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.

摘要： A porous metal body including a skeleton having a three-dimensional mesh-like structure, the porous metal body having a plate-like overall shape. The skeleton has a hollow structure and includes a primary metal layer and at least one of a first microporous layer and a second microporous layer. The primary metal layer is composed of nickel or a nickel alloy. The first microporous layer contains nickel and chromium and is disposed on the outer peripheral surface of the primary metal layer. The second microporous layer contains nickel and chromium and is disposed on the inner peripheral surface of the primary metal layer, the inner peripheral surface facing the hollow space of the skeleton.

摘要： In an SOFC, a solid electrolyte layer and an anode are integrated with each other to provide an electrolyte layer-anode assembly. The anode contains a nickel element and a first proton conductor. The first proton conductor is composed of a first perovskite oxide having proton conductivity. The first perovskite oxide has an AXO3-type crystal structure, the A-site containing Ba, the X-site containing Y and at least one selected from the group consisting of Zr and Ce. The nickel element is at least partially in the form of NiO. The anode has a porosity Pa of 10% or more by volume when INi/INiO≤0.1, where INi/INiO denotes a relative intensity ratio of the peak intensity INi of metallic Ni to the peak intensity INiO of the NiO in an XRD spectrum of the anode.
