As disclosed, there is provided a small-size power system for fuel cell allowing efficient extraction of electric power-output from a fuel cell and a secondary cell, electronic equipment, and an electric power feeding method. The power system for fuel cell has a voltage conversion circuit and a rectification circuit, and is structured such that output voltage of the fuel cell is converted with a set voltage, which is an output voltage corresponding to a maximum electric power-output of the fuel cell, as a reference to produce a switch voltage, and at least either the switch voltage or an output voltage of the secondary cell is outputted through the rectification circuit. This allows parallel operation of the fuel cell and secondary cell in a state that the electric power of the fuel cell can be utilized to the full.
