Electrochemical Energy Conversion
The Electrochemical Energy Conversion Section is focused on the development and in-depth understanding of materials, processes and devices for the conversion of renewable energy into electricity or chemical energy carriers. Especially in the context of a sustainable energy system utilizing hydrogen as an energy carrier and its electrochemical energy conversion is of particular importance.
Fuel Cell Car developed by Belenos Clean Power Holding and Paul Scherrer Institut at the coast of Lake Neuchâtel.
In this topical context our goal is the in-depth understanding of technologies like Polymer Electrolyte Fuel Cells (PEFC), Polymer Electrolyte Electrolyzer Cells (PEEC) for water electrolysis and processes like the co-electrolysis of CO2 and water, respectively.
The R&D strategy involves activities on four pathways: i) system, stack and cell engineering; ii) membrane development based on PSI’s own radiation-grafting technology and the development of cell components; iii) research in electrocatalysis and the reaction kinetics of the important reactions (e.g., the oxygen electrode reactions) for improved understanding of intrinsically limiting factors; and iv) the development and application of advanced in-situ diagnostic tools on stack, cell and component levels including analyses of the electrode-electrolyte interface.
In addition, we are working on new materials for advanced electrochemical double layer capacitors (EDLC), which includes the application of ionic liquids or graphene-type carbons for high energy EDLCs.
