摘要： Provided is a fuel cell system capable of achieving both of improving purge efficiency and preventing deterioration of the fuel cell, and a control method of the fuel cell system. The fuel cell system includes a circulation rate adjusting unit that adjusts a circulation rate of a circulation gas, a first startup purge unit that performs the first startup purge by opening a purge valve in a state where the circulation rate of the circulation gas is increased to be a mixing promotion rate capable of promoting mixing of the fuel gas with the circulation gas at system startup of the fuel cell system, and a second startup purge unit that performs the second startup purge by opening the purge valve in a state where the gas circulation rate is reduced to be less than the mixing promotion rate after the first startup purge.

摘要： In a method of operating a fuel cell, a voltage difference between voltages of a first unit cell and a second unit cell is detected. Whether the voltage difference is out of a predetermined range is determined. If the voltage difference is determined to be out of the predetermined range, humidity of a first reactant gas before being supplied to a first reactant gas passage is adjusted or humidity of a second reactant gas before being supplied to a second reactant gas passage is adjusted. The first reactant gas passage is provided in a first separator. The first reactant gas is to be supplied to one of first electrodes through the first reactant gas passage. The second reactant gas is to be supplied to another of the first electrodes through the second reactant gas passage.

摘要： A method for controlling a fuel cell system including a fuel cell which includes an anode electrode and a cathode electrode sandwiching a solid polymer electrolyte membrane therebetween, includes driving a pump to supply an oxidant gas to the cathode electrode. The pump has a minimum supply amount of the oxidant gas. A fuel gas is supplied to the anode electrode to generate electric power via an electrochemical reaction between the fuel gas and the oxidant gas. It is determined whether a target amount of the oxidant gas to be supplied to the cathode electrode is lower than the minimum supply amount. An opening degree of a pressure adjusting valve is adjusted to adjust an amount of the oxidant gas supplied to the cathode electrode to be the target amount when the target amount is determined to be lower than the minimum supply amount.
