1. A method of starting operation of a fuel cell system, the fuel cell system including:

  • a fuel cell for generating electricity by electrochemical reactions of a fuel gas supplied from a fuel gas supply apparatus and an oxygen-containing gas supplied from an oxygen-containing gas supply apparatus; and

    a DC/DC converter capable of connecting the fuel cell and an energy storage on a power feeding circuit,the method comprising the steps of;

    connecting a bypass circuit connected to the energy storage, for bypassing the DC/DC converter, to the power feeding circuit; and

    directly supplying electrical energy from the energy storage to an air pump of the oxygen-containing gas supply apparatus through the bypass circuit in a state where the fuel cell is disconnected from the power feeding circuit.
