Beschreibung
Zusammenfassung:	The invention relates to a panel-shaped porous carrier substrate (1) for a metal-assisted electrochemical functional device, which is produced by powder metallurgy and comprises a central region (2) and an edge region (3). On one surface of said central region, a layer stack comprising electrochemically-active layers can be arranged on a side of the carrier substrate that faces the cell. A surface section (4) of the edge region (3) has a carrier substrate material melt phase on the cell-facing side of the carrier substrate, and at least some sections of a region (5) lying beneath the surface section (4) with the melt phase have a higher porosity than said surface section (4) with the melt phase arranged above.
