Abstract

Um ein Verfahren zum Herstellen einer Lötverbindung zwischen einem Substrat für mindestens eine Elektrode und einem Kontaktelement einer Brennstoffzelleneinheit zu schaffen, durch welches eine zuverlässige Verlötung des Substrats mit dem Kontaktelement erzielt wird, ohne daß die Funktion des Substrats durch überschüssiges Lotmaterial beeinträchtigt wird, wird vorgeschlagen, daß das Verfahren die folgenden Verfahrensschritte umfaßt: DOLLAR A - Aufbringen eines Gemisches, das ein Lotmaterial und ein Bindemittel, welches ein Elastomermaterial und/oder ein Harz enthält, umfaßt, auf das Kontaktelement und/oder das Substrat; DOLLAR A - Inkontaktbringen des Substrats und des Kontaktelements; DOLLAR A - Verlöten des Substrats und des Kontaktelements durch Erwärmung auf eine Löttemperatur.
