Abstract: Anew method for increasing the three-phase boundaries in anode of SOFCis reported. The results of the study show that the three-phase boundaries in the SOFCanode Ni+YSZare greatly increased by doping Ce0.9Ca0.1O2-δ particles , and the transportation of oxygen ion in the anode is improved as well. By adding Ce0.9Ca0.1O2-δ particles, the composite anode is produced and the anode reaction is accelerated, resulting in an improvement of SOFCoutput properties. The highest power density of SOFCwith the anode of Ni+YSZdoped by Ce0.9Ca0.1O2-δ particles in a weight ratio of 15%, which is about 3 times higher than that of SOFCwith the anode Ni+YSZwithouTdoping, is obtained.

Key words: SOFC, Anode, Ce0.9 Ca0.1 O2-δ particles, Three phase boundary
