2. 1. On Gas Contaminants, and Bipolar Plates in Proton Exchange Membrane Fuel Cells

   Author : Yasna Acevedo Gomez; Carina Lagergren; Göran Lindbergh; Rakel Wreland Lindström; Qinfeng Li; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PEM fuel cell; contaminants; ammonia; nitrogen dioxide; degradation; recovery; bipolar plates; electroplating; Ni-Mo; Ni-Mo-P; internal contact resistance; PEM bränslecell; föroreningar; ammoniak; kvävedioxid; degradering; återhämtning; bipolära plattor; elektroplätering; Ni-Mo; Ni-Mo-P; interna kontaktmotståndet; Chemical Engineering; Kemiteknik;

   Abstract : The proton exchange membrane (PEM) fuel cell is an electrochemical device that converts chemical energy into electrical energy through two electrocatalytic reactions. The most common catalyst used is platinum on carbon (Pt/C), which has shown the best performance in the fuel cell until now. READ MORE

4. 2. Hybrid materials for lithium-ion batteries

   Author : Cesario Ajpi Condori; Göran Lindbergh; Anders Lundblad; Andrew Kentaro Inge; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hybrid battery materials; conducting polymer composite; metal organic compounds; lithium-ion batteries.; Kemi; Chemistry; Chemical Engineering; Kemiteknik;

   Abstract : The Lithium‐ion batteries are the most important power source for electronic devices as electronics, storage and the different electric vehicles. The research and development of new materials for different applications has increased, especially in the development of materials with better electrochemical properties (Specific capacity, rate capability, high energy density and cyclability).

6. 4. Interactions between battery and power electronics in an electric vehicle drivetrain

   Author : Alexander Bessman; Göran Lindbergh; Pontus Svens; Oskar Wallmark; Torbjörn Thiringer; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The electric machine and power electronics in electric and hybrid electric vehicles inevitably cause AC harmonics on the vehicle's DC-link. These harmonics can be partially filtered out by large capacitors, which today are overdimensioned in order to protect the vehicle's battery pack. READ MORE

7. 5. The anode and the electrolyte in the MCFC

   Author : Andreas Bodén; Göran Lindbergh; Carina Lagergren; Takao Watanabe; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; composite electrolytes; electrode kinetics; nickel solubility; porous electrode; reformate; water-gas shift reaction; electrolyte; electrolyte distribution; hydrogen oxidation reaction; ion segregation; mass transport; mathematical modelling; MCFC; molten carbonate fuel cell; Chemical engineering; Kemiteknik;

   Abstract : A goal of the Swedish government is to increase the usage of renewable fuels and biomass-based fuels. Fuel cells, and especially the MCFC, are useful for these types of fuels. The Swedish market may benefit from the MCFC in two ways: increased efficiency of the biofuels and also utilisation of produced heat in district heating. READ MORE
