Abstract
The invention relates to a fuel cell having superior durability by suppressing a reaction between a component contained in a solid electrolyte and an oxygen-side electrode during a long-period operation, a fuel cell stack and a fuel cell apparatus using thereof. A fuel cell () includes a solid electrolyte () containing Zr, an intermediate layer () and an oxygen-side electrode () that are disposed in this order on one surface of the solid electrolyte (), and a fuel-side electrode () disposed on another surface opposed to the oxygen-side electrode () of the solid electrolyte (). The intermediate layer () includes a surface layer region () that contains Zr and is on a side of the solid electrolyte (), and another region () except the surface layer region () that does not contain Zr. Accordingly, it is possible to suppress a reaction between Zr and the oxygen-side electrode () and suppress power generation performance degradation of the fuel cell ().
