Fuel cells are envisioned as the more efficient way to power automobiles in the future. Hydrogen gas is being sought as an ideal fuel. However, the low density of hydrogen molecules makes efficient hydrogen storage a challenge. At present, the target value for hydrogen storage by the DOE is set at 6.5 wt % for a realistic hydrogen commercialization. Recent efforts to store hydrogen were made using compressed gas tanks, porous sorbents and metal hydrides, to name a few, but none is able to meet the DOE cost and performance targets. Recently, a new series of porous materials termed Microporous Metal Organic Materials (MMOM) are found to be promising for hydrogen storage. Several new MMOM and their hydrogen adsorption properties are presented. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA, 8/22-26/2004).
