      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 [...]},
