Abstract:
To provide a gas-liquid separator capable of preventing a fuel gas in a case from being discharged from a drainage channel to the outside of the case even when a drain valve provided in the drainage channel is opened in a state where the case is tilted so that the position of the drain valve is high.SOLUTION: A gas-liquid separator 15 causes hydrogen discharged from a fuel cell stack to flow into a case 20 to separate hydrogen from water, store the water in a water storage area 25 located at a lower end portion of the case 20, and then drain the water through a drainage channel 27 to the outside of the case 20. The drainage channel 27 is provided at a lower end portion of a second side wall 26 of the case 20 so as to penetrate through the second side wall 26, and a drain valve 28 is provided at a downstream end of the drainage channel 27. Below the drainage channel 27 in the case 20 is provided a bypass passage 30 which has one end communicating with an end portion of the water storage area 25 on an opposite side to the drainage channel 27 and the other end connected to a middle position of the drainage channel 27.SELECTED DRAWING: Figure 2
