Provided is a solid oxide fuel cell with long-term stability, small inside resistance and high power density which, at the same time, achieves to maintain excellent oxidation resistance, is capable of performing the process of fabricating the cell in the oxidation atmosphere at high temperatures at 1000 °C or more, and achieves reduction in the material cost. A porous metallic substrate is made of metal in which a coating containing aluminum is formed on the metal surface constituting the porous metallic substrate. Moreover, the porous metallic substrate is made of metal in which a coating, which contains aluminum and a high-conductive oxide generated by the phase reaction between elements contained in the metal constituting the substrate and elements contained in an oxidizer electrode, is formed on the metal surface constituting the poro' is metallic substrate. |
