The flow passages on the two groups of connectors in the structure are intersected with each other, so that the lower surface of each group of membrane electrode 18 flows through fuel gas, the upper surface flows through air (oxygen), the flow direction is intersected to be 90 degrees, the fuel gas which is introduced through the fuel gas inlet 3 and the fuel gas outlet 7 on the left side and the right side of the fuel gas side connector is blocked by the sealing piece 19 and cannot enter the upper layer area of the membrane electrode 18, and the air (oxygen) which is introduced through the air inlet 6 and the air outlet 8 on the upper side and the lower side of the fuel gas side connector is blocked by the sealing piece 19 and cannot enter the lower layer area of the membrane electrode 18.
In the structure, the connectors on two sides of the single cells relatively rotate by 90 degrees, the channels are mutually crossed by matching with the gas circuit design, and the sealing materials are matched to prevent fuel gas and air (oxygen) from being mixed, so that each group of single cells can be well supplied with fuel gas and air (oxygen), and the fuel gas and air (oxygen) can be prevented from entering and exiting from the same side, and the risks of explosion and the like caused by air flow mixing are avoided.
As shown in fig. 2, the two ends of the trapezoid runner 4 are provided with a first gas-liquid inlet and a first gas-liquid outlet 10, the first gas-liquid inlet and outlet 10 is communicated with a first medium inlet and a first medium outlet, when the connector is positioned on the gas side, the first gas-liquid inlet and outlet 10 is communicated with the gas inlet 3 and the gas outlet 7, and when the connector is positioned on the air side, the first gas-liquid inlet and outlet 10 is communicated with the air inlet 6 and the air outlet 8.

The flow channels of fuel gas, air (oxygen) and the like in the connectors are all through, so that gas and liquid can enter different single cells simultaneously after a plurality of groups of connectors are stacked.
As shown in fig. 3, two metal connectors are combined together in a relatively crossed manner, and a partial side view schematic diagram of the membrane electrode is sandwiched therebetween, the flow channels of the metal connectors are crossed with each other and are not in the same direction, the air flow channel 14 is located at the position of the trapezoid flow channel 4 in fig. 1, that is, after the trapezoid flow channel on the air side connector is communicated with the air inlets and outlets 6 and 8, the air flow channel 14 shown in fig. 3 is formed, and correspondingly, the first air inlet and outlet 10 in fig. 2 corresponds to the position of the second air inlet and outlet 11 in fig. 3.
As shown in fig. 4, a plurality of groups of single cells are uniformly arranged on each group of single cell mounting positions, the membrane electrodes 18 of the single cells are connected with the air side metal connector 17 positioned at the top, and sealing materials filled between two adjacent groups of single cells form a sealing piece 19.

In this embodiment, a square connector with a large size is designed and produced, and a plurality of single cells are arranged in the connector, as shown in fig. 4. After the single cells are arranged, the sealing material is filled in the arrangement gaps of the single cells. And then the other half of the metal connector is pressed against the sealing material to complete the assembly of the single cell. The single-cell is thus mounted like a lattice arrangement of multiple cells, as is the case with a large-scale stack. The cells are orderly arranged to form a large-scale electric pile, and the effective area of each small cell is 100cm 2 Calculating that the area of the single large battery can reach 2500cm 2 (5*5 series) in a 100-piece single cell stack, the effective catalytic area was 250000cm 2 At 4W/cm 2 The stack may reach the megawatt level. While avoiding excessive stack length, more rows of cells, such as 6*6, 5*6, 8 x 8, 10 x 10, etc., may be used.
The structure can realize the large-scale and high-power product single-pile landing of technical products such as SOFC (SOEC), PEM fuel cells (electrolytic cells) and the like.
The adopted metal connector realizes the single-stack megawatt level, takes the easily-formed metal connector as a matrix, embeds the structures such as membrane electrodes, sealing layers, diaphragms and the like which are not easily formed therein, forms lattice arrangement, avoids the redundancy of the number of small stacks under the high-power stacks, avoids complex waterway design, circuit design and gas circuit design, and avoids unnecessary energy loss.
Shan Dui has advantages such as temperature uniformity and convenient control than a plurality of piles.
The single-cell stack is more stable than the single-cell stack with the traditional large single-cell stack, the risk of lowering the yield of key materials of the large single-cell is unavoidable while the large single-cell is pursued, and the single-cell method with the lattice small single-cell is pursued, so that the yield of products can be well controlled.
The gas-liquid communication between different small batteries depends on the sealing path communication formed between the flow channels of the connecting bodies and the sealing materials,
after entering one side of the battery, the fuel gas (liquid) passes through the fuel gas flow channel, and after the reaction of the first small module, the fuel gas (liquid) enters the next small module through the sealing flow channel formed between the connecting body and the sealing material, so that the common reaction result of a plurality of modules is realized.
The air-side flow passage is the same as the fuel flow passage in the flow manner, but the flow passage directions of the two flow passages intersect.
The structure is connected between different electric piles by pipelines, and the electric pile connector is made of metal, belongs to natural good conductors and can serve as circuit connection between the electric piles, so that the method can greatly reduce the pipeline connection and circuit connection between the traditional electric piles and avoid unnecessary energy loss.
In the traditional pile design scheme, if megawatt level is to be realized on the premise that key core materials cannot be made large, n small piles are required to be connected in series and parallel, and gas paths, waterways and circuit connection among the small piles become very complex. And the temperature between the electric pile and the electric pile is difficult to uniformly regulate and control, which is unfavorable for the whole service life and efficiency of the product.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
