Abstract

Among the major problems in making the hydrogen-powered fuel cell vehicles feasible in practice is the on-board storage system for hydrogen. The DOE has set target system energy densities at value of 6.5 wt % and 62 kg H2/cu m by 2010. The effect of dopants, such as carbon and titanium, in the hydrogen storage kinetics of hydrides such as alanates and borates at an atomic level using theoretical/computational methods was studied. The role of dopants in desorption kinetics of these hydrides was characterized. The effect of dopants on the metal-hydrogen bonding nature was examined using the total and the partial electronic density of states and the electronic charge distributions before and after doping. This is an abstract of a paper presented at the AIChE Spring National Meeting (Houston, TX 4/22-27/2007).
