• Additive manufacturing of an electrode cooling system

  Additive Fertigung einer Elektrodenkühlung

  27.08.2025

  Masterthesis, Bachelorthesis

  Electrochemical systems play a vital role in the development of efficient, eco-friendly energy storage and conversion methods. Additive manufacturing is increasingly recognized as a promising approach for electrode production in these systems. In electrochemical systems, heat is often produced due to inefficient energy conversion or resistance losses. This affects the efficiency of the overall process. A possible solution is the creation of a cooling system that dissipates heat directly through channels within the electrode. This cooling system could be used in applications such as fuel cells.

• Process simulation of the iron energy storage cycle with AspenPlus

  Energiespeicher für erneuerbaren Strom: Prozesssimulation des Eisenkreislaufs zur Energiespeicherung mit AspenPlus

  21.08.2025

  Masterthesis

  Large-scale energy storage is a critical challenge for achieving a green economy. The metal energy cycle presents a promising approach by allowing cyclic combustion and reduction processes without CO2 emissions. Among potential energy carriers, iron powder stands out due to its favorable combustion characteristics. To accurately compare the iron cycle and its different iron reduction methods to competing energy storages, a simulative process analysis is needed.

• Microfluidic PEM electrolyzer for hydrogen production

  Mikrofluidischer PEM-Elektrolyseur für die Wasserstofferzeugung

  14.07.2025

  Masterthesis, Bachelorthesis

  Hydrogen has been recognized as one of the most promising pathways for decarbonizing the energy sector, while providing the required energy demands in an environmentally friendly manner. Proton exchange membrane (PEM) electrolyzers are a key technology for hydrogen production. However, for a large-scale adoption, enhancements in long-term operations are important. The durability of a PEM cell is negatively influenced by leaching of catalyst ions. To tackle this problem, it is of critical importance to understand the movement of metal ions near the catalyst layer and through the membrane. Novel experimental methods, such as fluorescence microscopy, can be used to investigate the electrochemical reaction and the transport of ions in a microfluidic PEM electrolyzer.
