Patent ID: 8722281

Claim:
A fuel cell, comprising: a columnar conductive support substrate comprises a fuel gas flow channel configured to be passing through therein for a flow of a fuel gas therethrough; and a fuel electrode layer, a solid electrolyte layer, and an air electrode layer laminated in that order on the columnar conductive support substrate, wherein one end of the fuel cell is configured to be a non-power-generation portion in which the fuel electrode layer and the solid electrolyte layer are laminated in that order on the conductive support substrate without the air electrode layer being laminated thereon, and one end of the non-power-generation portion comprises an oxidation suppression layer composed mainly of silicate containing at least one of elements belonging to Group 2 on the periodic table, and the oxidation suppression layer is continuously formed on the conductive support substrate and the fuel electrode layer at an end face of the non-power-generation portion and on the conductive support substrate within the fuel gas flow channel in the non-power-generation portion.
