Abstract
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.
