A device ( 150, 250 ) for recovering liquid droplets from a fluid flow stream containing the liquid droplets entrained therein includes a rotatable element ( 164, 256 ) formed with a partially enclosed fluid volume ( 184, 262 ). The fluid is injected into the partially enclosed fluid volume while the rotatable element ( 164, 256 ) is being rotated. The rotation generates a centrifugal force capable of moving liquid droplets deposited onto inside surfaces of the partially enclosed fluid volume ( 184, 262 ) to a perimeter wall inside surface ( 172, 284 ) and to hold a layer of liquid against the inside surface ( 172, 284 ). An output liquid conduit ( 208, 286 ) is formed to enter into the partially enclosed fluid volume ( 184, 262 ) and to position a collection aperture ( 212, 290 ) proximate to the inside surface ( 172, 284 ) for collecting liquid from the layer of liquid held against the inside surface ( 172, 284 ). The device ( 150, 250 ) is usable to recover liquid water from the outflow of a hydrogen fuel cell system ( 100 ).
