Metal-supported SOFCs are very attractive due to their high mechanical strength, thermal conductivity, and low material cost. These properties make SOFCs suitable for mobile application as well as the traditional stationary application. Contrary to many researches, using the thin-metal support will be more suitable for potable application because it provides the cell with flexibility, light weight, and good stacking property. In this study, thin metal-supported SOFC (~100μm) was fabricated and tested. Green sheets of thin STS support, Ni-YSZ anode, and YSZ electrolyte were prepared by tape casting method in order to fabricate the single cell. Three tapes were laminated and co-fired at 1300oC in reducing atmosphere. Microstructure of 3-layered cell was examined and the performance was tested with a LSCF cathode at 800oC. Thin and strong metal-supported SOFC was successfully fabricated by co-firing process. Total thickness of the sintered cell was ~80μm. This thin cell showed flexible nature and was easily bent without visible cracks on the electrolyte. The Cr-poisoning of Ni in the anode was occurred during sintering at high temperature, which could lower the cell performance. Cr diffusion barrier may be used in order to enhance the cell performance.
