いう欠点がある。(bJ Jubei Technology Recently, many hydrogen storage materials have been invented as Numa 1 materials.In particular, iron-titanium intermetallic compounds?FeTi is important because it has excellent hydrogen storage properties and is inexpensive.However, There are drawbacks such as the need for high temperature and high pressure for oxidation, and the gradual decrease in the absorption amount due to absorption and desorption during conversion.On the other hand, known techniques include adding Nb, etc., dispersion of oxides in the iron-titanium composition, and oxygen absorption. Stabilization methods have already been proposed as a method for improving iron-titanium hydrogen storage materials.Furthermore, AB5-type rare earth intermetallic compounds are also considered promising because they are easy to activate, but La The disadvantage is that they are expensive.
