title = "Multilayered SOFC anode structure with electroless Ni-YSZ for enhancement of cell performance",
abstract = "High performance SOFC is fabricated using multilayer anode support with graded porosity. The graded anode fulfills the requirement of proper fuel oxidation at anode, effective electrochemical reaction at anode/electrolyte interface, thermal compatibility among cell components and long term stability. In such multilayer anode, conventional cermet (40 vol\% Ni) helps in proper fuel diffusion and catalytic oxidation. Novel electroless anode (28-32 vol\% Ni) is employed adjacent to YSZ electrolyte for effective electrochemical activity and thermal compatibility. Because of the presence of unique core (YSZ)-shell (Ni) microstructure, electroless anode is found to extend the anodic electrochemical reaction from electrolyte/anode interface to the bulk. Significant performance enhancement with current density of ∼3.3 Acm -2 is observed for single cells fabricated with multilayer anode at 800°C, 0.7V. The multilayer anode is found to reduce the cell degradation from ∼11\% (conventional anode) to ∼1.6\% /1000 h during long term performance (∼2000 h).",
