Abstract:
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 AXO 3 -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 P a  of 10% or more by volume when I Ni /I NiO ≤0.1, where I Ni /I NiO  denotes a relative intensity ratio of the peak intensity I Ni  of metallic Ni to the peak intensity I NiO  of the NiO in an XRD spectrum of the anode.

Claim (Index 1):
A solid oxide fuel cell comprising a cell structure including a cathode, an anode, a protonically conductive solid electrolyte layer provided between the cathode and the anode, an oxidant channel to supply an oxidant to the cathode, and a fuel channel to supply a fuel to the anode,\n wherein the solid electrolyte layer and the 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 AXO 3 -type crystal structure, an A-site containing Ba, an 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, and the anode has a porosity P a  of 10% or more by volume when I Ni /I NiO \u22640.1, where I Ni /I NiO  denotes a relative intensity ratio of a peak intensity I Ni  of metallic Ni to a peak intensity I NiO  of the NiO in an X-ray diffraction spectrum of the anode.
