FUEL CELL SYSTEM AND MAXIMUM POWER CALCULATION METHOD

摘要

Provided is a fuel cell system capable of reducing a calculation error of the maximum power output from a fuel cell. An output for updating the output characteristics of the fuel cell 40 based on the fuel cell 40 generating power by the supply of the reactive gas and the output current and output voltage measured by the current sensor 140 and the voltage sensor 150. Whether or not the maximum power calculation means for calculating the maximum power outputable in the fuel cell 40 using the characteristic update means, the output characteristic, and whether or not the value of the output characteristic is temporarily assumed to be lowered temporarily. And determining means for determining, while the maximum power calculating means calculates the maximum power by using the output characteristic updated by the output characteristic updating means immediately before the transition to the assumed situation while the determination means determines the assumed situation. do.
