本発明は、一枚の金属薄板で構成されるインクコネクタ
を使用する溶融炭酸塩燃料喧池積層体に関する。DETAILED DESCRIPTION OF THE INVENTION FIELD OF THE INVENTION The present invention relates to a molten carbonate fuel reservoir stack using an ink connector constructed from a single sheet of metal.

成したインターコネクタである。In general, a fuel cell is a stacked structure in which multiple unit cells are stacked on top of each other as shown in the first factor.The anode gas and cathode gas are mixed at the anode 1 and cathode 2 of adjacent unit cells in the stack. It is common to insert an interconnector made of a thin metal plate in order to magnetically connect adjacent unit cells in series.In addition, unit cell 3 in Figure 1 is a sleep cell. 4 is a current collector, and 5 is an interconnector forming a gas manifold.
第２図は、従来用いられてきたガス流を直交させるイン
タコネクタの第１の例の概略構成を示す斜視図である。FIG. 2 is a perspective view showing a schematic configuration of a first example of a conventionally used interconnector for orthogonal gas flows.
インタコネクタは、通常ステンレス鋼で構成され、２板
の波型薄板１１．１２の間に平薄板１５をはさんで、溶
接することによって作成される。The interconnector is usually constructed of stainless steel and is made by sandwiching a flat thin plate 15 between two corrugated thin plates 11, 12 and welding them together.
波型薄板１２の上に平薄板１５をのせ、この上Ｃ二液型
薄板１１を波型薄板１２の谷１４の方向が、波型薄板１
１の谷１３の方向と直交するようにのせ、波型薄板１１
，１２が同時に平薄板１５と接触する点を溶接する。A flat thin plate 15 is placed on top of the corrugated thin plate 12, and the C two-component thin plate 11 is placed on top of the flat thin plate 15 so that the direction of the troughs 14 of the corrugated thin plate 12 is the same as that of the corrugated thin plate 1.
The corrugated thin plate 11 is placed so as to be perpendicular to the direction of the valley 13 of 1.
, 12 are simultaneously welded at the points where they contact the flat thin plate 15.
このインタコネクタでは、金属薄板３枚で構成しなけれ
ばならず、厚みが大きくなることや、スポット溶接か必
要でセルサイズが大きくなるにつれ、スポット溶接点が
、＠１．速に多くなるという欠点があった。This interconnector must be composed of three thin metal plates, and as the thickness increases and the cell size increases due to the need for spot welding, the spot welding points become @1. It has the disadvantage that it increases rapidly.

面を気密に取着される。As an example of other laminates, there are some known examples of laminates, such as those shown in Figure 1b. is sandwiched between the cand electrode 22 and the anode electrode 23, and then the cylindrical electrode 22
．． A separator plate 25 having concave and convex portions arranged linearly on both surfaces of the intermediate portion of the separator plate 23 is disposed on the outside of the separator plate 23, and the peripheral contact surfaces are hermetically joined to form a C&layer. Each electrode 22
, 23 are smaller than the size of the electrolyte tile 21 and have a size that fits into the recess 26 of the electrolyte tile 21 and covers the uneven portion of the separator 25. In addition, through holes 27 for gas flow are arranged and opened along two opposing sides of the electrolyte tile 21, and when stacked, a gas flow gap is formed around the through holes 27 and between the electrolysis tile 21 and the separator 25. A spacing ring 28 having a plurality of conical protrusions for forming a full-length spacing ring 28 is attached in a gas-tight manner to the contact surfaces.

題′８Ａ２２．２３に供給される。In this structure, the fuel gas A1 and the oxidant gas B supplied through the through hole 27 are supplied to the spacer ring 2.
Oxidizing gas B
The fuel gas A flows in the same direction through the gas passages on the front side of the separator 25 in Figure 3 (at), and the fuel gas A flows on the back side of the separator plate 25 in the same direction.

合が少ないという欠点を有している。In the case of the above structure, a relatively wide gap must be provided as an internal gas manifold around the electrolyte tile for gas circulation, and the electrolyte mail may be partially interlaced around the through hole, resulting in destruction of the electrolyte tile. It is easy to cause damage such as the occurrence of cracks, and in particular, as the number of laminated layers increases, a large amount of gas must flow, and the probability of ζ2 damage increases as the dimensions increase. Further, the electrolyte tile has the problem of complicating the processing process because through holes must be made, and the problem of clogging of the gas flow path in the spacer ring portion. In addition, in the gas manifold area around the C-secondary electrolyte tile, if cracks occur in the electrolyte tile, the differential pressure between the fuel gas and oxidizer gas at operating temperatures will upset the retention balance of molten carbonate, causing the gas to leak. Foaming and cross-mixing are likely to occur,
There is a problem in that this cross-mixing becomes more pronounced as the temperature increases or decreases. Furthermore, since the gas manifold is formed around the C2 electrolyte tile, there is a drawback that the ratio of the cold electrode to the size of the electrolyte tile is small and the degree of utilization of the electrolyte tile is small.

Bend it upward, bend the remaining parts of the two sides downward, and then gradually reduce the diameter of the circular bottom of the upper protrusion along the bank direction, and change the diameter of the circular bottom of the lower protrusion to the upper surface. This is a molten carbonate fuel cell stack characterized by forming an interconnector that electrically connects stacked cells and isolates fuel oxidizer gas by gradually decreasing the size in the opposite direction.

を特徴とする溶融炭酸塩燃料電池積層体。In a fuel cell using molten carbonate as a solubilizer, a truncated cone-shaped convex portion is provided on the front and back sides of one thin metal plate, and a first bank for loading an electrode is provided on two opposing sides of one surface, A second bank is provided on the same side as the side with the first bank on the other side, and a gas flow path closing plate is provided at a diagonal position on the two sides that do not have the bank and from the corner to the center of the side. alternately in the upper and lower surfaces
The structure includes an interconnector for electrically coupling between the laminated cells and isolating the fuel oxidizing gas, in which the diameter of the circular bottom of the convex portion is gradually reduced along the longitudinal direction of the bank, and an interconnector that is placed on the bank C2. A molten carbonate fuel cell stack is characterized in that it is constructed by sequentially stacking molten carbonate ponds.
