Abstract
A cermet supported tubular SOFC was manufactured by thermal spray processes to aim at reducing the production cost. The effect of the anode microstructure on the performance of SOFC was investigated. The results show that the maximum output power density strongly depends on the anode microstructure. The length and density of the three-phase boundaries (TPB) can be increased by decreasing the particle size of YSZ and Ni in composite anode. The performance of SOFC can be improved by modifying the active TPB length and TPB density. It is revealed that the present SOFC of the distributed Ni/YSZ composite anode manufactured by thermal spray process reaches to a maximum output power density of 0.57 W/cm2 at 1000°C. All these results can be used for preparation of optimizing the anode structure.
