Method for producing a soldered joint between a substrate and a contact element of a fuel cell unit

摘要

In order to provide a method for producing a soldered joint between a substrate for at least one electrode and a contact element of a fuel cell unit which results in the substrate being reliably soldered to the contact element but without impairing the functioning of the substrate by surplus solder material, it is proposed that the method comprise the following process steps: applying a mixture, which comprises a soldering material and a bonding agent containing an elastomer material and/or a resin, to the contact element and/or the substrate; bringing the substrate and the contact element into contact; soldering the substrate and the contact element by heating them up to a soldering temperature.
