A fuel cell system includes: a fuel cell having laminated cells; a measuring unit that measures an impedance of the cell and a purging unit that performs purging to discharge residual water from a gas passage. The cell includes a wet region and a dry region which are set depending on a distribution of water in the cell when the purging is executed so as to set a total amount of water in the fuel cell to be a necessary amount of water to start up the fuel cell; the measuring unit measures the impedance at a local portion located at a boundary portion between the wet region and the dry region in the cell; and the purging unit terminates the purging when the impedance measured by the measuring means is larger than a predetermined reference threshold value.
