Patent ID: 7285348

Claim:
A fuel cell comprising an electrically conducting electrode-support substrate, an inner electrode layer, a solid electrolyte layer, an outer electrode layer and an interconnector, wherein said electrode-support substrate includes a flat plate portion having two flat surfaces which are in parallel with each other and forming a plurality of gas flow passages therein, and curved portions located at both ends of said flat plate portion; said interconnector is formed on one of the two flat surfaces of said flat plate portion of said electrode-support substrate; said inner electrode layer is formed on the other flat surface of said flat plate portion where the interconnector has not been provided, and the inner electrode layer may be extending from the other flat surface to the one flat surface through both curved portions; said solid electrolyte layer is laminated on said electrode-support substrate so as to cover said inner electrode layer, and is extending from the other flat surface of said flat plate portion up to both side ends of said interconnector passing through both curved portions; and said outer electrode layer is laminated on said solid electrolyte layer so as to be opposed to the other flat surface of said flat plate portion but so as not to be opposed to said curved portions, and its both ends are located on the other flat surface and on outer sides of corresponding portions to both side ends of said interconnector.
