摘要： A stack structure includes plate-like electrochemical cells of ceramic, each having a pair of main surfaces and a side surface, and plate-like retainer pieces. The cell includes a first electrode in contact with first gas, a solid electrolyte, and a second electrode in contact with second gas. The first electrode has a gas flow channel formed therein and adapted to allow flow of the first gas. The cell has gas inflow and outflow ports. The retainer piece includes a body portion having a through-hole formed therein, and a pair of protrusions protruding from the body portion. The retainer piece has a communication hole formed therein and adapted to establish communication between the through-hole and a space formed between the protrusions. The cell is held by the paired protrusions, thereby establishing communication between the gas inflow or outflow port of the cell and the communication hole of the retainer piece.

摘要： The solid oxide fuel cell has a stack structure formed by stacking sheet bodies, each of which comprises three layers of the electrolyte layer, a fuel electrode layer, an air electrode layer, and separators in alternating layers. In an air channel defined between the air electrode and the separator facing the air electrode layer, a SUS mesh made of stainless steel for electrically connecting both of them is confined. On the surface of the SUS mesh, previously by itself before the assembly of the stack structure, an Ag-plating treatment is performed and further a vacuum heat-treatment (heat-treatment under a negative pressure) is performed.

摘要： An assembling method of a solid oxide fuel cell, having a stack structure in which sheet bodies and separators are stacked in alternating layers, includes a stacking step, a sealing step, and a reduction process step. In the sealing step, a laminate in which a crystallized glass material is interposed between the perimetric portions adjacent to each other is heated, so that the crystallization rate of the crystallized glass is increased to 0 to 50%. Accordingly, the perimetric portions adjacent to each other are integrated and sealed, and a room for glass softening is left. In the reduction process step, the laminate is heated, and a reduction gas is supplied into a fuel channel, whereby the reduction process is performed to the fuel electrode layer, and the crystallization rate is increased to 70 to 100%. Thus, the assembly of the fuel cell is completed.

摘要： A reduction process is performed to each fuel electrode layer by supplying a reduction gas into each fuel channel 22 in the state in which a perimetric portion of a sheet body 11 is held to be sealed by perimetric portions of an upper support member 122 and a lower support member 121. In the case of a small-sized fuel cell in which the thickness of the sheet body 11 is 20˜500 μm, the fuel electrode layer is greater in thickness than the solid electrolyte layer and the air electrode layer, and the area of the orthogonal projection of the plane portion 12a of each support member 12 is 1˜100 cm2, a ratio of a warpage of not more than 0.05 cm−1 on the sheet body with respect to the area of the orthogonal projection can be achieved at room temperature after the reduction process.

摘要： A fuel cell employs a stack structure in which a plurality of sheet bodies and a plurality of separators are stacked and joined together in alternating layers. Chemical reactions occur in the sheet bodies. The separators separate, from each other, two kinds of gasses (air and fuel gas) which are necessary for the chemical reactions. The plurality of separators consist of high-rigidity separator(s), and ordinary separators, which are lower in rigidity than the high-rigidity separator. This configuration reliably suppresses the occurrence of “separation of a joint region” attributable to “stress concentration caused by increase in the number of the stacked separators.
