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

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

    Abstract : 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.

  4. 2. Durability evaluation of PEM fuel cell components

    Author : Live Mølmen; Peter Leisner; Lars Fast; Frode Seland; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Proton exchange membrane fuel cell; bipolar plate; corrosion; interfacial contact resistance; electrocatalysis; Polymermembranbränsleceller; bipolära plattor; korrosion; kontaktresistans; katalys;

    Abstract : Proton exchange membrane fuel cells (PEMFCs) are used to convert hydrogen and oxygen to electricity, heat, and water. There are no greenhouse gas emissions, given that the hydrogen is produced from renewable sources, such as water electrolysis from wind, hydro or solar energy. READ MORE

  5. 3. Plasmonic Nanostructures for Optical Absorption Engineering and Hydrogen Sensing

    Author : Carl Wadell; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photocatalysis; metal hydride; alloy nanoparticles; palladium; absorption engineering; plasmon enhanced chemistry; nanoplasmonic sensing; nanoparticle size effects; localized surface plasmon resonance; hydrogen sensing;

    Abstract : Nanoplasmonics concerns the interactions between light and metal nanoparticles. In this thesis nanoplasmonics is used in two different ways: i) to control and enhance light absorption, and ii) for optical hydrogen sensing. READ MORE

  6. 4. Catalytic reactions and hydrogen sensing with Pt- and Pd-MIS devices

    Author : Anette Salomonsson; Linköpings universitet; []
    Keywords : ;

    Abstract : The hydrogen sensitivity of catalytic metal-insulator-semiconductor (MIS) devices has been known for almost 30 years [1,2]. With Pd or Pt as the metal gate the electronic properties of the device are influenced by hydrogen and the device can thereby be used as a gas sensor for hydrogen and hydrogen containing gases.

  7. 5. Intrinsically Proton-Conducting Benzimidazole Units Tethered to Different Polymer Chain Architectures

    Author : Christian Persson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; biopolymers; Kemiteknik och kemisk teknologi; Polymer technology; Chemical technology and engineering; Materiallära; materialteknik; Material technology; Makromolekylär kemi; Macromolecular chemistry; proton-exchange membrane fuel cell; structure diffusion; thiol-ene reaction; segmental mobility; high temperature; benzimidazole; block copolymers; polymer electrolyte; anhydrous proton conductivity;

    Abstract : Proton transport is a fundamental process that can be found in many systems in nature, as well as in technical devices, such as fuel cells, electrochromic devices and various types of sensors. Fuel cell technology is considered as environmentally friendly because fuel cells are not limited by the Carnot cycle, and efficiently converts chemical energy into electrical energy which can be used for powering cars, laptops, buildings etc. READ MORE
