Abstract: An electrochemical cell includes a porous support substrate and a power generation element portion. The support substrate includes at least one first gas channel and at least one second gas channel. The first gas channel extends from a first end portion toward a second end portion, and is connected to a 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 endportion, and is connected to a gas collection chamber. A ratio (p0/L) of a pitch p0 of a first gas channel and a second gas channel that are adjacent to each other to a distance L between the power generation element portion and a first end surface of the support substrate located on the first end portion side is 3.3 or less.

Abstract: 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.

Abstract: A manifold includes first and second manifold main bodies. The first manifold main body includes a gas supply chamber that is connected to a first gas channel, and the second manifold main body includes a gas collection chamber that is connected to a second gas channel. The first manifold main body includes a first top plate, a first bottom plate, and a first side plate. The first top plate includes a first through hole for connecting the first gas channel and the gas supply chamber. The second manifold main body includes a second top plate, a second bottom plate, and a second side plate. The second top plate includes a second through hole for connecting the second gas channel and the gas collection chamber. The first bottom plate and the second bottom plate are constituted by members that are separate from each other.

Abstract: A cell stack device includes a manifold, a fuel cell, and an oxygen-containing-gas ejection portion. The manifold includes a fuel gas supply chamber and a fuel gas collection chamber. The fuel cell extends upward from the manifold. The oxygen-containing-gas ejection portion is disposed upward of the center of the fuel cell. The oxygen-containing-gas ejection portion ejects oxygen-containing gas toward the fuel cell. A support substrate of the fuel cell includes a first gas channel and a second gas channel. The first gas channel is connected to a fuel gas supply chamber, and the second gas channel is connected to the fuel gas collection chamber. The first gas channel and the second gas channel are connected to each other in an upper end portion of the fuel cell.

Abstract: A fuel cell comprises an anode, a cathode, and a solid electrolyte layer disposed between the anode and the cathode. The cathode includes a main phase configured by a perovskite oxide including at least one of La or Sr at the A site and that is expressed by the general formula ABO3, and a secondary phase configured by strontium oxide. The occupied surface area ratio of the secondary phase in a cross section of the cathode is greater than or equal to 0.05% and less than or equal to 3%.

Abstract: A separation membrane complex includes a porous support and a separation membrane formed on the support and used to separate fluid. A supply/permeation area ratio obtained by dividing a supply-side surface area by a permeation-side surface area is higher than or equal to 1.1 and lower than or equal to 5.0, the supply-side surface area being the area of a region of the surface of the separation membrane to which fluid is supplied, the permeation-side surface area being the area of a region of the surface of the support from which fluid that has permeated through the separation membrane and the support flows off.

Abstract: A fuel cell stack includes a fuel manifold and a fuel cell. The fuel cell extends from the fuel manifold. The fuel cell includes a support substrate and a plurality of electricity generating elements. The support substrate includes a gas flow pathway extending along a lengthwise direction. The plurality of electricity generating elements are disposed on the support substrate, while being disposed away from each other at intervals along the lengthwise direction. A base end-side electricity generating element disposed as gas supply-side endmost one of the plurality of electricity generating elements has an area greater than an average area of the plurality of electricity generating elements except for the base end-side electricity generating element.
