In the actual operation of a hydrogen fuel cell, water is inevitably discharged out of the cell along with hydrogen off-gas due to the humidification of water and the presence of water in the reaction product. And the hydrogen enters a hydrogen circulating pump together to be reused. Water in the hydrogen tail gas can increase the work load of hydrogen circulating pump, even causes hydrogen circulating pump work badly, and water in the hydrogen tail gas constantly gathers simultaneously, can block battery hydrogen passageway when serious, induces battery work badly.

At present, CN109173548A is a cyclone type high-efficiency water-vapor separator, and discloses that water vapor enters a tank body and then rotates around a spiral guide plate, so that the water vapor is separated under the action of centrifugal force, but the structure is easily influenced by the speed of the water vapor, and when the speed of the water vapor is smaller, the separation effect is poorer. CN1786472 is a cyclone water-gas separator with baffles, and discloses that the flow speed of water vapor is improved by a cyclone separation disc, and the impact separation effect is improved by the baffles, so that the water-gas separation effect is improved. However, because the arrangement positions of the air inlet, the air outlet, the cyclone separation disc and the baffle are unreasonable, turbulent flow is easily generated in the separation chamber, and the integral effect of water-vapor separation is affected.

In order to solve the above problems, it is necessary to improve the existing water-vapor separator to improve the separation effect of water in the hydrogen off-gas, thereby reducing the workload of the hydrogen circulation pump and avoiding the influence on the operation of the hydrogen battery.
