    Abstract: An electrode includes a metal porous-body sheet formed of a metal porous body having a skeleton, the skeleton having a three-dimensional network structure, and a metallic support body having a plate shape and disposed on one main surface of the metal porous-body sheet. The one main surface has a plurality of machined holes each formed perpendicularly to the one main surface, and at least some of the plurality of machined holes are disposed at equal intervals. The metallic support body has a plurality of through holes extending through two surfaces of the metallic support body, and at least some of the plurality of through holes are disposed at equal intervals. A center of each of the some of the plurality of machined holes and a center of each of the some of the plurality of through holes are shifted from each other in one direction in plan view.

    Abstract: A fuel cell includes a MEA that includes a cathode, an anode, and a solid electrolyte layer disposed between the cathode and the anode, the solid electrolyte layer containing an ion-conducting solid oxide; at least one first porous metal body arranged to oppose at least one of the cathode and the anode; and an interconnector arranged to oppose the first porous metal body and having a gas supply port and a gas discharge port formed therein. The first porous metal body includes a porous metal body S that opposes the gas supply port and has a three-dimensional mesh-like skeleton, and a porous metal body H that has a three-dimensional mesh-like skeleton and is other than the porous metal body S. A porosity Ps of the porous metal body S and a porosity Ph of the porous metal body H satisfy a relationship: Ps
