Optimized anode configuration with conventional anode ( 40 vol % Ni) towards fuel side and electroless anode (28/32 vol %) active layer (AAL) at electrode/electrolyte interface shows maximum current density of ~ 4.0 A.cm-2 @ 800oC & 0.7 V using 250 SCCM of moist H2 (3 % moisture) as fuel compared to much less performance (3A.cm-2) using dry fuel. Such layered anode also shows higher performance of 1.0A.cm-2 with 20 % reformed methane (RH:40 %) compared to 0.5 A.cm-2 obtained with SOFC fabricated with conventional anode. Electroless anode with unique core (Ni)-shell (YSZ) morphology uses lower Ni content to fulfill the required conductivity criteria and shows enhanced electrochemical reaction at electrode/electrolyte interface. Owing to such factors, electroless AAL shows much reduced coking of anode with reformed methane as fuel and enhance the endurance of SOFC with much higher performance. Keyphrases: Anode, SOFC, electrochemical performance
