전사법을 이용하여 제조한 SOFC 단전지의 특성 분석

The properties of manufactured SOFC unit cell using decalcomania method were investigated. The decalcomania method that used in ceramics, dish, vessel and etc. was the very simple process. The SOFC unit cell manufacturer using decalcomania method is very simple process. Especially, the decalcomania method was the most suitable manufacturing method for the segmented type SOFC. The cathode, prevent diffusion layer (PDL), anode functional layer (AFL) and electrolyte were manufactured using decalcomania method on porous anode support. The sintered electrolyte at 1450℃ for 2 h using decalcomania method was very dense, and the thickness was about 10 μm. The cathode, the PDL and the AFL were manufactured using decalcomania method and was sintered at 1250℃ for 2 h, and the sintered electrodes were the porous. As a result, with humidified hydrogen used as fuel, the cell with an 15 μm-thick AFL exhibited maximum power densities of 0.246, 0.364, 0.504W/cm2 at 700, 750, 800℃, respectively.
