PhD position - SoCool Project

At the Institute of Materials and Devices - Materials Synthesis and Manufacturing Processes (IMD-2), we work in a dynamic and international team of over one hundred materials scientists, chemists, physicists, mechanical engineers and technical staff on the development of advanced energy converters and high-performance storage systems for the energy transition. In doing so, we encompass a wide range of technologies, from oxide ceramic fuel cells to solid-state batteries, thermal barrier coatings for gas turbines, and gas separation membranes. The focus of all these technologies is on inorganic materials, which are processed as functional layers from powders or via the gas phase. For this purpose, we use scalable, industry-relevant processes that ensure rapid transfer of our research results to industry. Thus, our work contributes significantly to closing the gap between basic science and application.

Your Job

High-temperature electrolysis (HTEL) offers the highest efficiency of all known water electrolysis technologies. However, compared to low-temperature electrolysis technologies, it is still at a lower level of technological maturity. Conventional cell concepts rely on ceramic support structures, which provide numerous advantages but also present drawbacks, particularly regarding their thermo-mechanical properties. Alternatively, cell concepts based on metallic support structures exhibit excellent mechanical strength but require fundamentally different manufacturing processes. The most common support structures are perforated metal sheets or porous sintered metals. In both cases, corrosion of the support material is a key factor limiting the cell lifetime.

Within the framework of the BMFTR-funded collaborative research project SOCool, a completely novel approach to the fabrication of metal-supported solid oxide electrolysis cells (MS-SOECs) will be developed. The proposed cell concept is based on separating the mechanical function of the substrate from the transport of electronic charge carriers, thereby overcoming corrosion as the primary degradation mechanism. To realize this concept, feasibility studies on coating the innovative support structure must be carried out. The central challenge is the deposition of oxide-ceramic functional layers onto metallic components with complex microstructures. The objective is to create a multilayer coating with a graded particle size distribution, thereby establishing the prerequisites for the subsequent deposition of a dense electrolyte layer.

• Planning, conducting, and evaluating proof-of-concept experiments for coating the metallic support structure
• Pretreatment and processing of oxide-ceramic powders
• Identifying the most suitable coating technique from a range of suspension-based processing methods, such as screen printing, plasma spraying, dip coating, and electrophoretic deposition
• Developing sintering processes for coated support structures under protective or hydrogen atmospheres
• Characterization of the microstructure, phase composition and surface quality of the coated layers

Your Profile

• Successfully completed Master's degree in Materials Science, Materials Engineering, or a related field with excellent academic performance
• Strong knowledge of ceramic processing technologies, particularly suspension-based coating methods and rheology
• Solid expertise in materials science and solid-state chemistry
• Experience in powder synthesis and the fabrication of ceramic components is a strong advantage
• Excellent English language skills, both written and spoken (at least B2 level according to the CEFR

)

• In addition, your business fluent German skills round off your profil
• Enthusiasm for tackling complex scientific and engineering challenges, a strong willingness to learn, the ability to work independently, and excellent teamwork skills
