Nickel-based (Ni/YSZ) cermets might perform serious carbon deposition using hydrocarbon fuels. Instead, many researches select Cu-based cermets to extend the application period. This study chose half replaced cermet (50%Cu–Ni in Y-doped ZrO2), and verified the effects of H2 formation and carbon deposition comparing to other two series, i.e. Ni-YSZ and Cu-YSZ. Three ingredients were homogeneously mixed and reduced, then sintered to the porosity of 54 ± 3%. The re-dox properties under various atmospheres and the permeability of made cermets have been investigated. The results showed that 50%Cu–Ni with 8YSZ performed moderate catalytic ability, low cracking rate for CH4, and good electric conductivity of 1503 S cm?1 at 650 °C. The sample is suitable for using CH4 fuel for SOFCs. ? 2020 Hydrogen Energy Publications LLC |
