage, the power generation of the fuel cell is stopped or restrained.
