      abstract     = {The production of green hydrogen for a sustainable and
                      climate-neutral society can be realized via different
                      synthesis paths. Focus of this work is the experimental
                      realization of thermal decomposition of steam in a ceramic
                      membrane reactor. The required heat is provided by solar
                      thermal energy and the oxygen produced is removed in-situ
                      through the oxygen permeable membrane. Key elements for the
                      construction of the proof-of-concept module are the oxygen
                      transport membrane material development and component
                      processing including the necessary joining technology.
                      Fe-doped SrTiO3 is selected as membrane material. The goal
                      is to develop a membrane reactor with membrane structures
                      consisting of a thin dense membrane layer, a porous support
                      layer, and catalytically active surface layers that meet all
                      requirements regarding thermo-chemical stability and
                      permeation flux. Based on the membrane properties and the
                      operating conditions, the materials for housing and sealing,
                      respectively, are selected. The reactor itself needs to be
                      designed to provide optimal gas supply to the membranes. The
                      proof of concept module design is based on a modified stack
                      of solid oxide cells. The metallic components are selected
                      to ensure chemical compatibility and thermal expansion
                      behavior with the ceramic membrane. The gas tight metal –
                      ceramic joining renders high demands on wetting, reactivity
                      and expansion behavior and do not allow pure glass ceramic
                      or Ag-based reactive solders. Instead, composite solders are
                      used for joining membrane and reactor. For this purpose, the
                      chemical und thermomechanical compatibility of the ceramic
                      membrane to the solder and metal housing, respectively, are
                      investigated. For this purpose, the interaction between
                      membrane material and glass solder is studied by sessile
                      drop test. The individual components of the reactor are
                      characterized using dilatometry. The bonding of the ceramic
                      to the metallic housing will be tested and characterized.},
