US 2011/0256464 A1 · Fuel Cell, Fuel Cell Module, Fuel Cell Device, and Method of Manufacturing Fuel Cell

Abstract

There are provided a fuel cell capable of suppressing damage to an end thereof, and a fuel cell module and a fuel cell device that include the fuel cell. In a fuel cell (1) wherein a fuel electrode layer (3) is formed on one of opposite main surfaces of a solid electrolyte layer (4) and an air electrode layer (5) is formed on the other of the main surfaces, and electric power is generated by utilizing a fuel gas and an oxygen-containing gas, an oxidation suppression layer (10) is located closer to the fuel electrode layer (3) than at least the solid electrolyte layer (4) on one end of the fuel cell (1), the oxidation suppression layer (10) being composed mainly of silicate containing at least one of elements belonging to Group 2 on the periodic table. This makes it possible to provide a fuel cell (1a) capable of suppressing damage to and oxidation of one end thereof.
