Abstract
A fuel cell system of the present disclosure performs a first and a second catalyst activation process, and the first catalyst activation process is performed where a flow rate of the air supplied to the fuel cell by the air compressor is reduced to be less than that before the refresh control is performed while keeping an amount of a current drawn from the fuel cell by the fuel cell converter at the same value as that before the refresh control is performed, and the second catalyst activation process is performed where the value of the current drawn from the fuel cell by the fuel cell converter is increased to be greater than that before the refresh control is performed while keeping the flow rate of the air supplied to the fuel cell by the air compressor at the same value as that before the refresh control is performed.
