摘要： A hydrogen consumption measuring method for a fuel cell system includes steps of: calculating an amount of hydrogen consumed for a representative section from a first pressure at a time when hydrogen is supplied into an anode and a second pressure at a time when the hydrogen is no longer supplied to the anode; and calculating a total amount of hydrogen consumed by accumulating amounts of hydrogen consumed from a plurality of sections.

摘要： A system for measuring pressure of an in-tank regulator includes a direct-pipe flow path which directly communicates with an inside of a high-pressure container, a high-pressure sensor, of which a portion is movable into the direct-pipe flow path, fastened to and separated from the direct-pipe flow path, and a shut-off valve disposed on the direct-pipe flow path between the high-pressure container and the high-pressure sensor, wherein when the high-pressure sensor is separated from the direct-pipe flow path, the direct-pie flow path is sealed by the shut-off valve.

摘要： A system for controlling low-temperature starting of a fuel cell vehicle includes a high-pressure hydrogen flow control valve controlling a flow of hydrogen supplied to a fuel cell stack. A fuel cell controller is configured to change and control an opening rate of the high-pressure hydrogen flow control valve when an internal temperature of the fuel cell stack is a reference value or less. When the opening rate of the high-pressure hydrogen flow control valve decreases, a pressure of the hydrogen passing through the high-pressure hydrogen flow control valve decreases to increase a temperature of the hydrogen which is supplied to the fuel stack.
