Deposition of Thin Film Electrolyte by Pulsed Laser Deposition (PLD) for micro-SOFC Development
Krogstad, Hedda Nordby (Master thesis, 2012)Optimalization of PLD deposition of YSZ for micr-SOFC electrolyte applications by varying deposition pressure and target-substrate distance.Substrate used was Si-based chips and wafers (large area PLD), and the substrate ... -
Gas Switching Reforming (GSR) for syngas production with integrated CO2 capture using iron-based oxygen carriers
Zaabout, Abdelghafour; Dahl, Paul Inge; Ugwu, Ambrose; Tolchard, Julian R; Cloete, Schalk Willem Petrus; Amini, Shahriar (Journal article; Peer reviewed, 2019)The process behavior of a Gas Switching Reforming (GSR) reactor was studied using three different iron-based oxygen carrier materials: Iron-oxide on Alumina, Iron-Nickel oxide on Alumina and Iron-Ceria on Alumina. It was ... -
Gas Switching Reforming for syngas production with iron-based oxygen carrier-the performance under pressurized conditions
Ugwu, Ambrose; Zaabout, Abdelghafour; Tolchard, Julian R; Dahl, Paul Inge; Amini, Shahriar (Journal article; Peer reviewed, 2019)A four-stage Gas Switching Reforming for syngas production with integrated CO2 capture using an iron-based oxygen carrier was investigated in this study. The oxygen carrier was first reduced using dry methane, where high ... -
Synthesis and Characterization of Hydrogen Transport Membranes
Roaas, Lasse Valland (Master thesis, 2012)Hydrogen transport membranes have gained interest from industry as an alternative to pressure swing adsorption or cryogenic distillation, and are aimed to reduce cost, equipment size, energy consumption and waste generation. ... -
Synthesis of Li-ion battery cathode materials by flame spray pyrolysis
Lobintsev, Vyacheslav (Master thesis, 2016)Li-ion batteries (LIBs) constitute the leading technology within power sources. They are used in hybrid and pure electric vehicles as well as portable electronics and at the present time surpassed other types of battery ... -
Tailored Porosities of the Cathode Layer for Improved Polymer Electrolyte Fuel Cell Performance
Zlotorowicz, Agnieszka; Jayasayee, Kaushik; Dahl, Paul Inge; Thomassen, Magnus Skinlo; Kjelstrup, Signe (Journal article; Peer reviewed, 2015)We show experimentally for the fi rst time that the introduction of macro-pores in the nanoporous catalyst layer of a polymer electrolyte membrane fuel cell can improve its performance. We have ach- ieved a Pt utilization ... -
The Relationship between Hydroxyl Content and Viscosity of Fused Silica for the Czochralski Process
Cheung, Tsz Chung (Master thesis, 2019)Kvartsglass av høy kvalitet brukes i digler til produksjon av monokrystallinske silisium "ingots" i solcellein- dustrien. Monokrystallinske wafere blir laget i slike digler ved Czochralski(CZ)-prosessen. Digelen kan ikke ...
