A fuel cell system (100a) includes a fuel cell (11), a fuel gas supplier (16) configured to supply a fuel gas; an oxidizing gas supplier (17) configured to supply an oxidizing gas, and a controller (20), and further includes a moisture supply mechanism (27, 28, 29) configured to supply moisture to at least one of an anode and a cathode of the fuel cell, wherein the controller is configured to control the moisture supply mechanism based on at least one of either a dew point of the fuel gas or information related to the dew point and either a dew point of the oxidizing gas or information related to the dew point as to increase at least either the dew point of the fuel gas or the dew point of the oxidizing gas, in order to supply moisture to at least one of the anode or the cathode of the fuel cell before cutting off electric connection between the fuel cell and a load, and is configured to thereafter cut off the electric connection between the fuel cell and the load.
