摘要：

In the present paper, a three dimensional mathematic model of a solid oxide fuel cell (SOFC) with a gradient particle size anode was established to study the electrical performance of the SOFC. The effect mechanism of the gradient particle size anode on the cell performance was deeply discussed. Results show that the gradient particle size anode design can effectively reduce the anodic activation, concentration and ohmic overpotentials. The maximum output power density of the gradient particle size anode design in this paper can reach 0.90 W•cm-2, which is 2.59%, 10.30% and 16.26% higher than that of homogeneous SOFC with anode particle size of 0.5 µm, 1.0 µm and 1.5 µm, respectively. It can be concluded that the gradient particle size anode design can significantly improve the electrical performance of SOFC. © 2018, Science Press. All right reserved.
