Abstract
The present invention is a solid oxide fuel cell system for generating variable power in response to power demand, having: a fuel cell module; a fuel supply device; a power demand detection device; a controller for controlling the amount of fuel supplied by the fuel supply device based on the power demand, and for setting an extractable current value, being the maximum extractable current value; an inverter for extracting current from the fuel cell module within a range not exceeding the extractable current value; and an extractable current detection device for detecting actual extracted current extracted from the fuel cell module; whereby if certain increase-limiting condition is matched, then even when power demand is rising, the controller maintains the extractable current value at a certain value, or lowers the extractable current value, and does not increase that extractable current value.
