Title:
FUEL CELL COOLING SYSTEM
Document Type and Number:
Japanese Patent JP2021190168
Kind Code:
A
Abstract:
To provide a fuel cell cooling system capable of exhausting air in a case where air is mixed into a coolant passage connected from an upper side in a gravity direction to a confluent part.SOLUTION: A fuel cell cooling system 1000 comprises at least: a radiator passage 104 in which a liquid-state coolant for cooling a fuel cell 120 flows; an ion exchanger passage 106 which is branched from the radiator passage 104 in a branch part and confluent with the radiator passage 104 in a confluent part 107; a three-way valve 160 which controls flow rates of the coolant to flow to the radiator passage 104 and the ion exchanger passage 106; a control unit 300 which controls an opening degree of the three-way valve 160; and a detection unit 400 capable of detecting that a gas is mixed into the coolant. The radiator passage 104 is a passage connected from an upper side in a gravity direction to the confluent part 107. In a case where it is detected by the detection unit 400 that a gas is mixed into the coolant, the control unit 300 controls the opening degree of the three-way valve 160 in such a manner that the flow rate of the coolant to flow into the radiator passage 104 becomes more than the flow rate of the coolant to flow into the ion exchanger passage 106.SELECTED DRAWING: Figure 1
