FUEL CELL SYSTEM

摘要

A fuel cell system includes a control unit configured to perform air-conditioning-system preparation control, wherein, under the air-conditioning-system preparation control, when an air conditioning system is not requested to heat air, it is determined whether or not a coolant within a coolant circulation passage is capable of being supplied to an air conditioning circuit, when the coolant within the coolant circulation passage is not capable of being supplied to the air conditioning circuit, the heater is operated to maintain a first predetermined temperature or higher of the coolant within the air conditioning circuit, and When the coolant within the coolant circulation passage is capable of being supplied to the air conditioning circuit, the air-conditioning water pump is operated to draw the coolant from the coolant circulation passage into the air conditioning circuit and to maintain the first predetermined temperature or higher of the coolant within the air conditioning circuit.

主权项

1. A fuel cell system comprising:
a fuel cell stack; a coolant circulation passage through which a coolant for cooling the fuel cell stack circulates; an air conditioning system including an air conditioning circuit that is connected to the coolant circulation passage and shares the coolant circulating through the coolant circulation passage; an air-conditioning water pump causing the coolant to flow through the air conditioning circuit; a heater arranged on the air conditioning circuit; and a control unit configured to perform air-conditioning-system preparation control, wherein, under the air-conditioning-system preparation control, when the air conditioning system is not requested to heat air, it is determined whether or not the coolant within the coolant circulation passage is capable of being supplied to the air conditioning circuit, when the coolant within the coolant circulation passage is not capable of being supplied to the air conditioning circuit, the heater is operated to maintain a temperature of the coolant within the air conditioning circuit at a first predetermined temperature or higher, and when the coolant within the coolant circulation passage is capable of being supplied to the air conditioning circuit, the air-conditioning water pump is operated to draw the coolant from the coolant circulation passage into the air conditioning circuit and to maintain the temperature of the coolant within the air conditioning circuit at the first predetermined temperature or higher.
