Abstract
The invention relates to an electrochemical cell comprising a negative electrode of a stable hydride-forming material, in which a large loading capacity at low temperature is obtained by the addition of a catalytic material of the type DE.sub.3, wherein D is one or more of the elements selected from Cr, Mo and W, and wherein E represents Ni and/or Co. The catalytic material can be provided in the form of a eutectic segregation or it can be provided at the surface of powdered hydride-forming material by means of an electrochemical reaction.
