Open positions


The junior research group „Electrochemical Energy Systems“ works on fuel cells, batteries and electrolyzers. The group is dedicated to integrating latest material developments into state-of-the-art electrochemical energy systems.

To date, the most widespread water-splitting technology is the proton-exchange membrane (PEM) water electrolysis due to its efficiency, long-term stability and operation at high current densities. While PEM electrolyzers are commercially available, their costs are still high due to the acidic environment, fluorine-based membranes and noble metal catalysts. Therefore anion-exchange membrane (AEM) based electrolyzers have attracted attention, since they combine the advantageous properties of PEMWEs with the promise of significant cost reduction.

For this purpose, we are looking for a motivated student to help develop membranes/electrodes for AEM electrolysis. You will be working in close collaboration with our PhD-students, post-docs and engineers, mostly in the laboratory measuring and analyzing fabricated devices using X-Ray fluorescence spectrometry.

Your profile
  • Communication and team-work skills are essential
  • You are interested to work in the field of energy storage and sustainable technologies
  • You work in a target-oriented and structured manner
  • Beneficial: experience in lab work, spectroscopy, and/or elec-trochemistry
The position
  • Excellent working conditions in the young and interdisciplinary “Electrochemical Energy Systems” (EES) group
  • Flexible working time with 4-15 hours per week
  • Starting date: flexible
  • Working language: English or German

The use of hydrogen fuel cells in vehicles and trucks is one possibility to reduce the CO2 emissions emitted by the transport sector. Since the catalyst is one of the main cost drivers in the system, this area has become the focus of research in the past years. The junior research group „Electrochemical Energy Systems“ at the Institute of Microsystems Engineering and the Hahn-Schickard Institute in Freiburg investigates state-of-the-art hydrogen technologies and develops novel fuel cell concepts in cooperation with industry partners.

Your task

The core of a hydrogen fuel cell is the membrane electrode assembly (MEA), in which the catalyst is embedded in the electrodes. Your task would be to develop a colloidal deposition via laser ablation of one/different catalysts for an electrochemical energy system (fuel cell, CO2 electrolysis, etc.).

Your profile
  • You are communicative and have a high team-spirit
  • You are interested in novel materials for energy storage and renewable energies
  • You can work in a concentrated, focused and structured way
  • You are experienced with practical work and enjoy working in the lab
The position
  • We offer excellent working conditions in an interdisciplinary research group with a pleasant collegial working atmosphere
  • Modern infrastructure for material characterization
  • The working language is English or German
  • Earliest starting date: November 2022
  • Prior to the thesis, we would appreciate 3 months of HiWi occupation within our group

Fuel cells play a key role in reducing CO2 emissions in the transport sector by converting the chemical energy of hydrogen into electrical energy to power the vehicle. However, the efficiency of state-of-the-art fuel cells is mainly limited by transport processes in the electrodes. This project aims to improve the efficiency and make fuel cells more competitive. For this purpose, the current understanding of the phenomena limiting the performance and durability will be investigated.

Your task

You will be working in a national project with the aim to develop fuel cells for aviation. You will characterize the latest fluorine free polymers and develop membrane electrode assemblies (MEAs) with them. You will investigate the material properties and correlate them with their performance in operating fuel cells. Thus, the work ranges from material analysis (DMA, TGA, SEM, EDX,…) and fabricating of own fuel cell MEAs to electrochemical measurements (fuel cell tests, electrochemical impedance spectroscopy…).

Your profile
  • Excellent communication skills and team spirit are necessary
  • You are interested in the development of novel materials for sustainable aviation
  • You work target-oriented and structured
  • You enjoy working with measurement methods and are interested in the physical relationships
The position


  • We offer excellent working conditions in the interdisciplinary “electrochemical energy systems” EES group with a friendly atmosphere
  • Cutting edge equipment for fuel cells and material characterization
  • The typical duration of a PhD is planned for three years (80% TV-L 13)
  • The working language is English or German
  • Earliest possible start: November 2022
  • Family-friendly, flexible working hours
