    摘要: A humidification control method includes the steps of detecting a direct current resistance component by measuring impedance during power generation of a fuel cell stack, calculating a reaction resistance component based on the detected direct current resistance component and a stack voltage, detecting a humidified state of the fuel cell stack based on the detected direct current resistance component and the calculated reaction resistance component, and adjusting a quantity of humidification of a reaction gas supplied to the fuel cell stack based on the detected humidified state of the fuel cell stack.

    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.
