  "textContent": "An electric power control apparatus is for a fuel cell system including an impedance measurement unit that measures an impedance of the fuel cell based on a current and a voltage measured when alternating-current electric power is superimposed on output electric power of the fuel cell. A processor of the electric power control apparatus: estimates a remaining capacity of the electric power storage device after execution of a process of measuring the impedance; performs charging and discharging of the electric power storage device before start of the process of measuring the impedance, to make the estimated remaining capacity fall within a predetermined range from a lower limit value to an upper limit value; and controls electric power generation of the fuel cell to make a generated current of the fuel cell constant, during the execution of the process of measuring the impedance.",
