About this position
This PhD project at Aalborg University is based in AAU Energy, within the research group Hydrogen and Electro Fuels and the section for Thermal Engineering. The project sits at the intersection of chemical and electrochemical reactor engineering and is centered on proton exchange membrane (PEM) water electrolysis.
The doctoral researcher will study PEM electrolysis cells experimentally and through detailed modelling. The work includes designing and conducting single-cell experiments, characterising electrochemical performance under different operating conditions, and developing mechanistic models that capture transport, kinetics and degradation phenomena. A key part of the project is to examine how electrolyser performance changes when conventional materials are partly replaced with recycled ionomers and iridium, comparing stability and degradation patterns and using those results to deepen understanding of the underlying electrochemical mechanisms.
Alongside the core experimental and modelling work, the project also includes techno-economic assessment and life cycle assessment of PEM electrolysis systems. This lets the PhD student evaluate how material choices, operating strategies and system design influence costs and environmental impacts across the full life cycle.
The project is embedded in the CYCLOPEM, EDSOES and CAPEX projects, giving access to advanced experimental facilities and collaboration with academic and industrial partners. The research environment at AAU Energy is international and interdisciplinary, with daily group activities, seminars, joint publications and opportunities to present results at conferences and workshops. The department also offers advanced laboratory and workshop facilities within a broader clean-energy research environment.
The PhD student will also contribute to teaching activities in courses on chemical and electrochemical reactors and take part in the wider activities of the research group.
