[en] In the present study, hydrogen absorption experiments using Zr(zirconium) and Ti(titanium) in the form of metal sponge, strip and rod were carried out to investigate the hydrogen absorption characteristics with reaction temperature, the type of metal, activation conditions, and the presence of helium in hydrogen. Zr and Ti sponges showed a high hydrogen absorption capacity inspite of a low reaction temperature. The H/M which indicates the capacity of hydrogen absorption, was measured at 2.0 for the Zr/Ti sponge under experimental condition of 25 .deg. C. However, in the case of the Zr/Ti strip and rod, the hydrogen absorption capacity was very low at 25 .deg. C
