A fuel cell system (100) is disclosed, which has a fuel gas generator (3) configured to be supplied with raw fuel, water and fuel for combustion to generate fuel gas by utilizing the combustion heat of the fuel for combustion; a fuel cell (1) configured such that the fuel gas is supplied to fuel gas routes (b1, 1a, c1) and oxidizing gas is supplied, thereby generating electric power; heating medium routes (b2, 1d, c2) configured such that the fuel gas is supplied thereto instead of being supplied to the fuel gas routes; a route switching device (4) configured to switch the destination of the fuel gas between the fuel gas routes and the heating medium routes; and a controller (8). The controller controls the route switching device such that, during warming-up of the fuel gas generator, the fuel gas is supplied to the heating medium routes and then used as the fuel for combustion and such that, after the warming-up, the fuel gas is supplied to the fuel gas routes instead of being supplied to the heating medium routes and then used as the fuel for combustion.
