摘要

Producing a porous metal-coated substrate, preferably an electrically conductive and/or gas-conducting substrate, comprises joining an alloy comprising a coating of metal and a base metal with a material of a substrate, and dissolving the support metal of the alloy associated with the material of the substrate. An independent claim is also included for a porous substrate, preferably ceramic substrate, which is electrically conductive and/or gas-conducting.
