Abstract

PURPOSE:To enable the operation of a fuel cell power generation plant to be safely and stably stopped when a rapid load variation occurs by connectig an urgency load device to the output of a fuel cell through a d.c. power control device. CONSTITUTION:The output terminal of a fuel cell 3 is connected to both a d.c. power controller 8 connected parallel to a d.c. breaker 4 and an urgency load device 9 which is connected to the controller 8 and consumes surplus d.c. electric power. When the load is cut off by an accident to the generation plant or a similar accident, alternating electric power supplied to the load instantaneously becomes zero at time point (T1). Simultaneously, the controller 8 operates to cause the load device 9 to consume an equal quantity of electricity. Accordingly the d.c. output of the fuel cell 3 does not change around time point (T1). From time point (T2) which is a given time later than time point (T1), the power consumption of the urgency load device 9 is gradually decreased by the controller 8. At time point (T3), operation of the power generation plant is stopped.

Under certain operating conditions, 1A current power is generated by an amount of hydrogen-rich gas and air supplied from the outside, and this generated DC TW power passes through the IA current breaker L It is supplied to the converter S, where it is converted into a predetermined AC gravity, and then supplied to the load via the circuit breaker 6. If a sudden change in load occurs due to different operating speeds of the fuel reformer/fuel cell main unit 3. and orthogonal conversion device mS, operational measures are taken to ensure that the plant operation follows this load change I4710. For example, when the DC breaker or breaker becomes open due to an accident on the load side, it is necessary to Even if it decreases with sufficient tracking, the fuel reformer gi
Since there is no change in the amount of hydrogen, the IC is configured so that the excess hydrogen-rich gas generated there is guided to the exhaust combustion tower 7 through a gas switching valve and then sent to the fuel injection station. In addition, in the case of -1:'>tc, the DC output of the fuel 1 and the reservoir body 3 instantaneously changes to 'C, so the consumption of fuel and air I#t suddenly becomes (The operation of the fuel cell main body 30 is 1) Three forces are required ()) A large fluctuation occurs in the differential pressure between the hydrogen-rich gas and the air.
