Abstract
Tape casting and co-firing technique was applied to the fabrication of a planar solid oxide fuel cell. Yttria stabilized zirconia (YSZ), (La, Sr) MnO3, Ni-YSZ cermet and (La, Ca) CrO3 were used as an electrolyte, a cathode, an anode, and a separator, respectively. Sheets of those materials were tape-cast with organic binder, laminated, and fired. A highly porous structure of the gas-distributor layer was formed using urethane-foam as a skeleton which can be burnt out during the firing process. Scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDX) revealed that (1) Mn in the cathode material diffused and dissolved into YSZ and (2) Ca migrated from the (La, Ca) CrO3 separator to the other parts of the cell. The densification of the (La, Ca) CrO3 was impeded by the Ca migration.Keywords
