1. 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
2. Heat recovery from low emission steel production through electrolysis and hydrogen reduction
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : The steel industry is a large emitter of carbon dioxide and uses a lot of energy. Because of an increased awareness of the detrimental effects of climate change, research in alternative ways to operate steel plants have been made. It is now possible to build plants with far less emissions by using electrolysis and hydrogen reduction. LÄS MER
3. Energy-efficient HVAC solution-sets for low-energy apartment buildings in Nordic climates - An analysis of an affordable housing project
Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljöSammanfattning : To meet the aims of the Paris climate agreement, it is necessary to reduce energy use in buildings. Efficient HVAC systems are a critical part in achieving a low delivered energy use. LÄS MER
4. Design of measurement circuits for SiC experiment : KTH student satellite MIST
Uppsats för yrkesexamina på grundnivå, KTH/Skolan för informations- och kommunikationsteknik (ICT)Sammanfattning : SiC in Space is one of the experiments on KTH’s miniature satellite, MIST. The experiment carries out tests on bipolar junction transistors of silicon and silicon carbide. This thesis describes how the characteristics of a transistor can be measured using analog circuits.
