摘要： A fuel cell includes a porous support substrate and a power generation element portion. The support substrate includes a first end portion that is linked to a gas supply chamber and a gas collection portion, and a second end portion that is located opposite to the first end portion. The support substrate includes a first gas channel and a second gas channel. The first gas channel extends from the first end portion toward the second end portion. The first gas channel is connected to the gas supply chamber. The second gas channel is connected to the first gas channel on the second end portion side. The second gas channel extends from the second end portion toward the first end portion. The second gas channel is connected to the gas collection chamber. The support substrate is configured such that gas flows in the support substrate and moves between the first gas channel and the second gas channel, in a portion of the support substrate that is farther toward the first end portion side than the power generation element portion is.

摘要： An electrochemical cell stack according to a first aspect of the present invention includes an electrochemical cell and a manifold supporting a base end of the electrochemical cell. The electrochemical cell includes an electric insulative support substrate and a plurality of power generation units disposed on the support substrate. Additionally, a gas flow path is provided in the support substrate. Each of the plurality of power generation units includes an anode, a cathode, and a solid electrolyte layer disposed between the anode and the cathode. Additionally, the solid electrolyte layer contains a zirconia-based material as a main component thereof. In a distal end side power generation unit, which is farthest from the manifold among the plurality of power generation units, the solid electrolyte layer includes a first area covering within 3 μm from an anode side surface, and a second area provided on the first area. An intensity ratio of tetragonal zirconia to cubic zirconia in a Raman spectrum in the first area is greater than an intensity ratio of tetragonal zirconia to cubic zirconia in the Raman spectrum in the second area.

摘要： Provided is a fuel cell as a fired body including a porous plate-like support substrate having a gas flow path formed therein, and a power generation element part provided on a principal surface of the support substrate, the power generation element part including at least a fuel electrode, a solid electrolyte, and an air electrode laminated in this order. The generation of cracks in the support substrate has a strong correlation with a “surface roughness of a wall surface of a gas flow” of the fuel cell in a state of a reductant. When the surface roughness of the wall surface of the gas flow path is 0.16 to 5.2 in terms of an arithmetic average roughness Ra in a state in which the fuel cell is a reductant that has been subjected to heat treatment in a reducing atmosphere, the generation of the cracks can be suppressed.
