Gas Diffusion Layers with Patterned Wettability
During PEFC’s operation the reactant gas is fed to the cell through the gas diffusion layer (GDL) and through the same material the product water is removed. Water accumulation near the catalyst can block the gas access causing an increase of the mass transport losses. On the other hand, PEFC’s work with a solid electrolyte membrane that needs to be hydrated in order to be proton conductive. In order to obtain the maximum performance PEFC’s require a well-balanced water management.
Battery Electrodes and Cells
The primary goal is the development of a safe, environmentally benign, and cost effective electrochemical energy storage system with significantly improved specific energy. The research work focuses equally on the scientific background essential for the development of new technologies and on the analysis of ageing and safety relevant aspects of current industrial batteries. The investigated systems include both lithium-ion and post-lithium-ion batteries.
