AbstractThis thesis investigates the electrolyte distribution in porous electrodes of high-temperature polymer electrolyte membrane fuel cells (HT-PEMFCs) and vanadium redox flow batteries (VRFBs). Overall, the electrolyte distribution directly impacts performance and lifetime of these systems and hence system efficiency. The analysis of both systems allows to highlight the influence of various parameters on the electrolyte distribution in porous electrodes and helps to develop an approach for optimization.dc.description.abstract
AbstractIn dieser Dissertation wurde die Electrolytverteilung in porösen Electroden von Hochtemperatur-Polymerelektrolytmembran Brennstoffzellen und Vanadium Redox Flow Batterien untersucht. Die Electrolytverteilung hat einen direkten Einfluss auf die Leistungsfähigkeit und Lebensdauer dieser beiden System und damit auch auf die Effizienz. Die Analyse fokussiert sich auf den Einfluss verschiedener Parameter auf die Elektrolytverteilung in porösen Elektroden und hilft, einen Optimierungsansatz zu entwickeln.dc.description.abstract
