Fuel cartridges for fuel cells are disclosed. One fuel cartridge has an outer casing, an inner liner containing fuel, and a valve component adapted to transport fuel from the fuel supply to a fuel cell. The outer casing and the inner liner are made by blow molding and as the fuel is transported from the fuel supply, the inner liner pulls away from the outer casing. Another fuel cartridge includes an outer casing, an inner liner containing fuel, and a valve component adapted to transport fuel from the fuel supply to a fuel cell. The inner liner is integral to the outer casing at a region proximate to the location of the valve component. The inner liner and/or the outer casing can be fluorinated, coated with a barrier material or wrapped with a barrier film to reduce vapor permeation.
