abstract = {Metal–supported membranes make an important contribution
to energy–efficient production of technical gases, such as
H$_{2}$ in the future. Furthermore, the implementation of
CCS/CCU technologies in modern fossil fired power plants
currently arouses interest. The motivation for the use of
metal substrates is a higher stability and joining
technology compared to ceramic membranes that are being
developedin parallel. Currently, the proof of concept under
real conditions of these membranesis missing. In terms of
CO$_{2}$–membranes, the stability of metals steel has to
be analysed yet. For this reason, the development of an
innovative support concept consisting of porous steel
support and ceramic interlayer from 8YSZ will be
investigated in the present work. Such a concept is suitable
for two types of membranes. First, as support for
H$_{2}$–selective Pd–Membranes, in the working
conditions such as temperatures in range between 400–550
$^{\circ}$C and pressures reaching 20 bar. The second
application is as a support for the CO$_{2}$–selective
SiO$_{2}$–membrane in the fossil fired power plants under
corrosive operating conditions. In such conditions the
supportwill be exposed to a relative humidity close to 100
\% and temperature of approximatly 70 $^{\circ}$C. The focus
of the work was the „proof of concept“ for two above
described application types. As a first step, manufacture of
substrates from Crofer22APU powders were optimised, which
consisted in developing and manufacturing of the
tape–casted supports with adjusted thickness of 1 mm. The
aim porosity of the metal substrate laid at about 30 \%. To
achieve this step, a powder with particle size <20 $\mu$m
was used. Additionally, new sintering parameters were
applied. In parallel, microstructuring experiments in IMVT,
KIT in Karlsruhe and in the IFAM, the Fraunhofer Dresden
were conducted. Furthermore, the long–term stability,
stability under flue gas conditions in the power plant of
commercial substrates Plansee (ITM 26) and GKN (316L) and in
house produced Crofer22APU was analysed. At the next stage,
the focus of the work was the development of a suitable
coating technology for metal supports. Apart to adjusting
the rheological properties of the suspension, dip–coating
parameters were examined and adapted to the support surface
and finally to coating technology. Also, the quality of
support surface in the weld seam area was consider. The weld
seam between porous support and bulk metal sheet was
processed by sandblasting [...]},
