Abstract
In this paper, a relationship between the electrochemical capacity of mechanically alloyed MgXNi100-X amorphous hydride electrodes and disch arging time is deduced on the basis of oxidation of Mg and Ni. The exp erimental data are in good agreement with the deduced relation. Analys is shown that this is the common mechanism of hydride electrode degrad ation when the activation process is ignored. The parameters m and B o f some amorphous hydrides art calculated on the basis of this relation . (C) 1997 International Association for Hydrogen Energy.
