Abstract

The invention provides a supported metal membrane which contains a metal membrane on a support surface of a porous membrane support. The supported metal membrane is obtainable by applying the metal membrane to the support surface of the membrane support, wherein the pores in the membrane support are sealed, at least in the region of the support surface, prior to applying the metal membrane and are opened by removing the auxiliary substance only after applying the metal membrane.
