摘要： At a start of a fuel cell, discharge of a generated water is ended at a proper timing. Supply of the reactive gas is started at a first flowrate. Then, in a case that the generated water retained by a reactive electrode is determined to outflow to an internal gas flow channel side among unit cells more than or equal to a preset determination cell number, the flowrate of the reactive gas is changed to a second flowrate that is smaller than the first flowrate.

摘要： A fuel cell system including a plurality of single-cell units, each of which include an electrolyte membrane disposed between an anode and a cathode and which generate electric power by a reaction of a fuel gas in the anode and an oxidizer gas in the cathode, and a fuel cell in-which the plurality of single-cell units are stacked. A plurality of voltage measurement devices measure the voltages of the single-cell units, respectively. A control unit determines the humidification state of the fuel cell based on the voltage of a second single-cell unit wherein when the voltage of the second single-cell is equal to or lower than an insufficient-humidification-determining voltage which is higher than the predetermined voltage the control unit determines that humidification of the fuel cell is insufficient, disposed in the vicinity of a first single-cell unit, the first single-cell unit having a voltage that is equal to or lower than a predetermined voltage.
