| Description |
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 800degC, 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).
