The present study aims to establish the fabrication technology of electrode films for micro solid oxide fuel cells (SOFCs) by the green tape laser sintering (GTLS) method. We used a Nd:YAG laser to sinter the green tape of electrode film materials on an electrolyte substrate. The materials are samaria doped ceria (SDC) for the electrolyte, samarium strontium cobaltite for the cathode, and cross-linked polyethylene monodisperse particles for the pore-forming agent. We controlled laser energy by changing the focus position in the experiment. As a result, the area ratio of the film pores is 20 % under the following conditions: laser energy, 0.23 mJ; scan speed, 200 mm/min; pulse width, 1.2 ms; repetition frequency, 80 Hz; defocus, 16 mm.
