Tape casting and co-firing technique was applied to the fabrication of a planar solid oxide fuel cell. Yttria stabilized zirconia (YSZ), (La, Sr)MnO_3, Ni-YSZ cermet and (La, Ca)CrO_3 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)CrO_3 separator to the other parts of the cell. The densification of the (La, Ca)CrO_3 was impeded by the Ca migration.
