Abstract
A fuel cell system of the present invention includes a fuel cell (3); a water passage (8, 10, 12, 15, 17, 18); an electric heater (19) configured to heat the water passage; a water-related temperature detector (20); a first abnormality detector (22, etc.) configured to detect first abnormalities; a second abnormality detector (28, etc.) configured to detect second abnormalities; and a controller (21), and the controller is configured to stop an operation of the fuel cell system when the first abnormality is detected by the first abnormality detector or when the second abnormality is detected by the second abnormality detector. In a case where the fuel cell system stops since the second abnormality is detected by the second abnormality detector, the controller causes the electric heater (19) to carry out an operation as an antifreezing operation when the water-related temperature detector detects a temperature that is not more than a predetermined threshold. In a case where the fuel cell system stops since the first abnormality is detected by the first abnormality detector, the controller does not cause the electric heater (19) to carry out the operation as the antifreezing operatio…
