A power supply system 10 with a stack of fuel cells 20 and a storage battery 30 includes a remaining charge monitor 42 for measuring the remaining charge of the storage battery 30. At the time of starting the power supply system 10, the remaining charge monitor 42 detects the remaining charge of the storage battery 30. The power supply system 10 estimates output electric current of the fuel cells 20 based on the observed remaining charge of the storage battery 30 and an amount of electric power required for auxiliary machinery 34, and supplies required a...
[ What is claimed is:] [1.] A power supply system comprising a stack of fuel cells and a storage battery, which are connected parallel to each other and also to a loading, wherein said stack of fuel cells and said storage battery supply electric power to said loading, said power supply system comprising:remaining charge detection means for detecting a remaining charge of said storage battery;amount-of-loading detection means for detecting a total amount of said loading;charge-discharge state estimation means for estimating a charge-discharge state of sai...
