Author's personal copy Performance and carbon deposition over Pd nanoparticle catalyst promoted Ni/GDC anode of SOFCs in methane, methanol and ethanol fuels
The electrochemical performance and carbon deposition on palladium catalyst promoted Ni/Gd0.1C0.9O1.95 (Ni/GDC) anode in methane and alcohol fuels like methanol and ethanol are investigated at open circuit potential and under dc bias using electrochemical impedance spectroscopy technique. Presence of Pd nanoparticle catalyst significantly promotes the electrocatalytic activity of Ni/GDC for the...

متن کاملIn situ fabrication of high-performance Ni-GDC-nanocube core-shell anode for low-temperature solid-oxide fuel cells
A core-shell anode consisting of nickel-gadolinium-doped-ceria (Ni-GDC) nanocubes was directly fabricated by a chemical process in a solution containing a nickel source and GDC nanocubes covered with highly reactive {001} facets. The cermet anode effectively generated a Ni metal framework even at 500 °C with the growth of the Ni spheres. Anode fabrication at such a low temperature without any s...
متن کاملEFFECT OF RHODIUM INFILTRATION ON THE MICROSTRUCTURE AND PERFORMANCE OF Ni/Ce0.8Gd0.2O2-δ CERMET ANODE FOR LOW TEMPERATURE SOLID OXIDE FUEL CELL
In order to further enhance the Ni/Ce 0.8Gd0.2O2-δ (Ni/GDC20) cermet anodic performance for low temperature solid oxide fuel cell (LT-SOFC), a study was conducted on the nanostructuring of NiO/GDC composite by only once wet-infiltration of rhodium chloride precursor. By using electrochemical impedance spectroscopy (EIS) analysis, the effect of only one drop of Rh-infiltrating solution on ...
متن کاملOperation of Ni-YSZ Anode Supported Solid Oxide Fuel Cell on Different Simulated Syngases
Ni-YSZ anode supported solid oxide fuel cells (ASCs) were tested under various simulated syngas. There was no voltage degradation of the cell operated on 41%H2-7%CH4-6%CO-11%CO2-35%H2O fuel condition for nearly 450 hours. However, the high vapor content reduced the open circuit voltage (OCV) and discharge voltage. The cells run steadily with most dry syngas until the simulated reforming tempera...
