Abstract
A fuel cell system includes a fuel cell, a battery, and a DC/DC converter capable of connecting the fuel cell and the battery on a power feeding circuit. A method of starting operation of the fuel cell system includes the steps of connecting a bypass line connected to a battery for bypassing the DC/DC converter to the power feeding circuit, and directly supplying electrical energy from the battery to an air compressor of an oxygen-containing gas supply apparatus through the bypass line in a state where the fuel cell is disconnected from the power feeding circuit.
Claims4
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 during a startup operation of the fuel cell system in a state where the fuel cell is disconnected from the power feeding circuit.
