Electrochemical cells, in particular ion exchange membrane fuel cells (IEMFCs) and electrolyzers, are central to the energy sector’s transition from fossil resources to efficient and sustainable systems for energy conversion and storage. They convert chemical energy directly into electrical energy and are widely regarded as enabling technologies for a sustainable, CO₂-free energy system.

The ion exchange membrane is the core component of these devices and largely governs performance and durability. Among proton exchange membranes (PEMs), the perfluorinated polymer Nafion remains the reference material, combining high proton conductivity with excellent chemical and mechanical stability. The development of sustainable, fluorine-free alternatives has become a major research priority. Progress in this area depends on a rigorous understanding of the properties and manufacturing routes of established membranes, which provides the basis for the targeted design and improvement of future materials.

Project aim: identify, evaluate, and optimize candidate proton exchange membrane materials for fuel cells and electrolyzers to support a sustainable, low-carbon energy transition.
