Abstract
A voltage supplying apparatus using fuel cell to be a voltage source is provided. The voltage supplying apparatus comprises a fuel cell, a DC-DC voltage converter and a control circuit. The DC-DC voltage converter is used to receive the voltage outputted from the fuel cell and then output another voltage. Then, the voltages outputted from the fuel cell and the DC-DC voltage converter are combined to be the output voltage of the voltage supplying apparatus. The control circuit is used to control the operation of the DC-DC voltage converter according to magnitude of the output voltage of the voltage supplying apparatus.
