FUEL CELL SYSTEM OPERATION METHOD AND FUEL CELL SYSTEM

摘要

In a fuel cell power source system comprising a fuel cell, a fuel supplier for supplying a fuel to the fuel cell, an electricity storing member capable of charging and discharging an energy, and a control circuit for controlling outputs of the fuel cell and the electricity storing member and the fuel supplier for supplying a power to an external load, there are provided a method of operating the fuel cell power source system and a fuel cell system promoting safety of the fuel cell system and reducing a deterioration in the fuel cell by removing the fuel remaining at inside of the fuel cell after stopping the fuel supplier. At an initial stage of supplying the power to the external load and inside of the fuel cell system, the power is supplied from the electricity storing member, and the electricity storing member is charged by using an output outputted from the fuel cell by generating the power by the fuel cell by using the fuel remaining at inside of the fuel cell system after stopping the external load.
