    摘要: A hydrogen absorbing alloy is provided which is increased in reaction rate without being restricted in composition and which is unimpaired in the reversibility of reaction and hydrogen absorption-desorption cycle life characteristics. The alloy contains the phase of an intermetallic compound of the composition A5T19 wherein A is at least one element selected from the group consisting of La, Ce, Pr, Sm, Nd, Mm (misch metal), Y, Gd, Ca, Mg, Ti, Zr and Hf, and T is at least one element selected from the group consisting of B, Bi, Al, Si, Cr, V, Mn, Fe, Co, Ni, Cu, Zn, Sn and Sb. The alloy is produced by mixing together an alloy containing an AT3 phase and an alloy containing an AT4 phase, mechanically alloying the mixture to form the phase of intermetallic compound of the composition A5T19 in addition to the AT3 and AT4 phases, and subsequently mixing together or mechanically alloying the resulting alloy and an alloy containing AT5 phase.

    摘要: Molded bodies of a hydrogen absorbing alloy accommodated in a hydrogen storage container are made readily replaceable to ensure stabilized supply of hydrogen gas. When exhibiting an impaired hydrogen absorbing-desorbing capacity, the molded bodies can be easily replaced by new molded bodies, whereby a specified hydrogen absorbing-desorbing capacity can be maintained. The hydrogen gas released from the storage container is partly utilized to heat the container and thereby maintain the alloy at a predetermined temperature, consequently assuring a device, such as a fuel cell, of stabilized supply of hydrogen from the container.
