摘要: Abstract Nickel-yttria stabilized zirconia (Ni-YSZ) cermet is widely used as an anode material for solid oxide fuel cells (SOFCs). While the nickel-to-nickel chain maintains electrical conductivity path, YSZ contributes to lowering thermal expansion and inhibits nickel coarsening during high temperature (1000 °C) operation. An electroless technique employed prepare a uniform coating on powder. The process parameters this are optimized. Notably, thus prepared shows percolation at much lower content (10–20 vol.%) compared with those reported in literature.
