Abstract
A fuel cell system () of the present invention comprises a fuel cell (); a water circulating path () through which water associated with an operation of the fuel cell () circulates; a water circulator () for circulating water in the water circulating path (); a heater () for heating the water circulating path (); a first abnormality detector () for detecting a first abnormality which is an abnormality relating to leakage of water from the water circulating path (); and a controller (); the fuel cell system being configured to cause the water circulator () to perform a water circulating operation for circulating the water in the water circulating path () and cause the heater () to perform a heating operation for heating the water circulating path (), to suppress freezing in the water circulating path, wherein the controller () is configured to inhibit the water circulating operation for suppressing freezing and not to inhibit the heating operation for suppressing freezing, in a case where the fuel cell system () is shut down in response to detection of the first abnormality by the first abnormality detector ().
