DescriptionWould you like to contribute to cutting-edge research on developing durable solid oxide electrolysis cell (SOEC) technology? DTU Energy is looking for a postdoctoral researcher to join our research activities focused on the development and long-term durability of SOEC cells, with particular emphasis on operation under technologically relevant conditions.
Electrolysis and green hydrogen play a central role in Power-to-X schemes to produce green fuels and facilitate the transition to a sustainable energy future. SOECs, which operate at high temperature (typically in the range of 600 to 850 °C), offer the highest efficiency among different electrolysis technologies. Nonetheless, SOEC technology is less mature and requires further improvements in both performance and durability to enable reliable long-term operation.
Due to the intermittency of renewable energy sources, SOEC technology must be capable of dynamic operation under varying electrical input, which is essential for effective system-level integration. In parallel, SOEC cells are inherently sensitive to impurities originating from feed gases, system components, or cell materials, which can interact with electrodes and interfaces and cause irreversible degradation. Understanding and mitigating the impact of dynamic operation and impurity-induced cell degradation is therefore critical for ensuring long-term durability and reliable operation under technologically relevant conditions.
At DTU Energy, we work to improve the durability and performance stability of SOEC cells and to gain deeper insight into degradation mechanisms under technologically relevant operating conditions. This includes experimental investigation of cell performance evolution and degradation phenomena, with particular emphasis on the effects of dynamic operation and impurity exposure. These studies address the influence of operating parameters during steady-state and dynamic operation and are carried out across relevant temperature ranges and conditions representative of real system use.
Responsibilities and qualifications
Your primary responsibilities will include:
- Investigating the durability and degradation of solid oxide electrolysis cells under technologically relevant operating conditions
- Studying the impact of dynamic operation and varying electrical input on SOEC cell performance and lifetime
- Designing and conducting electrochemical experiments to assess cell performance evolution and degradation behaviour
- Investigating impurity-induced degradation mechanisms related to feed gases, system components, or cell materials
- Analysing experimental data and correlating operating conditions with observed degradation phenomena
- Working in close collaboration with colleagues at DTU Energy and with industrial and international project partners
- Publishing research results in relevant peer-reviewed scientific journals
To succeed in this role, you should:
- Have a strong background in electrochemistry, materials science, or solid oxide cell technology
- Have hands-on experience with electrochemical testing of electrolysis or fuel cell devices
- Be highly motivated with a strong interest in SOEC durability, degradation, and long-term operation
- Possess excellent communication skills in English, both written and spoken
- Be able to work independently as well as collaboratively in a multidisciplinary research environment
In addition, it is preferable that you:
- Have experience with degradation studies of solid oxide cells or related high-temperature electrochemical devices
- Have experience with materials or microstructural characterization techniques, e.g. SEM/EDX and XRD
- Have prior knowledge of impurity effects or gas-phase contamination in electrochemical energy conversion systems
As a formal qualification, you must hold a PhD degree (or equivalent) in electrochemistry, materials science, chemical engineering, or a closely related discipline.
