PURPOSE:To obtain a fuel-cell generating system, which can prevent any cross over by regulating the pressure difference caused by rapid load variation, by installing gas tanks in the exhaust paths of a fuel gas and an oxidant gas, providing a means for adjusting the pressure of the outlet side for the fuel gas to a standard value, and providing a means for adjusting the pressure difference between the outlet side for the oxidant gas and the inlet side for the fuel gas to a standard value. CONSTITUTION:A highly reliable operation of a fuel cell is enabled by regulating the pressure difference between a fuel gas and an oxidant gas to the above mentioned state by adjusting a differential pressure detector 18 provided between the inlet side for the fuel gas and the outlet side for the oxidant gas to a given value. By thus providing controllers 13 and 17, respectively, on the outlet sides for the fuel gas and the oxidant gas, the flowing amounts of the fuel gas and the oxidant gas can be regulated in response to the load variation, and the pressure difference caused by the load variation can be controlled within the accuracies of adjustment valves 14, 15, 20 and 21, within a high accuracy. Consequently, a highly economic fuel-cell generating system with a high reliability can be obtained. |
