    摘要： 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

    摘要： There is provided a composite material for a fuel cell, in which in the case where an electrolyte-anode laminate is co-fired, the composite material is capable of inhibiting a decrease in the ion conduction performance of a solid electrolyte layer to enhance the power generation performance of the fuel cell. A composite material 1 for a fuel cell includes a solid electrolyte layer 3 and an anode layer 2 stacked on the solid electrolyte layer, in which the solid electrolyte layer is composed of an ionic conductor in which the A-site of a perovskite structure is occupied by at least one of barium (Ba) and strontium (Sr) and tetravalent cations in the B-sites are partially replaced with a trivalent rare-earth element, the anode layer contains an electrolyte component having the same composition as the solid electrolyte layer, a nickel (Ni) catalyst, and an additive containing a rare-earth element, the additive being located at least at an interfacial portion with the solid electrolyte layer.
