PURPOSE:To eliminate the wasteful consumption of a substituting inert gas and reduction in the pressure of an operating gas so as to restart a fuel cell power generating device by arranging an auxiliary inert gas cylinder in the device so as to derive the supply of gas to the device from the cylinder when electromagnetic valve operating power is lost. CONSTITUTION:A small-sized auxiliary inert gas cylinder 26 is arranged in a fuel power generating device, and then electromagnetic valves 24, 25 are arranged at the outlet of the cylinder 26 so as to be connected to a substituting gas system 21 and an operating gas system 23 respectively. When electromagnetic valve operating power is lost, electromagnetic valves 22 and 15 shut off an inert gas supplied from an inert gas source 16 while also the electromagnetic valve 25 is shut, and consequently the pressure of gas for operating cylinder valves 5, 7 is reduced so that the device may be set in its substituted gas operating condition that the valve 7 is opened while the valve 5 is shut. Then an inert gas from the auxiliary inert gas cylinder 26 is supplied to a fuel reformer 2, a gas supply system 4 and an air supply system 3 respectively via the electromagnetic valve 24 and the substituting gas system 21 so as to substitute the auxiliary gas for the live one. Thus operation of the device can be safely stopped without wastefully consuming the live inert gas when the electromagnetic valve operating power is lost, while the device can be kept in restartable standby condition. |
