Mg와 다른 합금(예를 들면 MgNi)을 혼합물로부터 형성된 수소흡장 베이스(2)와, 그 수소흡장 베이스(2)의 표면을 덮는 촉매층(3)을 구비하였다. 이것에 의해, Mg가 갖는 높은 수소흡장 성능과, MgNi가 갖는 높은 고체 확산 성능을 겸비한 수소흡장 합금을 얻을 수 있다. Mg에 흡장된 수소는, MgNi에 의해 다른 Mg(또는 MgNi)에 전달된다. 이 수소의 이동은, 열이나 압력을 필요로 하지 않는다. 이 때문에, 실온·대기압하에서 수소를 흡장할 수 있다.

    A hydrogen storage alloy comprises a hydrogen storage base 2 formed of a mixture of Mg and an alloy (Mg 2 Ni, for example), and a catalytic layer 3 covering a surface of the hydrogen storage base 2. The hydrogen storage alloy with this structure exhibits both a high ability to store hydrogen and a high ability to cause hydrogen to diffuse in it in the solid state, provided by Mg and Mg 2 Ni, respectively. Hydrogen absorbed in Mg in one region is passed on to Mg (or Mg 2 Ni) in another region by virtue of Mg 2 Ni. Since this movement of hydrogen does not require heat nor pressure, hydrogen can be absorbed at room temperature and atmospheric pressure.
