Fügen von Hochtemperatur-Brennstoffzellen
Planar solid oxide fuel cells as developed at Forschungszentrum Jülich are combined with steel interconnectors and casings to form fuel cell stacks that can be used as technical power sources. On the one hand, all the components must be joined gas-tight so that fuel and air cannot mix. On the other …

Phosphor(V)-nitride durch Hochdruck-Hochtemperatur-Synthese
1. Development and establishment of the high-pressure high-temperature synthesis as a broad approach to nitridophosphates. In this thesis for the first time a broad access to nitridophosphates was developed and therefore the basis for a systematic investigation of this class of compounds was …
