Abstract: A venting device for insertion into an opening (2) of an enclosure having a wall (3) with an interior surface and an exterior surface comprises a body (11; 21; 31) having an insertion portion (12; 22; 32) for insertion into the opening (2) of the enclosure and a head portion (13; 23; 33). The body (11; 21; 31) has a passageway (14; 24; 34) that extends through the insertion portion (12; 22; 32) and the head portion (13; 23; 33) for passage of a fluid from the enclosure (7) to the ambient environment (6). The venting device further comprises an air permeable, water impermeable venting element (15; 25; 35) covering the passageway (14; 24; 34). An engagement section (16; 26; 36) is arranged circumferentially about the insertion portion (12; 22; 32) for engagement with the wall (3) of the enclosure.

Abstract: An apparatus and method of manufacturing a fuel storage tank for a fuel cell system used for storing various pressurized fluids having separate permeation characteristics for reducing permeation leakage during various temperature and pressure cycles. The fuel storage tank comprises a formed liner to define an inner cavity, as well as a boss connected to the liner, a reinforcement structure formed around a portion of the boss and the liner, a permeation bag affixed to a first securing member and inserted into the inner cavity of the liner. The first securing member is coupled with the boss and a second securing member is assembled to the boss adjacent the first securing member to secure a fluid tight connection between the permeation bag, the liner and the boss.
