| Abstract | Cermet supported cells with Sm0.2Ce0.8O1.9 (SDC) electrolyte have been developed and scaled up to 55mm x 55mm at NRC-IFCI. A solid oxide fuel cell with SDC electrolyte of 10µm in thickness and Ni-SDC anode of 15µm in thickness on a 0.8mm thick Ni-YSZ cermet substrate was fabricated by tape casting, screen printing, and co-firing. A composite cathode, 75 wt% Sm0.5Sr0.5CoO3 (SSCo) + 25 wt% SDC, approximately 50µm in thickness, was printed on the co-fired half-cell, and sintered at 1000{degree sign}C. The cell with effective cathode area of 16 cm2 showed a high electrochemical performance at 600{degree sign}C, and peak power density of 0.9W cm-2 was obtained with hydrogen fuel. |
