  • Characterisation of porcelain enamel coatings

    Henderson, Matthew Neil (The University of Waikato, 2002)
    This thesis focuses on the structural and compositional characterisation and corrosion performance of porcelain enamel coatings commonly used on metal substrates for protective and decorative purposes. These characteristics ...

  • Computational and empirical thermal modelling of a proposed SOFC stack housing design

    Fenton, Basil (The University of Waikato, 2004)
    Solid oxide fuel cells (SOFC) generate electricity cleanly, efficiently and quietly. There has been much effort in commercialising planar and large tubular SOFCs in the past two decades. Some research has involved modelling ...

  • Fabrication and characterisation of nickel/yttria stabilised zirconia cermet anodes for solid oxide fuel cells

    Brown, Michael Steven (The University of Waikato, 1998)
    The primary objective of this thesis was to study the Ni/YSZ system from powder preparation to electrochemical and morphological characterisation. Nickel/yttria stabilised zirconia (YSZ) cermet systems are employed as ...

  • Fabrication and characterization of micro-tubular solid oxide fuel cells

    Du, Yanhai (The University of Waikato, 2004)
    Solid oxide fuel cells (SOFC) are an energy efficient, low pollution technology for generating power and have the potential to revolutionize energy generation. Tubular and planar concepts are the most common SOFC systems. ...

  • Fabrication and properties of thin-walled SOFC electrolyte tubes

    Hatchwell, Charles Edward (The University of Waikato, 1999)
    The object of this thesis was to fabricate tubular solid oxide fuel cell (SOFC) systems operating with both high and medium temperature electrolytes, and then to study their electrical behaviour using various current ...

  • Preparation and characterisation of double doped-CeO₂ systems

    Torrens, Rob (The University of Waikato, 2002)
    Potential Solid Oxide Fuel Cell (SOFC) electrolyte materials of the composition Ce₀.₈Gd₀.₂₋ₓMₓO₂₋δ (M = Pr or Sm, x = 0.005 - 0.05) were prepared by two wet-chemical methods: oxalic acid co-precipitation and a variant of ...

  • Structural and electrical characterisation of some ABO₃ perovskites

    Phillips, Roslyn June (The University of Waikato, 1999)
    Powder X-ray diffraction and Raman spectroscopy have been used to characterise the electrolyte materials La₁₋ₓSrₓGaO₃₋δ (x = 0-0.2) and LaGa₁₋yMyO₃₋δ (y = 0-0.2, M = Cr, Mg). XRD of La₁₋ₓSrₓGaO₃₋δ (x = 0-0.2) showed the ...

  • Synthesis and properties of some doped lithium transition-metal phosphates

    Butt, Garrett Phillip (The University of Waikato, 2000)
    Four structurally related materials; LiNiPO₄, LiCoPO₄, Li₃Fe₂(PO₄)₃ and Li₃V₂(PO₄)₃, were synthesised, characterised and evaluated as potential cathode materials for lithium secondary batteries. The materials were ...
