A fluid storage and delivery system utilizing a porous metal matrix that comprises at least one Group VIIIB metal therein. In one embodiment, the porous metal matrix forms a solid-phase metal adsorbent medium, with an average pore diameter of from about 0.5 nm to about 2 nm and a porosity of from about 10% to about 30%, which is particularly useful for sorptively storing and desorptively dispensing a low vapor pressure fluid, e.g., ClF3, HF, GeF4, Br 2, etc. In another aspect, the porous metal matrix forms a solid-phase metal sorbent with an average pore diameter of from about 0.25 μ m to about 500 μm and a porosity of from about 15% to about 95%, which can effectively immobilize low vapor pressure liquefied gas.
