Abstract |
In this study, we fabricated anode-supported solid oxide fuel cells by the decalcomania method. To investigate the effect of the anode functional layer (AFL) in a cell, AFL decalcomania paper was coated between the electrolyte and the anode support. The results showed that the surface roughness of the electrolyte coated on the anode support was not uniform (Ra = 7.86 nm), but that of electrolyte coated on AFL was uniform. A thin electrolyte layer with very low surface roughness was obtained. Then Ra was 2.65 nm. In this case, while the output power of the cell with the AFL (Cell 2) had an open circuit voltage (OCV) of 1.12 V and a maximum power density (MPD) of 650 mW cm-2 at 800℃, the cell without the AFL layer (Cell 1) had an OCV of 0.9 V and an MPD of 635 mW cm- |
