FUEL CELL SYSTEM AND START METHOD THEREOF

摘要

There are provided a fuel cell system 10 and a starting method therefor, capable of setting a start-up mode which is appropriate to energy stored in a secondary battery 108, eliminating a trouble in starting the fuel cell system. The fuel cell system 10 includes: a fuel cell 12; a secondary battery 108 which is electrically connected with the fuel cell 12; a secondary-battery charge-amount detection unit 112 which detects an amount of charge in the secondary battery 108; and memory means which stores at least one threshold value for determining the start-up mode of the fuel cell system 10. Stored electric energy which corresponds to the amount of charge in the secondary battery 108 is calculated, and a start-up mode of the fuel cell system 10 is determined based on the electric energy stored in the secondary battery 108 and the threshold value stored in the memory means.
