520 _ _ |a 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 [...]
