摘要： A fuel cell system includes a fuel cell stack and a control device that controls operation of the fuel cell system based on a measured voltage value measured by a voltage sensor. When the fuel cell system is started and a value measured by a temperature sensor is equal to or less than a temperature determined in advance, the control device raises the voltage of the fuel cell stack until a voltage condition determined in advance is met, by supplying a cathode with an oxidant gas before current sweep is started. The control device sets a voltage command value and a current command value such that an operation point of the fuel cell stack is on an equal power line of the fuel cell stack when the operation point is caused to transition in at least a part of a transition period.

摘要： A fuel cell system may include: a fuel cell; a hydrogen gas supply passage; a solenoid valve that changes an opening degree of the hydrogen gas supply passage; a pressure sensor that detects a pressure in a downstream supply passage being a part of the hydrogen gas supply passage from the solenoid valve to the fuel cell; and a control circuit. The control circuit detects a rise in the pressure detected by the pressure sensor when increasing a conducted electric current conducted in the solenoid valve from a state where the solenoid valve is closed, and detection of a rising current which is the conducted electric current at a time of the rise in the pressure; and calculates an increase characteristic based on the rising current, the increase characteristic being a relationship between the conducted electric current and the pressure when the conducted electric current increases.
