Title:
COOLING SYSTEM FOR FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2022/230575
Kind Code:
A1
Abstract:
A cooling system (20) for a fuel cell is provided with: a refrigerant flow channel (21) through which a refrigerant for cooling a fuel cell (10) circulates; a radiator (22) that dissipates heat from the refrigerant that has passed through the fuel cell; and a bypass channel (25) that flows the refrigerant so that the radiator is bypassed. The cooling system is provided with: a thermostat valve (26) that selects the flow path of the refrigerant between the radiator and the bypass channel according to the temperature of the refrigerant; and a refrigerant temperature sensor (27) that measures the temperature of the refrigerant that has passed through the fuel cell. The cooling system is provided with a control unit (28) that executes, when a temperature difference between a target temperature of the fuel cell and a detected temperature of the refrigerant temperature sensor is equal to or larger than a predetermined value, temperature adjustment processing for reducing the temperature difference by changing the temperature hysteresis characteristics of the thermostat valve.
