1. 1. Benchmarking a 1 kW hybrid hydrogen fuel cell system

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Jonathan Envall; [2023]
   Nyckelord :PEMFC; fuel cell; UAV; hybrid; Technology and Engineering;

   Sammanfattning : Unmanned Aerial Vehicles (UAV's) offer great versatility in the tasks that they may perform and they are today used in many sectors. The H24LEO project, administered by the Lund University School of Aviation, aims to develop and demonstrate a hybrid proton-exchange membrane fuel cell-powered UAV to aid in search and rescue operations performed by the Swedish Maritime Administration, and reduce the greenhouse gas emissions compared to similar work performed by helicopters.

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

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Adam Jacobsson Trönndal; [2023]
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

4. 3. Potentiella användningsområden för spillvärme från vätgasproduktion

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Jesper Öhman; [2023]
   Nyckelord :Energiåtervinning; Energilagring; MBBR; Spillvärme; Vätgas;

   Sammanfattning : Vätgas tar en allt större plats i den gröna omställningen inom gruv- och stålindustrin vilket initiativtagande projekt såsom Hybrit och H2 Green Steel bevisat. Vätgas framställs ofta från fossila bränslen vilket genererar koldioxidutsläpp men om produktionen istället sker med elektricitet från förnybara energikällor anses tillverkningen förnybar. LÄS MER

5. 4. Hydrogen Production from Offshore Wind Power in Sweden

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

   Författare :Linnéa Hulting; Nellie Eriksson; [2023]
   Nyckelord :Hydrogen; Electrolysis; Offshore wind power; LCOH; PEM; SOE; AEC; Technology and Engineering;

   Sammanfattning : The versatile energy carrier hydrogen has the potential to reach otherwise hard-to-abate sectors and is of importance for the energy transition and the full decarbonisation of the energy systems. In the meantime, the offshore wind power is predicted to increase where large amounts of electricity can be produced. LÄS MER

7. 5. Investigating Yttrium Ruthenate Pyrochlore as an Anodic Electrocatalyst in Proton Exchange Membrane Water Electrolysis

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Kneev Sharma; [2023]
   Nyckelord :;

   Sammanfattning : As the energy transition progresses, the demand for green storage solutions is ever-increasing. Hydrogen storage is receiving increased interest and support due to its promising sustainability and flexibility. Proton-exchange, or polymer electrolyte, membrane (PEM) electrolyzers are a key technology supporting hydrogen storage systems. LÄS MER
