Title: Electrochemical cell

Abstract

This patent describes an electrochemical cell comprising a negative electrode. It comprises an electrochemical active material consisting of an intermetallic compound of the formula AB{sub m}C{sub n} wherein m plus n is between 4.8 and 5.4, n has a value of up to 0.6 and greater than 0, A is a Mischmetall or at least one element of the group consisting of Y, Ti, Hf, Zr, Ca, Th, La and the remaining rare earth metals, B is at least two elements selected from the group consisting of Ni, Co, Cu, Fe and Mn and C consists of at least one element selected from the group consisting of Al, Cr, and Si, and has a CaCu{sub 5} structure, and a catalytic material at the surface of which hydrogen exhibits a large electrochemical activity, the catalytic material having a composition of formula DE{sub 3} wherein D is at least one element selected from the group consisting of Cr, Mo and W and E is at least one element selected from the group consisting of Ni and Co.
