ン１８を運転させるものである。 A battery chamber 13 is provided on the lower side of the engine chamber 3 with a partition plate 12 interposed therebetween. This battery chamber 13 has a battery 1 that serves as a power source for a starter motor (not shown) built into the engine 1.
4 is accommodated, and a ventilation inlet 15 and a ventilation outlet 16 are provided. Further, the battery chamber 13 is provided with a fan 18 whose power source is the battery 14 and whose operation is controlled by the temperature control device 17. This temperature control device 17 has a temperature sensor 19 that detects the room temperature of the battery chamber 13,
The fan 18 is operated when the room temperature is higher than a set temperature (for example, 40° C.).

きる。 According to this embodiment, since the battery chamber 13 that accommodates the battery 14 is provided on the side of the engine compartment 3 and partitioned by the partition plate 12, the hydrogen gas released from the battery 14 is transferred to the battery chamber 13.
Collects at the top of 3. Furthermore, since the battery chamber 13 is provided with a ventilation inlet 15 and a ventilation outlet 16, the hydrogen gas in the battery chamber 13 is removed from the ventilation inlet 15.
It is discharged to the outside from the ventilation outlet 16 together with the air flowing in from the ventilation outlet 16. Therefore, a ventilation port is not required in the engine compartment 3, and the engine compartment 3 can be sufficiently sealed to prevent engine noise from leaking to the outside.
また、夏期のように外気温が高く、バツテリー
１４から水素ガスが多量に放出される場合でも、
バツテリー室１３の室温が設定温度以上になる

発する心配がない。 Furthermore, even when the outside temperature is high and a large amount of hydrogen gas is released from the battery 14, such as in the summer,
When the room temperature of the battery chamber 13 becomes higher than the set temperature, the fan 18 is operated to forcibly ventilate the battery chamber 13, so there is no fear that the battery chamber 13 will be filled with hydrogen gas and explode.
なお、エンジン室３を十分に密閉すると、エン
ジン１からの放熱によりエンジン室３の温度が上

熱交換器を組込むと良い。 Note that if the engine compartment 3 is sufficiently sealed, the temperature of the engine compartment 3 will rise due to heat radiation from the engine 1, so it is preferable to incorporate a heat exchanger for cooling the engine compartment into the refrigeration cycle.
