Fuel cell system and freezing prevention method thereof |
摘要 |
In a fuel cell system, a temperature sensor detects an internal temperature of a fuel cell. A cooling water pump is controlled so that it is stopped when the internal temperature of the fuel cell is equal to or lower than 0 degrees. A driving amount of the cooling water pump increases according to a rise in internal temperature of the fuel cell when the internal temperature is higher than 0 degrees. A degree of increase in driving amount is restrained when the internal temperature of the fuel cell is between 0 degrees and a predetermined temperature higher than 0 degrees.
