ABSTRACT:
A storage body composed of a silicon material, such as amorphous or finely crystalline silicon, is charged, with hydrogen, for example by contact with a hydrogen-containing atmosphere under positive pressure while at a temperature below about 100.degree. C. Such a body absorbs a relatively large amount of hydrogen and the so-absorbed hydrogen can be discharged by heating the body to temperatures above about 50.degree. C. The storage body may comprise a relatively thin silicon layer on a substrate, such as a steel, quartz glass or the like plate and may be overcoated with a catalytically-active metal layer, such as a palladium layer.
