The porous structure of anodes in SOFCs is the key factor to improve its performance and the manufacturing method to control its design needs to be established. Additive manufacturing, so-called 3D printing technology can be a prospective method for the fabrication of electrodes of SOFCs. In this experiment, stereolithography, which is a form of 3D printing technology using UV-light with approximately 365nm wavelength and photo-curable resin, is applied. The UV-light that goes through pinholes enables the production of multiple cylindrical objects at once. As a result, the objects and the empty spaces between them make the porous structure. Moreover, by changing the size and the number of holes and distance between them, the fabrication of an anode with the desired microstructure can be expected.
