Abstract
A fuel cell cooling system mounted on a vehicle includes a flow path for a coolant; a cooling unit that cools the coolant in a cooling unit flow path; a fuel cell to be cooled through heat exchange with the coolant in a fuel cell flow path; a heat generating body to be cooled through heat exchange with the coolant in a heat generating body flow path; first and second pumps that pump the coolant in the fuel cell and heat generating body flow paths, respectively; and a control circuit. When the vehicle is started, the control circuit performs a first process of actuating the first pump with the second pump stopped, and a second process of actuating the first and second pumps when the temperature of the coolant in the fuel cell or cooling unit flow path exceeds a first reference value during the first process.
