    摘要： A stack ventilation system includes a supply line that supplies a supply gas to an air electrode of a fuel cell stack, a discharge line that discharges an exhaust gas released from the air electrode, and a stack supply line that branches off from a branching point of the supply line and that supplies the supply gas in the supply line to a stack enclosure in which the fuel cell stack is accommodated.

    摘要： An air control valve for a fuel cell vehicle includes: a valve housing having a first port and a second port; a first rotary shaft rotatably mounted in the valve housing and configured to be rotated by a driving source; a first valve member connected to the first rotary shaft and configured to selectively open or close the first port by rotating about the first rotary shaft; a second rotary shaft mounted in the valve housing so as to be rotatable relative to the first rotary shaft; a second valve member connected to the second rotary shaft and configured to selectively open or close the second port by rotating about the second rotary shaft; and a spring member connected, at one end thereof, to the first rotary shaft and connected, at the other end thereof, to the second rotary shaft, thereby improving stability and reliability.

    摘要： An air shut-off valve apparatus for a fuel cell system is provided. The apparatus includes a valve body having an inlet-side air passage through which supply air flows and an outlet-side air passage through which exhaust air flows. A valve flap is installed in the valve body to open or close the inlet-side air passage and the outlet-side air passage. An inlet-side check valve is opened when pressure of the supply air is greater than or equal to a predetermined pressure, to guide the supply air into the fuel cell stack through the inlet-side air passage even while the valve flap is closed. An outlet-side check valve is opened when pressure of the exhaust air is greater than or equal to a predetermined pressure, to guide the exhaust air released from the fuel cell stack to flow through the outlet-side air passage even while the valve flap is closed.
