Abstract: A solid-state battery including a solid-state battery laminate having a positive electrode layer, a negative electrode layer, and a solid electrolyte layer interposed between the positive electrode layer and the negative electrode layer, each of the positive electrode layer and the negative electrode layer having an electrode active material. A first active material contour portion in which the electrode active material in one of the positive electrode layer and the negative electrode layer extends to a first plan-view contour of the solid-state battery laminate, and a first non-active material contour portion in which the electrode active material in the other of the positive electrode layer and the negative electrode layer does not extend to the first plan-view contour of the solid-state battery laminate face each other in a lamination direction.

Abstract: A solid-state battery including a solid-state battery laminate having a positive electrode layer, a negative electrode layer, and a solid electrolyte layer interposed between the positive electrode layer and the negative electrode layer; and a positive electrode external terminal connected to the positive electrode layer and a negative electrode external terminal connected to the negative electrode layer are on a same surface of the solid-state battery laminate.

Abstract: A solid-state battery that includes a solid-state battery layered body including a positive electrode layer, a negative electrode layer, and a solid electrolyte interposed between the positive electrode layer and the negative electrode layer, wherein at least one electrode layer of the positive electrode layer and the negative electrode layer has a tapered shape toward an edge of the electrode layer in a sectional view thereof, and the positive electrode layer, the negative electrode layer, and the solid electrolyte are an integrally sintered body.

Abstract: A solid oxide fuel cell stack has a surface from which via conductors for drawing a current are exposed. Collector plates are disposed on the surfaces of the fuel cell stack so that one main surface of the collector plates faces the via conductors. Fixing plates are fixed to the collector plates. Spacers are disposed between the fuel cell stack and the fixing plates. An adhesive fixes the fixing plates to the fuel cell stack through the spacers.
