  2. 6. Modelling and Applications of the Hollow Cathode Plasma

    Author : Daniel Söderström; Hana Baránková; Ladislav Bárdos; Zoltán Donkó; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; hollow cathode; hybrid plasma; vibrational temperature; atmospheric pressure; fluid modelling; radio frequency; pulsed power; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : This thesis presents experimental and modelling research on atmospheric pressure hollow cathodes and hollow electrodes. Experiments with the hybrid hollow electrode activated discharge (H-HEAD), which is a combination of a hollow cathode and a microwave plasma source, is presented. READ MORE

  4. 7. Lithium iron phosphates as cathode materials in lithium batteries

    Author : Anna S. Andersson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; lithium batteries; cathode materials; lithium iron phosphates; magnetic properties; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : Iron-based oxides are perhaps the only realistic cathode materials for electric and electric-hybrid vehicle applications. Two types of lithium iron phosphate, LiFePO4 andR-Li3Fe2(PO4)3, have been investigated for use within the lithium/lithium-ion polymer batteryconcept. READ MORE

  5. 8. Electrochemical characterisation of porous cathodes in the polymer electrolyte fuel cell

    Author : Frédéric Jaouen; KTH; []
    Keywords : polymer electrolyte fuel cell; cathode; mass transport; porous electrode; modelling; agglomerate model; electrochemical impedance spectroscopy; current interrupt; transient techniques; non-noble catalysts;

    Abstract : Polymer electrolyte fuel cells (PEFC) convert chemicalenergy into electrical energy with higher efficiency thaninternal combustion engines. They are particularly suited fortransportation applications or portable devices owing to theirhigh power density and low operating temperature. READ MORE

  6. 9. Characterisation of materials for use in the molten carbonate fuel cell

    Author : Sara Randström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molten Carbonate Fuel Cell; Anode Current Collector; Cathode; Wet-seal; Chemical engineering; Kemiteknik;

    Abstract : Fuel cells are promising candidates for converting chemical energy into electrical energy. The Molten Carbonate Fuel Cell (MCFC) is a high temperature fuel cell that produces electrical energy from a variety of fuels containing hydrogen, hydrocarbons and carbon monoxide. READ MORE

  7. 10. New Materials for the Molten Carbonate Fuel Cell

    Author : Sara Randström; Carina Lagergren; Michel Cassir; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molten Carbonate Fuel Cell; Anode current collector; Cathode; Wet-seal; Ionic liquid; TFSI; Smältkarbonatbränslecell; Anodströmtilledare; Katod; Wet-seal; Jonvätska; TFSI; Electrochemistry; Elektrokemi;

    Abstract : Smältkarbonatbränslecellen (MCFC) är en högtemperaturbränslecell för stationära applikationer. Den har samma höga totalverkningsgrad som konventionella kraftvärme-anläggningar, men kan byggas i mindre moduler (från 250 kWe). READ MORE
