FUEL CELL SYSTEM

摘要

A fuel cell system includes: a fuel cell; a coolant path connected to the fuel cell and allowing a coolant that cools the fuel cell to flow therethrough; a temperature detection unit configured to detect a temperature of the coolant in the coolant path; a temperature correction unit configured to calculate a temperature correction value by correcting the temperature of the coolant detected by the temperature detection unit; and a lower limit voltage control unit configured to control a lower limit voltage of the fuel cell based on the temperature correction value, wherein the temperature correction unit calculates the temperature correction value based on a following equation: (see above formula) where T filt represents the temperature correction value, T filt_old represents a last temperature correction value, T represents the temperature of the coolant, and .tau. represents a coefficient, and the coefficient when the temperature of the coolant is less than a first predetermined value is set to be greater than the coefficient when the temperature of the coolant is equal to or greater than a second predetermined value.
