Absorbent media for gas or heat is provided in a predetermined length of a polygon or curvilinear, and preferably honeycomb (hexagonal) cross sectioned shape with gas absorbent media packed therein. The hexagonal tubes may be installed along the radial or longitudinal axis of a fuel tank. The media and/or media tubes are installed during tank manufacture and include defined physical and gas circulation relationships for maintaining extending tubes having a gas absorbent media therein in a predetermined interrelationship with adjacent spaces (which may be tubes) of similar shape that are either open, or filled with a heat absorbent media.

The tank of claim 1 wherein the internal heat exchanger is centrally positioned within the tank along the lengthwise axis of the tank and the tubes or rods are disposed perpendicularly with respect to the heat exchanger such that the tubes or rods occupy a portion of the volume of the tank and surround the volume of the tank occupied by the heat exchanger in the tank. 3. The tank of claim 1 wherein the internal heat exchanger is centrally positioned within the tank along the lengthwise axis of the tank and the tubes or rods are disposed along the lengthwise axis of the tank such that the tubes or rods essentially fill the volume of the tank and surround the volume occupied in the tank by the heat exchanger. 4. Storage tank apparatus for the refueling and exhaustion of high pressure fuel gas in an on board vehicle fuel tank including: a) a plurality of donut shaped laminated disks arranged in a sequential assembly, the disk assembly comprising a pair of gas permeable support plates between which an arrangement of separate extending tubes or rods comprising either a gas absorbent media or heat absorbent media is disposed, the tubes or rods being coaxially arranged with respect to the upper pair of support plates for the assembly, the plurality of disk assemblies being spaced apart within the tank along the lengthwise axis thereof;b) an internal heat exchanger centrally located within the center opening of the donut shaped disks, the heat exchanger extending along the lengthwise axis of the tank and being disposed within the tank such that the heat exchanger is concentrically surrounded by the disks;c) a heat exchanger external to the tank;d) a gas flow circuit defining gas flow into, through and from the tank, the internal heat exchanger, and the external heat exchanger, wherein gas is circulated depending on the operational mode of the vehicle on which the tank is installed such that, in a refill mode, gas from a refuel depot introduced into the internal heat exchanger for circulation therein flows into the external heat exchanger where heat absorbed from the gas in the tank is exhausted before the gas enters the tank for storage, and, in a driving mode, before gas in the tank is conveyed to the vehicle power plant, the gas flows from the tank in the flow circuit into the external heat exchanger where gas is warmed and then introduced into the internal heat exchanger whereby the gas otherwise stored in the tank is warmed. 5.
