    • Oxide based two phase composite electrolyte (Ce0.9Gd0.1O2-Y2O3) was synthesized by coprecipitation method. The nanocomposite electrolyte showed the significant performance of power density 785 mW cm(-2) and higher conductivities at relatively low temperature 550 degrees C. Ionic conductivities were measured with ac impedance spectroscopy and four-probe dc method. The structural and morphological properties of the prepared electrolyte were investigated by scanning electron microscope (SEM). The thermal stability was determined with differential scanning calorimetry. The particle size that was calculated with Scherrer formula, 15-20 nm, is in a good agreement with the SEM and X-ray diffraction results. The purpose of this study is to introduce the functional nanocomposite materials for advanced fuel cell technology to meet the challenges of solid oxide fuel cell.

  • Characterization and Development of Bio-Ethanol Solid Oxide Fuel Cell
  • 2011
  • Ingår i: Journal of Fuel Cell Science and Technology. - : ASME International. - 1550-624X .- 1551-6989. ; 8:6, s. 061014-

    • Bio-ethanol based fuel cell is an energy source with a promising future. The low temperature solid oxide fuel cell fed by direct bio-ethanol is receiving considerable attention as a clean and highly efficient for the production of both electricity and high grade waste heat. The comparison of fuel cell performance with different metal-oxide based electrodes was investigated. The power densities of 584 mW cm(-2) and 514 mW cm(-2) at 520 degrees C and 570 degrees C respectively were found. The effect of electrode catalyst function, ethanol concentration on the electrical performance was investigated at different temperature ranged in between 300 degrees C-600 degrees C. The effect of deposited carbon on the electrode was investigated by energy-dispersive X-ray spectroscopy and scanning electron microscope after testing the cell with bio-ethanol.

  • Tidskriftsartikel (refereegranskat)abstract
    • A low-temperature solid oxide fuel cell system was developed to use bioethanol and glycerol as fuels directly. This system achieved a maximum power density of 215 mW cm(-2) by using glycerol at 580 degrees C and produced a great impact on sustainable energy and the environment.
