      abstract     = {Satisfyingthe ever increasing global demand for energy and
                      material goods whileachieving the ambitious CO 2 emissions
                      targets of the EU for 2030 on climate changerequires the
                      utilization of renewable resources e.g., wind, solar) in the
                      fuels andchemical industries. The project AMAZING (Additive
                      Manufacturing for Zero emissionInnovative Green Chemistry)
                      directly addresses this by replacing large scale
                      hightemperature cracking processes e.g., steam cracking)
                      with el ectrically driven thermocatalytic activation of
                      alkanes to produce chemical building blocks allowing
                      significantreduction in the CO 2 emissions associated with
                      energy intensive cracking reactions.Thecore of the cell
                      assembly is a ceramic membrane made from mixed proton
                      andelectron conducting La 6 x WO 12 δ To increase the
                      electronic conductivity of the materialMo as doping element
                      is used to form La 6 x W 0.8 Mo 0.2 O 12 δ (LWO Mo20). The
                      powder isin house produced and the particle size, specific
                      surface area and chemical compositionis determined before
                      the ceramic layers are formed. Therefore, three
                      differentfabrication techniques are used in this work. The
                      first one is sequential tape casting andlamination to
                      fabricate an asymmetric structure of a dense m embrane layer
                      (thickness25 µm) and a porous support (thickness 500 µm).
                      Furthermore 3D printingtechniques are implemented to achieve
                      defined support structures. Firstly, acombination of tape
                      casting and material extrusion ( is introduced, where
                      thesupport structure is printed directly on a tape cast
                      membrane layer. This techniqueallows a good membrane quality
                      but suffers during the co firing of the final
                      layers.Secondly, a pure 3D printing approach is introduced,
                      which utilizes 3D screen print ing.With this technique both,
                      membrane and support layer, are formed subsequently in
                      onemachine allowing good membrane quality and precise
                      support structures.Afterco firing all membrane components
                      undergo a quality testing procedure, whichincludes He
                      leakage determination and white light topography. The next
                      step is thejoining of the ceramic membrane into a metal
                      frame to form a membrane module, whichcan easily be built in
                      a test reactor and quickly exchanged for multiple tests. The
                      joiningprocedure takes place in a furnace at 850 °C
                      applying load on the sealing area. Glasssealant is used to
                      connect the ceramic and metal part. After joining, another
                      He leakagetest is performed to assure the joining quality.
                      With this procedure large amounts oflab scale membrane
                      modules can be fabricated for further performance tests.},
