PURPOSE:To simplify the strucure of a power generating system and save its power by comprising the power generating system using a number of fuel cell stacks and controlling an air supply blower connected to each stack by means of a common inverter. CONSTITUTION:A power generating system is comprised by using a number of fuel cell stacks (S) consisting of negative electrode sections (H) that supply reforming hydrogen gas, positive electrode sections (A) that supply air, and electrolytic sections (E). Then blowers (B) driven by three-phase induction motors (M) are provided in the air supply path of each stack (S) and are controlled by a common inverter IV that detects and controls the current to a load (L). Furthermore, the dummy reactance (L) is connected in parallel with each motor (M) and the dummy reactance is set to the L side and controlled by switches (SW) when the specified stack (S) is stopped. As a result, the system can be simplified and its power can be saved. |
