The porous microstructure of SOFC electrodes significantly affects the SOFC performance. It is necessary to understand the diffusion process through the complex microstructure in order to improve the performance of SOFC. 3D-printed enlarged models based on practical microstructure of SOFC anode obtained by FIB-SEM observation were prepared for possible application to diffusion experiments. The 3D models were evaluated in the point of gas tightness and strength. Furthermore, reproducibility of the complex microstructure by a 3D printer was tested by examining the difference between the original FIB-SEM data and the 3D-printed microstructure. The result shows both the possibilities and limitations of this method.
