| 520 | _ | _ | |a 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. |
