  • Fuel cell system
    Patent number: 10629925
    Abstract: When a shut-off valve is opened, gas is discharged via a main passage which is disposed at a predetermined height from a bottom of a gas-liquid separator. Water which gathers in the bottom of the gas-liquid separator flows from a bypass passage to the main passage and is discharged when water level difference>height is satisfied. When water which gathers in the bottom of the gas-liquid separator is supercooled water, discharge of water is avoided by controlling an open pressure and a passage pressure such that water level difference<height is satisfied.
    Type: Grant
    Filed: January 17, 2018
    Date of Patent: April 21, 2020
    Assignee: Toyota Jidosha Kabushiki Kaisha
    Inventors: Takami Hosoi, Michitaro Itoga, Michihiko Masuda
