Abstract
A power supply device comprises a secondary cell group and a fuel cell group. The secondary cell group has an operative voltage range and may receive a voltage converted from a voltage converter that coupled to the fuel cell group. The fuel cell group is characterized with a maximum output power and a corresponding voltage. The corresponding voltage is not higher than the upper limit of the operative voltage range.

3. A power supply device, comprising:
-
a secondary cell group comprising an operative voltage range;
a fuel cell group comprising a fuel cell voltage and a control unit coupled between the fuel cell group and secondary cell group, outputting a first voltage within the operative voltage range to the secondary cell group when the fuel cell voltage is outside the operative voltage range, wherein the control unit outputs a first output voltage from the fuel cell group to the secondary cell group when the first output voltage is within the operative voltage range.
