FUEL CELL POWER GENERATION SYSTEM AND METHOD FOR CONTROLLING SAME

The present invention includes a power generation section (8); an internal load (4, 6, 9, 10); an inverter (7); a voltage detector (12) and a current detector (11, 21); and a controller (6). The controller is configured to estimate a value of a current supplied to the internal load based on at least one of the current value detected by the current detector and an operation amount of the internal load, and control the inverter and the internal load based on the current value detected by the current detector and the estimated current value so that the electric power generated in the power generation section reaches the target electric power.
