Abstract
A drainage system for a fuel cell, including a gas-liquid separator configured to separate fuel gas and liquid water from a gas-liquid mixture discharged from the fuel cell, a water tank configured to receive the liquid water separated by the gas-liquid separator, a drain valve in fluid communication with the water tank, the drain valve configured to selectively discharge the liquid water from the water tank, and a control unit configured to selectively open and close the drain valve. The water tank includes a lower portion having a first horizontal cross sectional area and an upper portion having a second horizontal cross sectional area, the first horizontal cross sectional area being smaller than the second horizontal cross sectional area. The control unit opens and closes the drain valve to maintain a first water level within the upper portion of the water tank when the fuel cell is in an operating state and to maintain a second water level within the lower portion of the water tank when the fuel cell is in a stopped state.
