Abstract: A water management system reduces the problems with flooding and also enhances the flow of fuel gas to the anodes. Individual unit cells (20) in an array are separated by cell walls (24), the array is covered by a fuel manifold (36), and the manifold is arranged so that the individual unit cells have their own respective chambers. Each chamber is arranged so that the fuel gas flows from one chamber into another through an opening or vent (35) in the chamber wall. The opening contains a hydrophobic portion (38) that serves to urge liquid water that accumulates in the opening to migrate away.

Abstract: A holster (100) includes an adjustable depth pocket (101) for receiving at least a portion of a portable radio (102) in the pocket (101). The portable radio (102) includes an interface, such as a user interface (120, 122), and the holster (100) includes access openings (124, 126). An adjustable false bottom (130) in the pocket (101) is adjustable to provide a variable depth in the pocket (101). When the portable radio (102) is received in the pocket (101) the user interface (120, 122) and the access openings (124, 126) are substantially aligned thereby the user interface (120, 122) is accessible from outside the holster (100) via the access openings (124, 126).
