Master thesis: Mechanical compatibilities of co-sintered layers in a novel low-cost solid oxide fuel cell design

At the Forschungszentrum Jülich, Institute of Energy and Climate Research, IEK-1: Materials Synthesis and Processing materials for climate-friendly technical solutions are being developed. The Solid Oxide Fuel Cell (SOFC) is a rising technology part-taking in climate-friendly energy conversions. Challenges of this technology are the relatively high manufacturing costs and compromised life-time, thus improving these are current topics of R&D investigations.

In a SOFC concept under development, the manufacturing route is simplified via a co-sinter process, and a low-cost ceramic support material is applied. The goal of this thesis work is to improve mechanical stability and adherence, and avoid processing defects of the cathode layer(s). In the thesis work, ceramic layers shall be processed in the lab by various techniques including screen printing and sintering.

Techniques to be applied:

  • Sintering behaviour with dilatometer
  • Sample deflection with white light interferometer
  • Surface quality with laser microscope
  • Cross section microstructure with light-microscope/scanning electron microscope

An understanding of the materials behaviours during processing, and improvement of mechanical compatibilities are strived for.

Qualifications: Studies in Mechanical Engineering, Materials Science or similar.

Employment: 6 Months in a Student Assistant position
