Synthesis and properties of dense nickel and cobalt zirconia cermet anodes for solid oxide fuel cells

摘要: Porous Ni/Zirconia cermets have been traditionally used as anodes in solid oxide fuel cell configurations. They show excellent catalytic activity towards hydrogen oxidation well a number of other attributes. However, they are prone to sintering during long term operation, thus causing drop the efficiency cell. This paper describes fabrication and properties dense cermet which, we suggest, may act an intermediate layer between electrolyte porous anode possibly reduce degradation. Co Ni based systems were investigated 30 vol % Co/zirconia system could be fabricated with less than 20% porosity after being sintered at 1300°C.
