A method for increasing the three-phase reaction boundaries in anode of SOFC

A new method for increasing the three-phase boundaries in anode of SOFC is reported. The results of the study show that the three-phase boundaries in the SOFC anode Ni + YSZ are greatly increased by doping Ce0.9Ca0.1O2-delta particles, and the transportation of oxygen ion in the anode is improved as well. By adding Ce0.9Ca0.1O2-delta particles, the composite anode is produ ced and the anode reaction is accelerated, resulting in an improvement of S OFC output properties, The highest power density of SOFC with the anode of Ni + YSZ doped by Ce0.9Ca0.1O2-delta particles in a weight ratio of 15%, wh ich is about 3 times higher than that of SOFC with the anode Ni + YSZ witho ut doping, is obtained.
