3. 2. Characterisation of Ionic Liquid doped Polybenzimidazole Membranes for Application in High-Temperature Proton Exchange Membrane Fuel Cells

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Adam Jacobsson Trönndal; [2023]
   Keywords : Fuel cells; Phosphoric acid; Polybenzimidazole; PA-PBI; Ionic liquid; IL; High temperature proton exchange membrane fuel cell; HT-PEMFC; Electrochemical impedance spectroscopy; EIS; IL-PBI; Chemical engineering; Technology and Engineering;

   Abstract : In this study four membranes were tested and evaluated against each other for use in high-temperature proton exchange membrane fuel cell (HT-PEMFC) applications. A phosphoric acid (PA) doped polybenzimidazole (PBI) membrane, was used as a reference as the current state-of-the-art. READ MORE

4. 3. Plume-Spacecraft Interaction Analysis : Study on the Plume Effects of Hall-Effect Thrusters (HET) and High-Efficiency Multistage Plasma Thrusters (HEMPT).

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Josep Sentís Garzón; [2023]
   Keywords : Electric propulsion; Plasma plume; Plasma physics; SPIS; OpenPlume EP; Modelling; Charge-Exchange Collisions; Elektrisk framdrivning; Plasma plym; Plasmafysik; SPIS; OpenPlume EP; Modellering; Laddningsväxlingskollisioner;

   Abstract : Plume-spacecraft interactions play an important role in the performance and integrity of spacecraft during their missions in space. The study encompasses a thruster’s plume simulation and its impact on spacecraft geometries to understand and predict the effects and consequences of the impingement on spacecraft surfaces, such as erosion, contamination, forces, and torques.
