Electrolysis and power-to-X are becoming key energy technologies in the green transition, as they will be essential for us in replacing fossil fuels. The solid oxide electrolysis technology is a very promising technology because of the high efficiency and hereby lower operational cost. However, while the performance of solid oxide electrolysis cells is the most efficient of all electrolysis technologies, the lifetime of the technology can still be improved.

Several degradation mechanisms have been identified, and while some have a physical background, e.g. migration of nickel in the fuel electrode and detachment of the oxygen electrode, others mechanisms relate to chemical stability or build up of impurities in the cell. These problems should thus be tackled with multiple approaches, i.e. development of new materials, but also understanding the impact of these impurities in the system and the rate that they degrade the cell with.

This PhD project will focus on the latter while collaborating with others in a project group who will be looking into improvements of the materials as well. The project will thus be on both cell testing under various conditions while also modelling this for a deep understanding of the degradation phenomena.

The work will be done in collaboration with industry, using both state of the art cells, but also newly developed cells in the laboratory.

Responsibilities and qualifications
You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.

You will be working with a team of technicians, postdocs and other students to achieve the goals in the project. The work will be both characterization and on modelling of the electro-chemical performance of solid oxide electrolysis cells.

You should thus preferably be:

  • Experienced with lab-work and characterization
  • Experienced in multi-physics modelling, preferably of electro-chemical systems
  • Be a good team-worker - be happy to share thoughts and receive feedback from others
  • Have a background in technical sciences or engineering, i.e. physics, chemistry, energy technology or other relevant background

Approval and Enrolment
The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide.

Assessment
The assessment of the applicants will be made by Senior Researcher Henrik Lund Frandsen, Professor Anne Hauch and Professor Rasmus Bjørk.

Application procedure
Your complete online application must be submitted no later than 3 December 2021 (Danish time).

We will evaluate applications and call selected applicants for interview after deadline.

Applications must be submitted as one PDF file containing all materials to be given consideration. To apply, please open the link "Apply online", fill out the online application form, and attach all your materials in English in one PDF file. The file must include:

  • A letter motivating the application (cover letter)
  • Curriculum vitae
  • Grade transcripts and BSc/MSc diploma
  • Excel sheet with translation of grades to the Danish grading system (see guidelines and Excel spreadsheet here – in the right hand column)

Incomplete applications will not be considered. Applications received after the deadline will not be considered.

You may apply prior to obtaining your master's degree but cannot begin before having received it.

All interested candidates irrespective of age, gender, disability, race, religion or ethnic background are encouraged to apply.
