    Keywords : Nafion; thin film evaporation; model catalyst; electrocatalyst; acetic acid oxidation; oxygen reduction; colloidal lithography; PEMFC; screening; Pt; formaldehyde oxidation; methanol oxidation; nanofabrication; CO oxidation; polymer electrolyte; TiOx;

    Abstract : A long term challenge for society is to develop sustainable energy systems to reduce the dependence on fossil fuels and to decrease air pollution. This requires new alternatives regarding the supply of energy and increased efficiency of the future energy systems. Fuel cell technology is one such possible alternative. READ MORE

  6. 4. Photosynthetic water oxidation : the function of two extrinsic proteins

    Author : Tatiana Shutova; Göran Samuelsson; Stenbjörn Styring; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photosystem II; Psb0; Cah3; water oxidation; Plant physiology; Växtfysiologi;

    Abstract : The solar energy accumulated by photosynthesis over billions of years is the sole source of energy available on Earth. Photosystem II (PSII) uses the sunlight to split water, an energetically unfavorable reaction where electrons and protons are extracted from water and oxygen is released as a by-product. READ MORE

  7. 5. Electrochemical Reactions in Polymer Electrolyte Fuel Cells

    Author : Maria Wesselmark; Svein Sunde; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel cell; model electrodes; oxygen reduction; methanol oxidation; formic acid oxidation; hydrogen oxidation; CO oxidation; degradation; tungsten oxide; carbon support; Bränslecell; modellelektroder; syrgasreduktion; metanoloxidation; myrsyraoxidation; vätgasoxidation; CO oxidation; degradering; wolfram oxid; kolsupport; Chemical engineering; Kemiteknik;

    Abstract : The polymer electrolyte fuel cell converts the chemical energy in a fuel, e.g. hydrogen or methanol, and oxygen into electrical energy. The high efficiency and the possibility to use fuel from renewable sources make them attractive as energy converters in future sustainable energy systems. READ MORE
