FUEL CELL SYSTEM

摘要

A fuel cell system (1) includes: a fuel cell (2) configured to perform an external power feeding; a coolant circulation passage (17) through which a coolant cooling the fuel cell circulates; a radiator (18) mounted on the coolant circulation passage; a water pump (23) configured to circulate a coolant in the coolant circulation passage; a flow dividing valve (19) configured to control a flow rate of the coolant flowing through the radiator; a fan (18a) configured to send an air to the radiator; and a controller (21) configured to, when a first prescribed period elapses in a state where a temperature of the coolant is equal to or more than a first prescribed temperature and an opening degree of the flow dividing valve makes the flow rate of the coolant flowing into the radiator equal to or more than a prescribed flow rate, give a priority to the rise in a driving voltage of the fan over the increase in the flow rate by the water pump, and when a second prescribed period elapses in a state where the temperature of the coolant is equal to or more than a second prescribed temperature after the driving voltage of the fan is raised, increase the flow rate by the water pump.
