    摘要： A control method for fuel cell system capable of executing an idle stop operation is provided, in which operation power generation of a fuel cell is selectively stopped according to a required output of a load and cathode gas is intermittently supplied to the fuel cell during an operation stop. An upper limit value and a lower limit value of an output voltage of the fuel cell during the idle stop operation is set, the cathode gas is intermittently supplied with the output voltage of the fuel cell set at a value between the upper limit value and the lower limit value, a wet/dry state of the fuel cell is detected, a wet/dry appropriate range in which the wet/dry state of the fuel cell during the idle stop operation is appropriate is set, and it is determined whether or not the detected wet/dry state of the fuel cell is within the set wet/dry appropriate range. If the wet/dry state of the fuel cell is determined to be outside the set wet/dry appropriate range, the output voltage of the fuel cell is reset, and the cathode gas is intermittently supplied with the output voltage of the fuel cell set at a value between the upper limit value and lower limit value of the reset output voltage.

    摘要： A fuel cell system includes a plurality of fuel cell stacks (1) and a plurality of power controllers (2). In the fuel cell system, the number of the fuel cell stacks (1) in operation and the number of the power controllers (2) in operation are varied as a function of a load, only one of the plurality of power controllers (2) is set as a master power controller (2), and the other one or more power controllers (2) are each set as a slave power controller (2). The master power controller (2) is capable of grid-independent operation during power grid failure. (i) The master power controller (2) is set so that the operating time of the one or more fuel cell stacks (1) connected to the one or more slave power controllers (2) is longer than the operating time of the fuel cell stack (1) connected to the master power controller (2), or (ii) when the voltage of the fuel cell stack (1) connected to the power controller (2) acting as the master power controller (2) is below a predetermined value, another power controller (2) is newly set as the master power controller (2).
