Team Membrane Processing and Synthesis
Our goal is to develop chemically stable and highly cation- and anion-conductive polymers (ionomers) and membranes for the application in electrochemical energy conversion processes such as:
- Low-T fuel cells (H2-PEMFC, direct alcohol fuel cells such as DMFC or isopropanol/ acetone fuel cells)
- High-T fuel cells (HT-H2-PEMFC and HT-direct fuel-PEMFC)
- Electrolysers such as LT-PEMWE and HT-PEMWE, Redox-flow batteries (RFB) such as Vanadium-RFB and iron-chrome RFB
- Alkaline fuel cells and alkaline electrolysis
The types of polymers under investigation include polymers with following backbones:
- perfluorinated, partially fluorinated and nonfluorinated hydrocarbons
- nonfluorinated and partially fluorinated aromatics (polyethers, polysulfones, polyphenylenes, etc.)
From these polymers, different membrane types are made, including:
- Ionically and/or covalently cross-linked (blend) membranes
- Reinforced (blend) membranes with porous reinforcements such as electrospun fiber mats or stretched polymer foils
- Hybrid membranes with inorganic nanoparticle fillings
