Abstract
Abstract A hydrogen storage and supply device in which a pressure vessel contains a hydride of the gross formula ABnHm, in which A is calcium or one or more of the rare earth metals with or without thorium, zirconium, or hafnium, B is nickel and/or cobalt, with or without iron and/or copper, n has a value between about 3 and 8.5 and m has a value exceeding 0 and up to about 7.
