Abstract
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.
