Abstract: The invention relates to a metal matrix material made of a hydrogen-permeable metal 1 and a chemically stable metal 2 that is also hydrogen permeable, said matrix material having a structure comprised of a plurality of centers made of the metal 2 surrounded by the metal 1. The invention further relates to a method for the production of said matrix material, having the following steps: a. optionally pretreating the metal 1 and/or 2 b. coating metal 1 with a metal 2 to form a composite metal powder c. pressing the composite metal powder into the metal matrix material according to the invention in the form of a pressed body d. optionally deforming the pressed body thus obtained to form a molded body. The metal matrix material has a greater mechanical stability as compared to a conventionally coated metal film by virtue of a more homogeneous stress distribution during the change in volume of the metal phases as a result of hydrogen absorption and thermal expansion.
