Master Thesis: Influence of N2 crossover on the purity of H2 in a PEM water electrolyzer
The Electrocatalytic Interface Engineering department, led by Prof. Thiele at the Helmholtz-Institute Erlangen-Nürnberg for Renewable Energy (HI ERN), focuses on different technical interfaces present within electrochemical devices, such as fuel cells and water electrolyzers.
A major advantage of Proton Exchange Membrane (PEM) electrolyzers is the high purity of hydrogen produced. Depending on the application scenario lower purity is acceptable, which opens alternative operating strategies and concepts for PEM electrolysis systems. In this work, the influence of nitrogen on the purity of the hydrogen produced in a PEM electrolyzer will be examined.
Your main tasks include:
- literature research on use cases of H2 based on N2 contamination
- processing electrodes into membrane electrode assemblies (MEAs)
- electrochemical testing of MEAs for water electrolysis
- investigating gas crossover characteristics via mass spectrometry
- evaluating, interpreting and comparing experimental results to literature
- establishing a cost estimation based on the investigated system
We are looking for motivated students...
- from engineering, physics or related
- who enjoy working in international teams (English language skills required).
- with experience and interest working independently in a laboratory environment.
- with basic understanding of electrochemistry and transport phenomena.
We offer...
an excellent, international and interdisciplinary working environment with leading experts in the field of electrochemical research. The master thesis contributes to the development of climate-friendly solutions for hydrogen production, exploring novel concepts to accelerate and drive forward the energy transition.
