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

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 adjacent to at least one of the cathode and the anode and having a three-dimensional mesh-like skeleton; a second porous metal body stacked to be adjacent to the first porous metal body and having a three-dimensional mesh-like skeleton; and an interconnector adjacent to the second porous metal body. The first porous metal body has a pore size smaller than a pore size of the second porous metal body.
