The results of the study show that the three phase boundaries in the SOFC anode Ni+YSZ are greatly increased by doping Ce 0.9 Ca 0.1 O 2- δ particles , and the transportation of oxygen ion in the anode is improved as well. By adding Ce 0.9 Ca 0.1 O 2- δ particles, the composite anode is produced and the anode reaction is accelerated, resulting in an improvement of SOFC output properties. The highest power density of SOFC with the anode of Ni+YSZ doped by Ce 0.9 Ca 0.1 O 2- δ particles in a weight ratio of 15%, which is about 3 times higher than that of SOFC with the anode Ni+YSZ without doping, is obtained.
