  • Publication number: 20220311032
    Abstract: When leakage of fuel gas is detected by detection signals or disruption of the detection signals is detected, a FCECU limits a supply amount of the fuel gas from a fuel gas supply device, and shuts off the supply of the fuel gas by the fuel gas supply device when determining, after limiting the supply amount of the fuel gas, that the leakage of the fuel gas or the disruption of the detection signals has occurred.

  • Patent number: 11271228
    Abstract: 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 gas and liquid. The circulation flow path causes a gas discharge port of the gas-liquid separator and the fuel gas supply flow path to communicate with each other. The connecting flow path causes a liquid discharge port of the gas-liquid separator to communicate with the oxygen-containing gas supply flow path, via a drain valve. The distribution flow path causes the circulation flow path or a portion of the fuel gas supply flow path that is on a downstream side of a connecting section connecting to the circulation flow path to communicate with a downstream side of the drain valve of the connecting flow path via an opening and closing valve.
