Characterization and Development of Bio-Ethanol Solid Oxide Fuel Cell

Abstract

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 °C and 570 °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 °C−600 °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.
