  2. 1. 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

  4. 2. Applications for Molten Carbonate Fuel Cells

    Author : Ivan Rexed; Göran Lindbergh; Carina Lagergren; Michel Cassir; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molten Carbonate Fuel Cell MCFC ; poisoning; electrolyte degradation; SO2; Electrochemical Impedance Spectroscopy EIS ; CO2 separation; button cell set-up; reversible molten carbonate fuel cell; high temperature electrolysis.; Chemical Engineering; Kemiteknik;

    Abstract : Molten Carbonate Fuel cells are high temperature fuel cells suitable for distributed generation and combined heat and power, and are today being installed on commercial basis in sizes from 100kW to several MW. Novel applications for MCFC which have attracted interest lately are MCFC used for CO2 separation from combustion flue gas, and high temperature electrolysis with reversible fuel cells. READ MORE

    Abstract : Polymer electrolyte fuel cells occupy a key position in implementing the hydrogen economy on a global scale. However, assessments of cost, availability and sustainability of materials currently used to manufacture state-of-the-art fuel cell stacks have given cause for concern. READ MORE

  6. 4. Pulsed Electric Field Treatment of Plant Tissue

    Author : Mustafa Fincan; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bimodal Fickian diffusion model; Food and drink technology; Livsmedelsteknik; generalized Maxwell model; onion Neutral Red; visualization; red beetroot; potato; epidermis; plant tissue; electroporation; Cell permeabilization; Pulsed electric field; PEF;

    Abstract : A pulsed electric field (PEF) is a newly emerged non-thermal food processing technology which has characteristic effects on the cell membrane. PEF processing involves subjecting food to short, repeated pulses of a high electric field between an anode and a cathode. READ MORE

  7. 5. Interfaces in Organic Solar Cells

    Author : Xian'e Li; Mats Fahlman; Xianjie Liu; Artem Bakulin; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Organic semiconductors (OSs), the promising candidates for the next generation electronic devices, have shown their advantages of light weight, flexibility, semi-transparency, tunable optical gaps, and energy levels, in the development history of over 70 years. OSs have been widely used in versatile applications such as organic light-emitting diodes, organic field-effect transistors, organic photodetectors, and organic solar cells (OSCs) which are mainly studied in this thesis.
