  1. 1. High Temperature Co-Electrolysis Model for Sector Coupling : Thermodynamic and Detailed Models of Solid Oxide Electrolysis Cells and Systems

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : FAISAL SEDEQI; [2020]
    Keywords : ;

    Abstract : The increased development of intermittent renewable energy supplies not only demands robust storage technology, but also alternative means to produce materials in ways to avoid fossil fuel consumption and make use of the increasing electricity supply. Power to gas (PtG) through solid oxide cell (SOC) co-electrolysis reactors provide an attractive manner to overcome both challenges. READ MORE

  3. 2. EBL Patterned ITO Contacts for Single Nanowire Devices

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Markus Snellman; [2018]
    Keywords : Physics and Astronomy;

    Abstract : Nanowires have attracted interest as fundamental building blocks for electronic and optoelectronic devices as well as for fundamental research. Photonic studies of single nanowire devices typically involve patterning of metal electrodes for electronic access, yet plasmonic ef- fects between the metal contacts and the light source may perturb experimental measurements.

  4. 3. Design of Resonant Filters for AC Current Magnification : Heating of Li-ion Batteries by Using AC Currents

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Nikolina Djekanovic; [2018]
    Keywords : Current control; injection of alternating current; internal heat dissipation; LCL filter; Lithium-ion batteries; power efficiency; resonance phenomenon;

    Abstract : Using alternating current in order to heat batteries at sub-zero temperatures is a method,which is investigated in-depth by an increasing number of study groups. The thesis considersthe resonance phenomenon with the intention to use alternating current amplificationand battery’s impedance in order to induce power dissipation inside the battery, and in thisway increase its temperature.

  5. 4. Dynamic modeling of a solid oxide fuel cell system in Modelica

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Daniel Andersson; Erik Åberg; [2010]
    Keywords : Solid oxide fuel cell Modelica simulation; Technology and Engineering;

    Abstract : In this study a dynamic model of a solid oxide fuel cell system has been developed. The work has been conducted in cooperation with Modelon AB using the Modelica language and the Dymola modeling and simulation tool. Modelica is an equation based, object oriented modeling language, which promotes flexibility and reuse of code. READ MORE
