Method for producing an electrochemical cell element, electrochemical cell element, electrochemical cell device

Abstract

The present invention relates to a method (100) for manufacturing an electrochemical battery element (10), the electrochemical battery element comprising an electrochemical battery (14), particularly an electrolytic battery (14), and an interconnect (24), wherein the electrolytic battery (14) has at least three functional layers (26) and a metal battery substrate (22), wherein the interconnect (24) has a protrusion (16). The interconnect (24) is connected to the battery substrate (22) by a plurality of micro-soldering connectors (34), each micro-soldering connector (34) being disposed on a protrusion (16). The invention relates to a method (100) for producing an electrochemical cell element (10) comprising an electrochemical cell (14), in particular an electrolysis cell (14), and an interconnector (24), wherein the electrolysis cell (14) has at least three functional layers (26) and a metallic cell substrate (22), wherein the interconnector (24) has elevations (16). It is proposed for the interconnector (24) to be connected to the cell substrate (22) by a plurality of microweld connections (34), each microweld connection (34) being arranged on an elevation (16).
