   Sammanfattning : Although current trends in global warming are of great concern, energy demand is still increasing, resulting in increasing pollutant emissions. To address this issue, we need reliable renewable energy sources, lowered pollutant emissions, and efficient and profitable processes for energy conversion. LÄS MER

3. 12. Thin-Film Electrocatalysts for Polymer Electrolyte Fuel Cells - Activity, Durability and Proton Conduction

   Författare :Björn Wickman; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nafion; thin film evaporation; PEMFC; platinum; titanium oxide; cathode; fuel cell; oxygen reduction reaction; electrocatalyst; proton conduction; model systems;

   Sammanfattning : The polymer electrolyte membrane fuel cell (PEMFC) is a potential technology for future energy conversion in sustainable energy systems. By using hydrogen from renewable energy sources and oxygen from the air, the fuel cell produces electricity with water as the only exhaust. LÄS MER

4. 13. Co-Evolution of Technology, Markets and Institutions - the Case of Fuel Cells and Hydrogen Technology in Europe

   Författare :Stian Nygaard; CIRCLE; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Innovation; fuel cells; market development; hydrogen; industrial dynamics; business development; innovation policy; Europe;

   Sammanfattning : The birth, growth and maturity of industries, sectors and technologies have spurred the curiosity of researchers as well as managers and policy makers for a long time. Intriguingly, the emergence of a new industry is a complex process including many different actors and with a high level of uncertainty related to technology, institutions and markets facing the actors involved.

5. 14. Combined solar and pellet heating systems for single-family houses : How to achieve decreased electricity usage, increased system efficiency and increased solar gains

   Författare :Tomas Persson; Per Lundqvist; Simon Furbo; Högskolan Dalarna; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pellet; pelleteldning; kamin; panna; solvärmesystem; varmvattenberedning; systemutformning; småhus; elbesparing; verkningsgrad; emissioner; rökgasförluster; skorstensförlust; diskmaskin; tvättmaskin; Thermal energy engineering;

   Sammanfattning : In Sweden, there are about 0.5 million single-family houses that are heated by electricity alone, and rising electricity costs force the conversion to other heating sources such as heat pumps and wood pellet heating systems. Pellet heating systems for single-family houses are currently a strongly growing market. LÄS MER

7. 15. Semiconductor-ionic Materials for Low Temperature Solid Oxide Fuel Cells

   Författare :Muhammad Afzal; Andrew R. Martin; Peter Lund; Hab. Armelle Ringuede; KTH; []
   Nyckelord :Semiconductor-ionic materials; electrolyte-layer free fuel cell; low temperature solid oxide fuel cell; fuel to electricity conversion; Schottky junction; theoretical and experimental curves; Halvledar-joniska material; elektrolytskikt-fri bränslecell; lågtemperatur fastoxidbränslecell; bränsle till elomvandling; Schottky junction; teoretiska och experimentella kurvor; Energy Technology; Energiteknik;

   Sammanfattning : Solid oxide fuel cell (SOFC) is considered as an attractive candidate for energy conversion within the fuel cell (FC) family due to several advantages including environment friendly, use of non-noble materials and fuel flexibility. However, due to high working temperatures, conventional SOFC faces many challenges relating to high operational and capital costs besides the limited selection of the FC materials and their compatibility issues.
