Foil material for the storage of hydrogen

摘要

A foil material for the storage of hydrogen in materials capable of bearing hydrogen, i.e. a hydrogen storageable material. Through the intermediary of a heat-conductive bond between a metal having hydrogen storage capability and a substrate, which is adapted for the absorption and conducting off of the reaction heat produced during hydrogen exchange, and on which the hydrogen storageable metal is applied as a storage layer, there is afforded a rapid heat exchange during the loading and unloading of the storage layer. Employed for this purpose is the heat capacity of the substrate. The material for the substrate and the volume of the latter is so selected that the reaction to heat is exchangeable with the substrate of the storage layer without the need for ancillary heat exchangers; in effect, can be taken up by or given up from the substrate. The storage layer has its exposed surface covered with a protective layer which acts in a corrosion-inhibiting manner and which is permeable to hydrogen.
