Claim Text:
1. A solid oxide fuel cell system for generating electrical power variable in response to power demand, comprising: a fuel cell module configured to generate electricity by reaction of fuel; a fuel supply device configured to supply the fuel to the fuel cell module; a power demand detection device configured to detect the power demand; an inverter operable to extract electrical current from the fuel cell module and output the extracted current in alternating form; a controller programmed to an extracted current detection device configured to generate an actual current signal indicative of a value of current extracted from the fuel cell module by the inverter, wherein the controller is further programmed to vary the extractable current signal to increase the maximum extractable current value at different increase rates in such a manner that the maximum extractable current value is increased at a higher increase rate when a degree to which the target current signal is higher than the actual current signal is greater so as to allow the inverter to extract more current from the fuel cell module when the degree to which the target current signal is higher than the actual current signal is greater.
