FUEL CELL SYSTEM AND CONTROL METHOD THEREOF

A fuel cell system includes a gas-liquid separator, a circulation flow path, a connecting flow path, and a distribution flow path. The gas-liquid separator separates fuel exhaust gas, which flows therein via a fuel exhaust gas flow path, into a gas and a liquid. The circulation flow path causes a ga...

Beschreibung
Zusammenfassung:	A fuel cell system includes a gas-liquid separator, a circulation flow path, a connecting flow path, and a distribution flow path. The gas-liquid separator separates fuel exhaust gas, which flows therein via a fuel exhaust gas flow path, into a gas and a liquid. The circulation flow path causes a gas discharge port of the gas-liquid separator and the fuel gas supply flow path to be in communication with each other. The connecting flow path causes a liquid discharge port of the gas-liquid separator to be in communication with the oxygen-containing gas supply flow path, via a drain valve. The distribution flow path causes the fuel gas supply flow path or the circulation flow path to be in communication with the oxygen-containing gas supply flow path, via an opening and closing valve.
