Method and apparatus for making a fuel storage tank with a liner and inner bag for a fuel storage system

A method of manufacturing a fuel storage tank for a fuel cell system such that a formed portion of said fuel storage tank comprises a single layer liner defining an inner cavity, at least one boss formed in an opening of said liner and a reinforcement structure formed around at least a portion of said at least one boss and said liner, said method comprising:

• affixing a permeation bag to a first securing member;
• inserting said permeation bag into said inner cavity;
• coupling said first securing member with said at least one boss;
• and
• assembling a second securing member to said at least oneboss adjacent said first securing member to secure a connection between said permeation bag and said fuel storage tank.

A hydrogen storage tank for a fuel cell system, said hydrogen storage tank comprising:

• a generally axisymmetric liner formed to define an inner cavity of said hydrogen storage tank;
• at least one boss connected to an opening formed in at least one end of said liner;
• a reinforcement structure formed around at least a portion of said at least one boss and said liner;
• a permeation bag affixed to a first securing member wherein said permeation bag is inserted into said inner cavity, said first securing member is coupled with said at least one boss and a second securing member is assembled to said at least one boss adjacent said first securing member to secure a connection between said permeation bag, said liner and said at least one boss.
