abstract: |
In this thesis, BaZr0.7Ce0.2Y0.1O3-δ was synthesized by spark plasma sintering (SPS).
In an extensive study, SPS process parameters and their influence on the material
properties were systematically investigated to provides a better understanding of
the sintering mechanisms occurring during SPS. Additionally, the proton diffusion
and their confinement within the crystal structure were investigated by neutron spectroscopy.
As an outlook, a proof of concept with an SPS process for co-sintering of membrane-electrode-assemblies
with an application in protonic ceramic electrolysers is given.

In dieser Arbeit wurde der Protonenleiter BaZr0.7Ce0.2Y0.1O3-δ mittels des Spark Plasma
Sinterns (SPS) hergestellt. In einer umfangreichen Studie wurden die SPS Prozessparameter
und deren Auswirkungen auf die Materialeigenschaften systematisch untersucht, um einen
Beitrag zum besseren Verständnis der dem Sinterprozess zugrundeliegenden Mechanismen
zu leisten. Zusätzlich wurden die Diffusion und Einbindungen der Protonen im Kristallgitter
durch Neutronen Spektroskopie untersucht. Als Ausblick liegt ein erstes Proof-of-Concept
für einen Co-Sinterprozess von Membran-Elektroden-Einheiten vor.
