Patent ID: 8486581

Claim:
A fuel cell system, comprising: a fuel cartridge, comprising: a plurality of chambers, each of the chambers being capable of storing a first reactant; and a plurality of supply devices, respectively corresponding to the chambers, and each of the supply devices being capable of supplying a second reactant to the corresponding chamber, so that the second reactant reacts with the first reactant in the corresponding chamber to generate hydrogen gas; a fuel cell, coupled to the fuel cartridge, the fuel cell being capable of absorbing the hydrogen gas from the fuel cartridge so as to generate an electric-power; and a secondary battery, electrically connected to the fuel cell, the secondary battery being capable of receiving the electric-power for charging, wherein the fuel cell is capable of absorbing the hydrogen gas generated from one of the chambers in the fuel cartridge to generate the electric-power, wherein the number of the chambers is X; a capacitance of the secondary battery is N watt-hour; and an electric quantity of the electric-power is N/X watt-hour when the fuel cell generates the electric-power by absorbing the hydrogen gas generated from one of the chambers in the fuel cartridge.
