Abstract
A pressure vessel for the storage of pressurized fluids for a fuel cell system, a liner for the pressurized vessel and a method of making. The method of manufacturing a pressure vessel includes forming a lost core assembly, a reinforcement structure around the assembly and removing the core from said assembly to define an internal compartment. The lost core assembly includes a first sacrificial material used to define the shape of the pressure vessel's internal compartment, boss attachable to the first material for the introduction and removal of the fluid into the pressure vessel, and a second material for placement around the first material and at least a portion of the boss such that upon removal of the first material, the second material defines the liner. The reinforcement structure is wound around the liner to give the pressure vessel a unitary, composite structure.
