      abstract     = {Membrane-based oxy-combustion is a promising technology for
                      energy efficient combustion of carbon-containing fuels with
                      the simultaneous opportunity to capture CO2 from the
                      resulting exhaust gas. However, oxy-combustion conditions
                      result in special demands on the design of the ceramic
                      membrane components due to the high pressure and temperature
                      applied. Therefore, we have developed a planar membrane
                      design for 4-end operation using asymmetric membranes of
                      La0.6Sr0.4Co0.2Fe0.8O3−δ. FEM and CFD simulations have
                      been performed in order to develop an internal channel
                      structure that allows withstanding pressures of 5 bar on
                      the feed side while achieving the desired O2 concentrations
                      of $27\%$ in the sweep gas, i.e. CO2, and an oxygen recovery
                      rate from the feed gas of $86\%$ at the same time.Due to the
                      symmetric design of the membrane components, they are
                      scalable and adaptable in size. This design has been
                      realized in a process chain from powder to the final
                      component consisting of thin 20 µm Membrane layer,
                      support with $38\%$ porosity, an inner channelled
                      architecture and a thin (3–5 µm) porous activation
                      layer. Particular emphasis was laid on scalable
                      manufacturing processes in order to ensure transferability
                      to industrial scale. The process chain is also applicable to
                      other membrane materials suitable for any application of
                      interest. Finally, the reproducible processing was
                      successfully demonstrated by the fabrication of membrane
                      components in lengths of 100 mm and widths of 70 mm.},
