Effect of nickel nano-particle sintering on methane reforming activity of Ni-CGO cermet anodes for internal steam reforming SOFCs

▶ ISRM over Ni-CGO cermet catalysts prepared by single-step GNP was investigated. ▶ Steam lean conditions showed a continuous and moderate reforming activity. ▶ Steam rich conditions showed high reforming activity which decreased with time. ▶ TEM/EDS analysis evidenced nickel nano-particle sintering effect.
