The invention relates to compact and lightweight disposable accumulators for generating electric energy with extremely high energy densities (&#x3e;1 kWh/kg and &#x3e;k Wh/liter), which are of immense interest in many areas of application. One possibility for implementing such energy accumulators consists in using metal hydrides in hydrogen generators in which hydrogen is generated by hydrolytically splitting off a proton from water in conjunction with the metal hydride. The chemical energy stored in the hydrogen can then be converted into electric energy in a fuel cell in a second step. Only half of the generated hydrogen originates from the metal hydride during the hydrolysis reaction; the water used for the hydrolysis process supplies the other half.
