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.

摘要： A humidifier for a fuel cell includes a body, first and second humidifying spaces formed inside the body, an exhaust gas inlet and an exhaust gas outlet for supplying exhaust gas released from the fuel cell stack into the first and second humidifying spaces, a passing space formed inside the body and directly or indirectly communicated with the second humidifying space and the fuel cell stack. The inflow gas flows into the passing space from the first humidifying space. A valve is installed in the passing space to allow the inflow gas introduced into the passing space to flow into the fuel cell stack with or without passing through or to allow some of the inflow gas introduced into the passing space to flow into the fuel cell stack passing through the second humidifying space and others of the inflow gas introduced into the fuel cell stack without passing through the second humidifying space.

摘要： An apparatus and a method for controlling a humidification amount of a membrane humidifier for a fuel cell are provided. The humidification amount of the membrane humidifier relative to air supplied to a stack is changed by adjusting a difference in partial pressure of moisture between the inside and the exterior of a hollow fiber membrane that constitutes the membrane humidifier for a fuel cell.
