A fuel cell system includes a fuel cell (1), an evaporating portion (2), a reforming portion (3), a tank (4), a heating portion (40), a water supply passage (8), a water supply source (80) being switchable between a normal mode in which water in the tank is sent to the evaporating portion by a first rotation, and a reverse mode in which the water in the water supply passage is returned to the tank by a second rotation, and a control portion (100) performing a freeze restraining process by controlling the water supply source to alternately operate in the normal mode and the reverse mode in a case where the control portion determines a possibility of a freezing or a start of the freezing of at least one of the water supply passage and the water supply source. |
