A fuel cell system includes: a fuel cell activation portion that starts electricity generation of a fuel cell; a cooling medium passage that is provided with a pump and that is provided for passing a cooling medium through a cell-side passage for the cooling medium; and a pump control portion that stops the pump for a first predetermined period after a start of the electricity generation caused by the fuel cell activation portion at a time when a temperature of the fuel cell is a low temperature lower than or equal to a predetermined value, and that starts operating the pump after the first predetermined period elapses. The pump control portion includes a cooling medium reverse portion that alternately reverses a direction of flow of the cooling medium in the cell-side passage according to elapsed time by controlling operation of the pump after the first predetermined period elapses.
