Abstract
The present invention provides a ventilation apparatus for a fuel cell box, reliably performs ventilation of the fuel cell box after shutting down the operation of the fuel cell (when ignition is off), comprising a fuel cell box 3 housing a fuel cell 2, an extractor fan 4 for performing a ventilation of the fuel cell box 3, an auxiliary battery 5 which can drive the extractor fan 4, a capacitor 7 which can drive the vehicle drive motor 6 and which can also drive extractor fan 4, a state detector 8 which detects the status of the auxiliary battery 5, and an ECU 9 connected to the state detector 8 to thereby determine the status of the auxiliary battery 5, wherein the capacitor 7 drives the extractor fan 4 under the control of the ECU 9.
Claims3
A ventilation apparatus for a fuel cell system comprising at least a fuel cell and a fuel cell box housing the fuel cell, the ventilation apparatus comprising:
- an extractor fan which performs ventilation of said fuel cell box;
- a storage battery, which drives the extractor fan to ventilate the interior of the fuel cell box for a predetermined time when power generation by the fuel cell is shut down;
- and
- an abnormality detection device which detects an abnormality of said storage battery;
- wherein said extractor fan is driven by a power supply which backs up the storage battery, based on said abnormality detection device, to ventilate the interior of the fuel cell box.
