    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 cell structure, an oxidizing agent flow path, a fuel flow path, and an anode-side current collector. The cell structure includes a cathode, an anode, and a solid electrolyte layer disposed between the cathode and the anode. The oxidizing agent flow path is formed adjacent to the cathode and away from the solid electrolyte layer. The oxidizing agent flow path is a flow path for supplying a gas that contains an oxidizing agent to the cathode. The fuel flow path is formed adjacent to the anode and away from the solid electrolyte layer. The fuel flow path is a flow path for supplying a fuel gas that contains water vapor and a hydrocarbon to the anode. The anode-side current collector is disposed adjacent to the anode and away from the solid electrolyte layer. The anode-side current collector is in contact with the anode.
