Abstract
A solid oxide fuel cell assembly comprises at least one planar fuel cell consisting of a solid oxide electrolyte sandwiched by an anode and a cathode, and at least two gas separators having gas passages for supplying anode gas and cathode gas to said anode and cathode. The at least one fuel cell and at least two separators are arranged one on the other to form a fuel cell assembly. The gas separators except for the uppermost separator are integrally provided at its periphery with an upwardly extending side wall spaced from adjacent upper gas separator to form a space surrounding the fuel cell located thereon, and the space is charged with a nonconducting high viscous melt. The fuel cell assembly may comprises a plurality of planar fuel cells and a plurality of planar separators arranged one on the another to form a fuel cell stack and may be arranged in a open-topped box-like housing charged with a nonconducting high viscous melt.
