PhD Position – High-Temperature Electrolysis – from stack design to operational optimization

Your Job

Help us shape the energy transition! As part of your doctoral studies, you will support the development of innovative stack designs, operating strategies and measurement methods for power‑to‑X systems using high‑temperature electrolysis (SOEC). The developed methods will serve to optimise the operation of SOCs for hydrogen production both technically and economically and improve tolerance against impurities. In doing so, you will make a direct contribution to national and European climate targets.

• Planning, implementation and evaluation of long‑term and transient tests of stacks with solid oxide cells (SOC) in electrolysis mode
• Electrochemical characterisation of cells during stack operation using direct and alternating current‑based techniques (e.g. characteristic curves / cyclic voltammetry, amperometry, electrochemical impedance spectroscopy)
• Experimental investigation of the material compatibility of interconnector steels, protective coatings and cell materials with adapted glass‑ceramic joining materials, with a focus on interactions during the joining process and under operating conditions
• Optimisation of experiments, measurement methods and measurement technology, including test facilities with regard to the research and project objectives
• Collaboration in the analysis of operated SOC stacks through disassembly and post‑test characterisation to identify material interactions and damage mechanisms for linking with operating data
• Collaboration and networking with other departments at the research centre (cell development, stack construction, system and component development, microscopy, spectroscopy)
• Presentation of findings at specialist conferences, publication in leading journals and active exchange with industry and research partners

Your Profile

• Completed master degree in chemistry, electrochemistry, technical chemistry, chemical engineering or a comparable field (e.g. engineering related to process engineering or chemistry)
• Good knowledge of electrochemistry, materials science and/or process engineering systems is an advantage
• Knowledge of relevant programming languages for data processing/evaluation, especially Python / Matplotlib, is an advantage
• Independent, structured and responsible way of working, commitment, high degree of teamwork skills, and enjoyment of cooperative collaboration
• Interest in familiarising yourself with new technologies and topics
• Good knowledge of German and English
