摘要： PROBLEM TO BE SOLVED: To reduce fuel consumption in a fuel cell while improving startability of a secondary battery. SOLUTION: A second circulation passage 42 to reach a battery case 41 is provided in the middle of a first circulation passage 31 as a cooling water system in a fuel cell stack FC. To the battery case 41, water can be supplied inward, and it is covered with heat insulation material. As an ignition switch is changed into an off-condition, operation of the fuel cell stack FC is stopped, and the second circulation passage 42 is then opened, so cooling water in the fuel cell stack FC is circulated to the battery case 41. After this, when a temperature T around a battery BT gets to a high temperature of a prescribed temperature TO or more, a cooling water pump 35 is stopped, and the second circulation passage 43 is closed, so cooling water is stored in the battery case 41. As a result, the battery BT can be continuously heated even after the ignition switch is put off.
