Abstract

Carbon deposition on Pr0.42Sr0.6Co0.2Fe0.7Nb0.1O3−σ (PSCFN) and Ni–yttria stabilized zirconia (Ni–YSZ) due to thermal CH4 decomposition under dry CH4 has been investigated by using temperature-programmed reaction techniques. The morphologies of carbon formed are characterized by using scanning electron microscopy (SEM). It is found that carbon nanofibers are obviously formed on PSCFN while spherical carbons are formed on Ni–YSZ. Analyses of the results on CH4 temperature-programmed decomposition and O2 temperature-programmed oxidation reveal that the high catalytic activity for the cracking of CH4 and the easier oxidation of the generated carbon species on PSCFN could be the main reason why PSCFN shows high performance and good stability in direct CH4 fuel solid oxide fuel cells (SOFCs).
