長い時間が必要であった。However, since a large capacity storage battery is required to drive the display unit, it is used only for a small information display device, and the display time is as short as about 10 minutes. The storage batteries were rarely used, and the storage batteries were used only for compensating for power failures in control circuits and communication circuits. Also, once discharged, the storage battery required a long time to charge.

用することは不適切であった。Therefore, a fuel cell can be considered as an emergency power supply which can recover its function in a short time and whose operation time does not depend on the size of the battery. However, hydrogen used in current fuel cells is not a general-purpose fuel and is specified as a highly dangerous gas by the Industrial Safety and Health Law, and it uses natural gas and propane gas as fuel. In this case, it was inappropriate to adopt it as a steady state power supply.

It will be described together with the timing chart of FIG. When a power failure detection device (not shown) detects a power failure state of the commercial power supply in a state where road information and the like are displayed, first, the controller 10 switches the switch 9 so as to connect the storage battery 8 and the information display device 11. Therefore, the information display device 11 continues to display information by the storage battery 8.

水素ボンベ６からの水素を燃料電池本体５に供給する。On the other hand, the controller 10 opens the valve 2 and supplies propane gas or natural gas from the fuel tank 1 to the fuel reformer 3 when the power failure is detected. This fuel reformer 3 takes about 30 minutes to convert to hydrogen, during which time the controller 10 opens the valve 7 and
Hydrogen from the hydrogen cylinder 6 is supplied to the fuel cell main body 5.

However, the output of detecting the pressure of hydrogen at the time when the fuel reformer 3 generates hydrogen, or the valve 7 is closed after a certain period of time,
Further, the valve 4 is opened.

As described above, the fuel cell main body 5 generates power using the hydrogen from the hydrogen cylinder 6 in the time until the fuel reformer 3 generates hydrogen, that is, about 30 minutes. The purpose of a hydrogen cylinder filled with hydrogen designated as a gas can be achieved by using a small cylinder having a volume equivalent to that of a small fire extinguisher.
