Eligibility/Qualification:
- Master’s degree (or equivalent) in Materials Science, Chemical Engineering, Chemistry, Physics, or a related field.
- Strong background in electrochemistry, materials characterization, or catalysis. Experience with fuel cells or related electrochemical energy conversion systems is a plus.
- Hands-on experience in experimental laboratory work, specifically with thin-film deposition techniques (e.g., ALD, CVD, sputtering) is highly desirable, or strong motivation to acquire this expertise.
- Familiarity with characterization techniques such as electron microscopy (TEM/SEM), XRD, or surface area analysis (BET) is an advantage.
- Experience with electrochemical characterization methods (e.g., cyclic voltammetry, polarization curves) is beneficial.
- Analytical mindset with the ability to interpret complex experimental data and translate it into actionable insights.
- Genuine interest in interdisciplinary research at the interface of materials science, electrochemistry, and sustainable energy technologies.
- Strong communication skills and the ability to collaborate effectively within an interdisciplinary, international team.
- Independent, structured, and hands-on working style, excellent team spirit.
- Good written and spoken English; German language skills are a plus, but not required.
- Prior experience with academic writing and a track record of (or strong interest in) publishing in peer-reviewed journals.
Job Description:
- Fabricate and evaluate catalyst-ionomer composite electrodes, systematically varying ionomer-to-carbon ratios and catalyst architectures.
- Integrate the developed electrodes into fuel cell devices.
- Conduct electrochemical characterization (e.g., fuel cell measurements, cyclic voltammetry, ECSA measurements) to assess catalyst and electrode performance in combination with hydrocarbon (HC) ionomers.
- Develop over- and under-coatings to improve the stability and activity of the catalysts.
- Investigate the interplay between catalyst structure, Pt distribution, and HC ionomer properties to identify performance-limiting mechanisms.
- Collaborate with project partners to develop new carbon supports and HC ionomer materials.
- Contribute to the development of improved electrode recipes and fabrication processes.
- Document results and contribute to peer-reviewed publications and conference presentations.
