A fuel cell system comprising a fuel cell for generating power by receiving reaction gas supply and discharging reaction off gas, a gas passage for conducting reaction gas or reaction off gas, a valve unit arranged on the gas passage, and a controller for controlling the opening of the valve unit, wherein pressure downstream the valve unit is acquired (step S3) at the time of starting the fuel cell system, and when the downstream pressure is below a pressurization completion pressure (step S5: " YES"), the valve unit is subjected to duty control at a predetermined duty ratio (step S7, step S9). Consequently, generation of strange noise due to quick pressurization or generation of stress in a mechanical component is suppressed. |
