  1. 1. Assessment of a solid oxide fuel cell powering a full electric aircraft subsystem architecture

    Master-uppsats, KTH/Flygdynamik

    Författare :Antoine-Amaury Guillerm; [2020]
    Nyckelord :;

    Sammanfattning : This paper presents the work from a Master thesisat Bauhaus Luftfahrt (Munich, Germany) about subsystemdesign and analysis for electric commercial aircraft, particularlythe assessment of a Solid Oxide Fuel Cell (SOFC) powering a fullelectric subsystem architecture. The different components of theSOFC system architecture are modelled and assessed with theOpenMDAO framework. LÄS MER

  3. 2. Vidareutveckling av katalysatorer för pre-reforming i bränslecellssystem

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Alexander Schönauer; [2020]
    Nyckelord :catalysis; pre-reforming; fuel cells; SOFC; DMSOFC; heterogeneous catalysts; propane reforming; chemical engineering; kemiteknik; Technology and Engineering;

    Sammanfattning : Heterogeneous catalysts to be used in a pre-reformer for fuel cell systems have been investigated based on active phase composition and catalyst preparation methods for granulate and monolithic catalysts. The catalysts were manufactured using θ – aluminum oxide as carrier, promoted with lanthanum and cerium, with active phases consisting of noble metal X and nickel in various concentrations. LÄS MER

    Master-uppsats, KTH/Materialvetenskap

    Författare :Line Larby; [2020]
    Nyckelord :SOC; SOFC; interconnect; Cr evaporation; Cu-Fe coatings; spinel; SOFC; SOC; interkonnektor; bipolär platta; Cr-förångning; Cu-Fe-beläggningar; spinell;

    Sammanfattning : As current environmental challenges are gaining increased attention, development of clean energy solutions is becoming one of the essential strategies to keep within the boundaries of established environmental policies. Solid oxide cell (SOC) technology can provide clean energy conversion and storage when hydrogen is the energy carrier. LÄS MER

  5. 4. Improved interconnect materials for next-generation Solid Oxide Fuel Cells

    Master-uppsats, KTH/Materialvetenskap

    Författare :Pablo Collantes; [2019]
    Nyckelord :Solid Oxide Fuel Cells; High Temperature Corrosion; Self-healing; Interconnects;

    Sammanfattning : Solid Oxide Fuel Cells (SOFC) are attractive candidates in the search for cleaner and energy efficient production due to their numerous advantages such as fuel flexibility, modularity and exceptional efficiencies when combined heat and power is harnessed. A key element in its design are the interconnects which are mainly manufactured from custom ferritic stainless steels to carry the electricity between two adjacent cells. LÄS MER

  7. 5. Phase field modelling of LLZO/LCO cathode-electrolyte interfaces in solid state batteries

    Master-uppsats, Uppsala universitet/Strukturkemi

    Författare :Michele Riva; [2018]
    Nyckelord :LLZO; LCO; phase; field; phase-field; phasefield; solid; state; solid-state; solidstate; battery; batteries; sintering; model; modelling;

    Sammanfattning : This work describes two phase field models for the simulation of the interface evolution between a LiCoO2 cathode (LCO) and a Li7La3Zr2O12 solid electrolyte (LLZO) in a Li-metal/LLZO/LCO battery during high temperature sintering. In these conditions atomic species tend to diffuse into the opposing material, creating an intermediate layer of mixed composition which resists the movement of lithium ions. LÄS MER
