NOVELTY - A fuel supply comprises outer casing (12), and fuel container. The fuel container contains methanol for the fuel cell. A material capable of producing a positive vapor pressure as the methanol is transported from the fuel container. The material is contained in a space between the outer casing and the fuel container. The vapor pressure material comprises a second fuel. The second can also be methanol. A portion(s) of the vapor pressure material is contained within an absorbent mechanism made of porous material, filler material, or foam. The outer casing comprises a check valve.    USE - The fuel supply is useful to be connected to fuel cell, and used to store fuels, e.g. hydrogen fuels , e.g. for micro gas turbine engine, internal combustion engines, and pocket and utility lighters.    ADVANTAGE - The fuel supply has pressure on the fuel liner equalized to reduce the stress placed on the fuel liner, minimizes the permeation of fuel from the inner fuel container to the atmosphere, and reduces permeation rate of gas in and out of the liner.    DETAILED DESCRIPTION - The outer casing includes liquid impermeable membrane cooperating with the check valve, and liquid retainer cooperating with the check valve. The vapor pressure material comprises methanol gel; subliming solid, i.e. iodine or naphthalene; or liquid, i.e. water, hydrocarbon or methane. The liquid vapor pressure material comprises a hydrocarbon, e.g. n-butane, iso-butane or propane. The outer casing is rigid. The fuel container is deformable or elastic. The fuel container is encased within an outer fuel container. A second vapor pressure material is contained in the space between the outer fuel container and the fuel container. The outer fuel container is flexible. The supply includes cushion adapted to soften impacts on the fuel container. The cushion comprises a porous medium. The vapor pressure medium is contained within the cushion. The pressure within the fuel container is the same as the pressure in the space between the outer casing and the fuel container.
