Abstract
A storage tank for a gas is provided. The storage tank includes a liner defining an internal compartment; a boss coupled to the liner; an interlayer covering a portion of the boss and the liner, the interlayer being non-pyrolyzed and including an interconnected web and pores having a diameter greater than the diameter of a hydrogen molecule and less than or equal to about 2 nm; and an outer shell including a carbon fiber reinforced composite, the outer shell covering the interlayer, except for an interlayer end that is in contact with the boss, so that the interlayer end defines an interlayer ring that is exposed to an external environment. The storage tank is configured so that when gas diffuses through the liner to the interlayer, the interlayer channels the gas out of the exposed interlayer ring. Methods of fabricating the storage tank are also provided.
