    摘要: A controller for a fuel cell power system comprises a main switching element inserted between a fuel cell power unit and a dc-ac converter, a secondary battery connected to a charging switching element and a discharging switching element, and a control circuit for switching elements, the charging switching element and discharging switching element being connected in series and across the main switching element. The secondary battery is charged by turning on the charging switching element when the fuel cell power unit is in warming up operation or when the dc-ac converter is broken off from the output circuit of the power unit to stop the operation of the fuel cell power unit, while the battery is discharged through the dc-ac converter by turning on the discharging switching element when the fuel cell power unit reaches the rated operating temperature.
