Zunaechst wird kurz die Funktion einer Membranbrennstoffzelle, einer Metallhydridzelle und Streifenmembranzelle beschrieben. Da die bisher verwendeten polymeren perfluorierten Membranen die Eigenschaft besitzen, unloeslich und unschmelzbar zu sein, wurde ein polymerer Festkoerperelektrolyt auf der Basis sulfonierter Poly(m-phenylen-co-p-phenylen)e entwickelt, der zusaetzlich im viskosen Zustand verarbeitbar ist, d.h. in bestimmten organischen Loesemitteln loeslich ist. (MM)The functioning of a diaphragm fuel cell, a metal hybride cell and strip diaphragm cells is first briefly described. As the previously used polymer perfluoridated diaphragms have the properties of being insoluble and non-melting, a polymer solid electrolyte based on sulph...
