<p>A solid oxide fuel cell stack in which first and second cell plates are alternately stacked. The first cell plates (5A) comprises a substrate (4) having a plurality of opening portions, a groove (42) which extends through the plurality of opening portions formed on a lower surface of the substrate, a solid electrolyte layer (3) which covers the opening portion formed on an upper surface of the substrate, a fuel electrode layer (1) which covers the opening portions formed on the solid electrolyte layer, and an air electrode layer (2) formed on the lower surface of the substrate so as to extend along the opening portions and the groove. The second cell plates (5B) has a structure in which the air electrode layer (2) is replaced with the fuel electrode layer in the first cell plate. In this fuel cell stack, the air electrode layer (2) of the first cell plate faces the air electrode layer (2) of the second cell plate, and the fuel electrode layer (1) of the first cell plate faces the fuel electrode layer (1) of the second cell plate. A method of manufacturing the solid oxide fuel cell stack comprises preparing the first cell plate, preparing the second cell plate, alternately stacking the first and second cell plates, and collectively sintering the stacked first and second cell plates.</p> |
