Chair of Technical Electrochemistry

Prof. Dr. Hubert Gasteiger

In the field of Power-to-X, the Chair of Technical Electrochemistry is performing research on solutions for proton exchange membrane (PEM) water electrolyzers. By using renewable energies it is possible to produce green hydrogen via PEM water electrolysis. The research at the Chair of Technical Electrochemistry focusses on the design of membrane electrode assemblies (MEAs) and of porous transport layers (PTLs) which are central components in PEM water electrolyzers. Topics include fundamental aspects (e.g. understanding of reaction mechanisms of novel catalyst materials) as well as applied research (e.g. reduction of catalyst loadings in MEAs, evaluation of MEA lifetime).

Research at the Chair of Technical Electrochemistry regarding the usage of PtX products focusses on proton exchange membrane (PEM) fuel cells to generate electrical energy. Topics include catalyst synthesis and catalyst layer design based on platinum group metals (PGM) as well as the development and characterization of PGM-free catalyst materials. Furthermore, transport processes in catalyst and gas diffusion layers are investigated and optimized. Performance and durability testing with in situ and ex situ diagnostics is performed, to gain a deeper understanding of degradation mechanisms.

Pushing PEM Fuel Cells to Their Full Potential - Materials Development and Porous Layer Design Guided by Advanced Diagnostic
The Sinergia project aims at creating a better fundamental understanding of mass transport limitations on the cathode side of a PEM fuel cell. The cathode reaction requires protons being transported to the active site via a proton conductive ionomer phase and oxygen being supplied through the gas phase, mediated by the gas diffusion and microporous layer. To improve the mass transport in these components, we investigate ionomer-support-interactions and identify the characteristic structural parameters of the microporous layer using electrochemical and spectroscopic techniques.

Development of pore-optimized catalysts and catalyst layers for high-performance polymer electrolyte membrane fuel cells
Fuel cell evaluation of pore-optimized catalyst layers

To achieve the required energy transition in Germany, the focus areas in the field of innovative energy technology, which were set within the frame of the 7th energy research program's call for proposals "Innovationen für die Energiewende", have to be adhered to. Especially in the field of fuel cell research, a higher efficiency of polymer electrolyte membrane fuel cells (PEMFCs) should be achieved, while simultaneously reducing the use of active catalyst material and therefore minimizing costs.
These requirements should be met within the frame of this joint project by investigating and using pore-optimized catalysts for future high performance PEMFCs. The required long-term stability is extensively investigated by studies at the Chair of Technical Electrochemistry. The results of the project aim for a contribution to leverage  hydrogen technologies like fuel cells and strengthen the German expertise in manufacturing core components for PEMFCs.

Next Generation AutomotIve membrane electrode Assemblies
The goal of GAIA is the development of membrane electrode assemblies (MEAs) for proton exchange membrane fuel cells (PEMFCs) with improved power density at high current densities as well as increased durability. In accordance with the defined cost reduction of the PEMFCs, the developed MEAs are also tested at elevated operation temperatures.

Funding:  The GAIA project has received funding from the Fuel Cells and Hydrogen 2 Joint Undertaking under grant agreement No 826097. This Joint Undertaking receives support from the European Union’s Horizon 2020 research and innovation programm, Hydrogen Europe and Hydrogen Europe Research.
