Water separator of vehicular fuel cell system, comprises cylindrical tube with tangential inlet, concentric gas outlet and sump forming water seal

摘要

The cyclone separator (50) cylindrical collection tube (52) internal wall, defines a collection chamber passing water-laden flow. This is swirled by the tangential inlet (54), centrifugal force separating water against the wall (58). Displaced to the outlet (56), water flows into the collection sump (70) below. A valve (78) controls sump outlet flow under level switch control, retaining sufficient water to form a seal and prevent escape of flow via the water outlet. The gas off take (66) leaves concentrically.
