Effect of Pd-impregnation on performance, sulfur poisoning and tolerance of Ni/GDC anode of solid oxide fuel cells

Performance and carbon deposition over Pd nanoparticle catalyst promoted Ni/GDC anode of SOFCs in methane, methanol and ethanol fuels

“…Pd nanoparticles introduced by infiltration can be distinguished from Ni and GDC particles as Ni and GDC particles are typically in the range of 0.5e1.2 mm (see Fig. 11a) [42]. Infiltrated Pd nanoparticles were approximately 60 nm in diameter and distributed preferentially along the grain boundaries between GDC and/or Ni grains (Fig.…”

Biogas Catalytic Reforming Studies on Nickel‐Based Solid Oxide Fuel Cell Anodes

“…This also indicates that the carbon species adsorbed on the Ni/ScYSZ/Pd-CGO sample after CH 4 dissociation were generally more reactive than those on the Ni/ScYSZ sample. In addition, it is likely that the presence of Pd nanoparticles promoted the dissociation and surface diffusion of hydrogen, resulting in the improved catalytic activity during TPH of carbonaceous species on Ni/ScYSZ/Pd-CGO [49].The sulfur-treated catalysts did not show any CH 4 production activity in the TPH. This certainly correlates well with earlier results which showed little or no activity for CH 4 dissociation, hence there were no carbonaceous species to be hydrogenated during TPH for these sulfurtreated catalysts.…”

H2 and CH4 oxidation on Gd0.2Ce0.8O1.9 infiltrated SrMoO3–yttria-stabilized zirconia anode for solid oxide fuel cells

“…Briefly, Pt paste was painted as the counter electrode on the opposite side of the anode with the same area and the reference electrode was painted on the side of the counter electrode in two arc bars. The distance between the reference electrodes and counter electrode was 5 mm [19]. Finally, the half cells were mounted against an alumina tube and sealed by ceramic adhesive (Ceramabond 552, Aremco).…”
