1. Benchmarking a 1 kW hybrid hydrogen fuel cell system
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : 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.

2. Characterisation of Ionic Liquid doped Polybenzimidazole Membranes for Application in High-Temperature Proton Exchange Membrane Fuel Cells
Master-uppsats, Lunds universitet/Kemiteknik (CI)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
3. Influence of current harmonics on the degradation of the catalyst coated membrane in PEMFC
Master-uppsats, KTH/KemiteknikSammanfattning : Sjöfarten är idag dominerad av förbränningsmotorer som är beroende av fossila drivmedel. Elektrifiering är en av huvudstrategierna för att möjliggöra fossilfri energiförsörjning inom internationell sjöfart. LÄS MER
4. Developing an innovative unit of power supply to improve the sustainability of data centers : A techno economic analysis of replacing diesel generators with fuel cells as backup power generation for data centers
Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknikSammanfattning : As the amount of data centers continues to increase, their electricity consumption and emissions are being reviewed. The current backup solution is a conventional diesel generator running on fossil fuels. As part of climate goals to reduce carbon emissions, renewable energy sources like fuel cells running on hydrogen are being considered. LÄS MER
5. System Study of the Techno-Economic Potential of a Hydrogen System : A case study of Power to Mobility and Power to Power hydrogen systems, stand-alone or integrated with a CHP
Master-uppsats, Linköpings universitet/EnergisystemSammanfattning : Green hydrogen produced with renewable electricity has gotten more attention during the last years and its different usage areas has been identified as an important part of the transition to a fossil free society. In this project the potential of a stand-alone hydrogen system and a hydrogen system integrated with a CHP, are investigated regarding technical and economic feasibility. LÄS MER
