    摘要： A electrochemical cell device includes: a cell having a first main surface and a second main surface opposite to the first main surface; a first current collector having a third main surface facing the first main surface; and a second current collector having a fourth main surface facing the second main surface. The cell is warped to protrude from the second main surface toward the first main surface. The third main surface is provided with a recess at a position facing a central portion of the first main surface. The fourth main surface includes a protrusion at a position facing a central portion of the second main surface. Each of the first current collector and the second current collector is constituted of one or more metal porous body sheets each composed of a metal porous body having a framework with a three-dimensional network structure.

    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.
