PURPOSE:To provide a hydrogen storage electrode for forming a sealed battery which has the drastically less cell internal pressure generated in electric charge and can be manufactured relatively at low cost. CONSTITUTION:An electrode is made of the hydrogen storage alloy which is represented by a general formula MmNiaCobAlc (3.0<=a<=3.5, 0.7<=b<=1.3, 0.3<=c<=0.6, 4.0<=a+b+c<=5.2), and an La content in Mm of 80wt.% or more. |
