Abstract

original image

Ein wichtiger Abbaumechanismus von Perowskit-Membranen steht in Verbindung mit der betriebsbedingten Ausscheidung von Schwefelspuren, die das Permeationsverhalten bei niedriger Temperatur drastisch beeinflussen. Eine einfache, aber bemerkenswert effektive Methode wird vorgestellt, die es ermöglicht, den Permeationsfluss in diesen Membranen bei niedrigen Temperaturen zu stabilisieren (siehe Bild).
