“…2,3 We have studied the co-sintering of a three-layered flat cell of LSM-GDC/GDC/NiO-GDC prepared by tape casting, since the reaction between samarium doped ceria and LSM was not observed. 10,11 Electrical performance of the prepared microtubular cell was measured and was compared with that of a flat disc type cell. Possible ways to improve future cell performance will be discussed.…”
