Abstract

Kontinuierlich hergestellte Materialverbunde mit gleichmäßiger Fertigungsqualität enthaltend (a) mindestens eine Schicht, die ionenleitendes und/oder elktronenleitendes Material enthält, (b) mindestens eine Schicht, die eines oder mehrere weitere Funktionsmaterialien enthält, welche sich in innigem Kontakt zu einer elektronenleitenden und/oder ionenleitenden Schicht befinden, wobei die relative Schwankungsbreite mindestens eine Verbundeigenschaft Δx/x, ausgewählt aus der Gruppe: Dicke des Materialverbundes, Gleichstromleitfähigkeit, Wechselstromkapazität und Oberflächenrauhigkeit, < 25 % ist. Insbesondere weisen die Materialverbunde, gegebenenfalls nach Überführung in eine Membran-Elektroden-Einheit, in einer Brennstoffzelle am Leistungsmaximum eine Schwankungsbreite der elektrischen Leistung ΔP0 auf, die klein ist gegenüber der elektrischen Leistung P0 und bevorzugt ΔP0/P0 < 25 % ist. Weiterhin betrifft die Anmeldung ein Verfahren zur kontinuierlichen Herstellung von Materialverbunden mit gleichbleibender Fertigungsqualität, wobei mindestens ein flächiges Gebilde, das ionenleitendes oder elektronenleitendes Material enthält, kontinuierlich geführt und mit mindestens einem weiteren Gebilde oder Material kontaktiert und verbunden wird, das ein weiteres Funktionsmaterial enthält.
