  2. 1. Fuel Cells and Biogas

    Author : Lars Hedström; Per Alvfors; Peter Lund; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air bleed; biogas; carbon dioxide; carbon monoxide; current distribution; dilution; efficiency; energy conversion; energy systems; experimental; fuel cell; fuel cell systems; PEFC; poisoning; reformate; SOFC; Chemical energy engineering; Kemisk energiteknik;

    Abstract : This thesis concerns biogas-operated fuel cells. Fuel cell technology may contribute to more efficient energy use, reduce emissions and also perhaps revolutionize current energy systems. The technology is, however, still immature and has not yet been implemented as dominant in any application or niche market. READ MORE

  4. 2. Functional nanocomposites for advanced fuel cell technology and polygeneration

    Author : Rizwan Raza; Bin Zhu; Torsten Fransson; Mahmut D. MAT; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polygeneration; advanced fuel cell; functional materials; ceria-carbonate nanocomposites; multi-fuelled; electrolyte free fuel cell; SRA - Energy; SRA - Energi;

    Abstract : In recent decades, the use of fossil fuels has increased exponentially with a corresponding sharp increase in the pollution of the environment. The need for clean and sustainable technologies for the generation of power with reduced or zero environment impact has become critical. READ MORE

  5. 3. 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

  6. 4. Modelling and experimental investigation of the porous nickel anode in the molten carbonate fuel cell

    Author : Mari Sparr; Göran Lindbergh; Kas Hemmes; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; molten carbonate fuel cell; MCFC; mechanism; cell modelling; porous electrode; Kemiteknik; Chemical engineering; Kemiteknik;

    Abstract : The thesis is focussed on the performance of the fuel cell and the design of the cell for operation with natural gas and renewable fuels, e.g. biogas or gasified biomass. The performance is one of the important issues for the development and commercialisation of fuel cell stacks. READ MORE

  7. 5. Microbial Fuel cells, applications and biofilm characterization

    Author : Adolf Krige; Paul Christakopoulos; Sebastià Puig; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MFC; Microbial fuel cell; Raman microscopy; BES; Geobacter sulfurreducens; Biokemisk processteknik; Biochemical Process Engineering;

    Abstract : Since the 1900’s it has been known that microorganisms are capable of generating electrical power through extracellular electron transfer by converting the energy found organic compounds (Potter, 1911). Microbial fuel cells (MFCs) has garnered more attention recently, and have shown promise in several applications, including wastewater treatment (Yakar et al. READ MORE
