Abstract
The invention relates to a solid-electrolyte fuel cell including an anode that is intended to be in contact with a fuel; a cathode that is intended to be in contact with an oxidant for oxidizing the fuel; and a first oxygen-ion-conductive (electrolyte) film and a second oxygen-ion conductive film that are stuck together, are connected with the anode and the cathode, and are arranged in descending order toward the anode, by activation energy of oxygen ion. According to the fuel cell, it becomes possible to increase the open-circuit voltage.
