Description

The Department of Energy Conversion and Storage, Technical University of Denmark (DTU), invites applications for a PhD scholarship in the advanced characterization of high temperature proton conducting electrochemical cells and stacks. The activities are aimed at identifying the mechanisms that limit the performance and lifetime of cells and stacks via advanced electrochemical and microstructural characterisation and explore strategies for enhancing performance and durability. Transforming our society to rely only on sustainable energy sources is a formidable engineering challenge. Key to success will be the development of cost competitive and reliable methods to produce hydrogen via electrolysis of water/steam driven by green electricity. Hydrogen can be used as a fuel in itself or serve as a reactant to produce fuels like methanol, kerosene or even ammonia. Large scale deployment of such electrolysis units is highly needed to enable displacement of fossil fuels. Steam electrolysis can be realized with cells constructed from proton conducting oxides. Such cells can be used, not only as an electrolyser or fuel cells, but can also work as electrochemical pumps for hydrogen separation and hence holds merit in terms of multi-functionality. Compared with solid oxide cells using oxygen ion conductors, proton conducting cells are less mature. Understanding the key factors that affect the performance of these cells and under various operation conditions is highly desired for further progressing the technology. Responsibilities and qualifications You will work on electrochemical and microstructural characterisation of proton conducting cells and stacks. Electrochemical characteristic techniques such as impedance spectroscopy and tracking of IV-characteristics will be applied. Tests will be conducted in different operation modes such as fuel cell-, electrolyser- or hydrogen separation-mode or even involving an additional down-stream synthesis step to ammonia. The methodologies must be further developed to analyse the off-gasses of the experiment and for cyclic operation. Key tasks will be * Development/upgrading single cell/stack test setups for advanced electrochemical characterisation. * Establishing test protocols for accelerated testing. * Test of proton conducting cells under different operation conditions and analysing the degradation associated to each operate parameters * Microstructural characterisation of the tested cells and correlating changes to electrochemical results. You will work in a team of colleagues working on electrochemical characterization and also in project-groups with colleagues specialised in component manufacture. As part of the PhD education, you will follow courses and assist in teaching activities, and: * You are expected to spend at least 3 months at a foreign research institution * You will disseminate your work in international peer reviewed journals and at professional conferences. Candidates 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. We favour candidates with a degree in materials science, solid state chemistry, electronic engineering or similar. Experience with one or more of the following areas is an advantage. * Fuel cells and electrolysis * Electronic / power electronics * Materials characterization * Electrochemistry Moreover, the successful candidate * is innovative and able to work in cross-disciplinary teams * has good communication skills in English, both written and spoken * is able to work independently and take responsibility for the progress and quality of projects. Approval and Enrolment The scholarship for the PhD degree is subject to academic approval, and the candidate 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 DTU's rules for the PhD education [https://www.dtu.dk/english/Education/PhD/Rules]. Assessment Your application will be assessed by Professor Peter Vang Hendriksen and associate Professor Xiufu Sun. We offer DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility. Salary and appointment terms The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed upon with the relevant union. The period of employment is 3 years. The workplace is DTU Lyngby Campus. The employment is expected to start 1 August 2026, or according to mutual agreement.

Furthermore, you have the option of joining our monthly free seminar “PhD relocation to Denmark and startup “Zoom” seminar [https://www.dtu.dk/english/about/job-and-career/moving-to-denmark/before-arrival/phd-relocation-to-denmark]” for all questions regarding the practical matters of moving to Denmark and working as a PhD at DTU. Application procedure Your complete online application must be submitted no later than 8 June 2026 (23:59 Danish time). Applications must be submitted as one PDF file containing all materials to be given consideration. To apply, please open the link "Apply now", 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 (in English) including official description of grading scale You may apply prior to obtaining your master's degree but cannot begin before having received it. Applications received after the deadline will not be considered. All interested candidates irrespective of age, gender, disability, race, religion or ethnic background are encouraged to apply. As DTU works with research in critical technology, which is subject to special rules for security and export control, open-source background checks may be conducted on qualified candidates for the position.
