Postdoctoral Position in Multiphysics Modelling of Bubble Transport and Electrochemical Processes in Alkaline Electrolysers

Postdoctoral Position in Multiphysics Modelling of Bubble Transport and Electrochemical Processes in Alkaline Electrolysers

SDU - University of Southern Denmark

Sønderborg, Denmark

About the Position

The position is funded through a collaborative research and innovation project involving SDU, DTU, and Stiesdal Hydrogen, and aims to reduce the CAPEX of green hydrogen production by developing a next-generation bipolar electrode cassette for alkaline electrolysers. One focus will be on geometry-driven bubble management.

As a postdoctoral researcher, you will join the SDU Energy Systems Group at the Centre for Industrial Mechanics (CIM) and play a key role in developing advanced simulation tools and validating simulations with experimental results. Your work will combine multiphase CFD modelling, current distribution modelling, and collaboration with experimentalists. The objective is to create predictive models that guide cassette design, identify optimal operating conditions, and reduce the need for extensive physical prototyping.

Working closely with researchers at SDU and DTU, as well as engineers at Stiesdal Hydrogen, you will contribute to the development of next-generation hydrogen production technology with clear industrial impact and support its path towards large-scale implementation.

Your Role

• Develop and apply simulation methods for multiphase transport and current distribution in electrolyzers
• Investigate bubble-buoyancy-driven internal electrolyte circulation
• Quantify transport processes affecting mass transfer and electrochemical performance
• Integrate computational and experimental results to advance mechanistic understanding and predictive modelling
• Collaborate with academic and industrial partners
• Mentor and supervise students (PhD, MSc, BSc) on related research questions
• Publish research results in peer-reviewed journals and present at international conferences
• Contribute to research funding applications and assist with teaching activities as relevant

Your Profile

• PhD in engineering, computational science, physics or related discipline
• Background in computational fluid dynamics (CFD)
• Experience in multiphase flow and/or electrochemical transport modelling
• Experience with numerical simulation software such as ANSYS, COMSOL, or OpenFOAM
• Programming skills in Python, C++, or equivalent languages
• Strong teamwork, communication, and independent research skills
• Proficient in English (spoken and written)
