| 摘要 |
This fuel cell system comprises a fuel cell stack (10), a radiator (51), a cooling water supply passage (53f), a cooling water discharge passage (53d), a bypass cooling water passage (53b), a deionizer (55), a stack side cooling water pump (56s), a radiator side cooling water pump (56r), and a bypass cooling water control valve (57). The radiator side cooling water pump and the bypass cooling water control valve are each controlled so as to cause the selective execution of either a stack flow-through mode in which the cooling water flows at least inside the fuel cell stack, or a stack bypass mode in which the cooling water circulates inside the radiator and inside the bypass cooling water passage almost without flowing inside the fuel cell stack. |
