A pressure vessel is provided having an outer support layer having an inner surface; a composite wrap disposed adjacent to the inner surface; and a liner disposed adjacent to the fiber composite wrap. Further provided is an adapter disposed at a first end of the pressure vessel and configured for charging a cavity formed by the pressure vessel with a compressed fuel, wherein the adapter includes a first pressure relief device; and a second pressure relief device disposed at a second end of the pressure vessel. The second pressure relief device defines a passage through the outer support layer and the composite wrap and has a chamber and a diaphragm disposed between the chamber and the cavity. Also described are a fuel cell propulsion system and a vehicle including the provided pressure vessel.
