  1. 1. Drivers to and barriers against sustainable consumption : exploring the role of consumer anticipated emotions in the context of consumer adoption of alternative fuel vehicles

    Författare :Zeinab Rezvani; Johan Jansson; Maria Bengtsson; Patrick De Pelsmacker; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Consumer behavior; sustainable consumption; anticipated emotion; moral norm; attitudes; electric vehicles; alternative fuel vehicles; marketing; marknadsföring;

    Sammanfattning : With the increasing environmental problems, sustainable consumption is an important consumer behavior. Therefore, it is important to investigate further the significant drivers to and barriers against sustainable consumption, in order to increase the share of sustainable consumption and understanding of consumer behavior.

  3. 2. Electrochemical properties of alternative polymer electrolytes in fuel cells

    Författare :Annika Carlson; Rakel Lindström; Göran Lindbergh; Carina Lagergren; Mohamed Mamlouk; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel cell; anion exchange membrane; proton exchange membrane; electrode morphology; hydrogen oxidation reaction; water transport; poly phenylene oxide ; cellulose; bränslecell; anjonledande membran; protonledande membran; elektrodstruktur; vätgasoxidation; vattentransport; poly fenylenoxid ; cellulosa; Chemical Engineering; Kemiteknik;

    Sammanfattning : Fuel cells, using hydrogen as energy carrier, allow chemically‑stored energy to be utilized for many applications, including balancing the electrical grid and the propulsion of vehicles. To make the fuel cell technology more accessible and promote a sustainable energy society, this thesis focuses on alternative polymer electrolytes, as they can potentially lead to a lower cost and a more environmentally‑friendly fuel cell.

  4. 3. Development of Methanol-Reforming Catalysts for Fuel Cell Vehicles

    Författare :Johan Agrell; KTH; []
    Nyckelord :PEM fuel cells; hydrogen; methanol; reforming; oxidation; reaction pathways; carbon monoxide;

    Sammanfattning : Vehicles powered by proton exchange membrane (PEM) fuelcells are approaching commercialisation. Being inherently cleanand efficient sources of power, fuel cells constitute asustainable alternative to internal combustion engines to meetfuture low-emission legislation. LÄS MER

  5. 4. Car(ing) for our environment? : Consumer eco-innovation adoption and curtailment behaviors: The case of the alternative fuel vehicle

    Författare :Johan Jansson; Agneta Marell; Annika Nordlund; John Thøgersen; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Diffusion of innovations DOI ; value-belief-norm VBN theory; alternative fuel vehicles AFV ; eco-innovation; early adoption; curtailment behaviors; proenvironmental attitudes; innovation characteristics; Business studies; Företagsekonomi; företagsekonomi; Business Studies;

    Sammanfattning : Determinants influencing consumer eco-innovation adoption and green curtailment behaviors in a travel context are at the center of this thesis. Previous research on green consumer behavior has uncovered that internalized personal attitudinal factors such as values, beliefs, and norms are influential in determining mainly non-consumption and post-purchase behaviors.

  7. 5. Hydrogen Generation for Fuel Cells in Auxiliary Power Systems

    Författare :Marita Nilsson; Lars J. Pettersson; Gunther Kolb; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; autothermal reforming; auxiliary power unit; diesel; dimethyl ether; fuel cell; fuel-flexible reformer; hydrogen; PdZn alloy; reforming catalyst; reformer design; Rh; Chemical engineering; Kemiteknik;

    Sammanfattning : Heavy-duty trucks are in idle operation during long periods of time, providing the vehicles with electricity via the alternator at standstill. Idling trucks contribute to large amounts of emissions and high fuel consumption as a result of the low efficiency from fuel to electricity. LÄS MER
