Conducting research for a changing society: This is what drives us at Forschungszentrum Jülich. As a member of the Helmholtz Association, we aim to tackle the grand societal challenges of our time and conduct research into the possibilities of a digitized society, a climate-friendly energy system, and a resource-efficient economy. Work together with around 7,400 employees in one of Europe’s biggest research centers and help us to shape change!
Polymer electrolyte fuel cells (PEMFCs) are an intriguing technology for clean power production instead of fossil fuel-based generation and, hence, an integral part of the energy transition. Ionic liquids, especially protic phosphonium-based ionic liquids, emerge as promising candidates as electrolytes for the IT-PEMFC due to their high ionic conductivity at elevated temperatures and anhydrous conditions. In this master thesis, the influence of water content and temperature on the electrochemical behavior of the PPILs will be investigated using electrochemical and physicochemical methods in the Physicochemical Laboratory of the Institute of Energy Technologies - Electrochemical Process Engineering (IET-4). Here, you can find more information about our mission and projects: https://www.fz-juelich.de/de/iet/iet-4/forschung/pcl.

Master Thesis – Electrochemical Investigation of Ionic Liquids for IT-PEMFC
Activities and responsibilities
The centerpiece of PEMFCs is the polymer electrolyte membrane (PEM), which should provide sufficient ionic conductivity and mechanical stability. However, the state-of-the-art PEMs Nafion and H3PO4 / PBI either require sufficient hydration for good ion conductivity or lead to catalyst poisoning. This makes it necessary to look for alternatives with good ion conduction, even in the anhydrous state. Ionic liquids, especially protic phosphonium-based ionic liquids (PPILs), are promising candidates due to their high ionic conductivity at elevated temperatures and under anhydrous conditions. With this background, we need you to electrochemically characterize PPILs under different conditions. Your tasks in detail will be:
- Determination of electrochemical and physicochemical properties of the ionic liquids with various methods: conductivity via Electrochemical Impedance Spectroscopy (EIS), Walden plot for the determination of the proton conduction mechanism, electrochemical stability via Linear Sweep Voltammetry (LSV), Oxygen Solubility and Oxygen Diffusion Coefficient via Chronoamperometry (CA), thermal stability via Thermal Gravimetric Analysis (TGA), and Infrared Spectroscopy (ATR-IR)
- Electrode preparation via polishing
- Close collaboration with internal and external cooperation partners
- Detailed evaluation and procession of measurement data
Qualification profile
- Enrolled in a master’s program in chemistry, physics, materials science, or a related discipline
- Experience in practical lab work
- Theoretical knowledge of electrochemistry and electrochemical techniques is advantageous
- Strong analytical skills and a willingness to engage in experimental research
- A proactive and independent working attitude
- Good written and oral communication skills in English and/or German
