1! IW6848FA VI. Description of the Invention: [Technical Field] The present invention relates to a solid oxide fuel cell, and an embodiment of the present invention particularly relates to a flat tubular solid oxide fuel cell and Production method. [Prior Art] After the first generation battery (dry battery) and the second generation battery (rechargeable battery), the developed fuel cell is called a third generation battery. Fuel cells convert the chemical energy produced by the oxides of fuel directly into electrical energy. According to this fuel cell, the reactants are continuously generated on the output side of the fuel cell system, and the product is continuously removed from the input side of the fuel cell system. In this way, electricity can be generated semipermanently. Furthermore, the fuel cell does not cause energy loss due to mechanical switching, so the conversion efficiency is quite high. The fuel cell can use various fuels such as fossil fuels, liquid fuels, and gaseous fuels, and can be classified into a low temperature form and a high temperature form depending on the operational loudness. Solid oxide oxides used in solid oxide fuel cells have oxygen ion conductivity or hydrogen ion conductivity, such as electrolytes, and operate at temperatures between 600 t and 1,000 ° C, which is the highest operating temperature of the fuel cell. Moreover, since the various elements have a solid form, the structure of the fuel cell is relatively simple and there are no problems such as electrolyte loss or filling. Furthermore, since no metal catalyst is required, the provision of fuel can be easily achieved by adjustment of the internal structure. In addition, hot gas will be generated during the power generation process, and the use of discharged heat energy to combine heat production and production capacity is also achievable. Because of the above-mentioned 201119121, the research and development of solid oxide fuel cells has mainly been developed, such as the United States and Japan, and it is hoped that the commercialization of solid oxide fuel cells will be achieved in the early 21st century.

The upper plate 丨1 A and the lower plate ΠΒ form a central portion of the cross section of the support column u of the fuel electrode, and are mutually supported and connected via at least two bridges β which extend vertically from the upper surface of the lower plate 11B. It is connected to the lower surface of the upper plate 11A in a straight line. Thus, the flat tubular solid oxide fuel cell comprises: a fuel electrode support column 11; a connecting member π which longitudinally passes through the central portion of the upper plate and has a rectangular cross section; an electrolytic layer 12 which is coated on the fuel electrode support The outer surface of the column 11 does not include the connecting member 13; and an air electrode 14 is coated on the outer surface of the electrolytic layer 12 and separated from the side surface of the connecting member by a predetermined distance d. The fuel electrode support column is formed by extrusion, and the electrolytic layer 2 and the air electrode 14 are formed by a coating process. 201119121

The flat tubular solid oxide fuel cell of the embodiment of the present invention can be made thinner than the conventional flat tubular solid oxide fuel cell which is conventionally produced by extrusion. Furthermore, a plurality of unit cells can be connected to each other in a (four) and/or parallel manner, so that a battery stack can be conveniently formed.

Fig. 22 is a view showing a method of manufacturing a solid oxide fuel cell according to another embodiment of the present invention. The 23rd ® is shown as a cross-sectional view along the line in Fig. 22 = ^ 凊 Referring to Figs. 21 to 23, the solid oxide fuel cell 1000 according to another embodiment of the present invention includes a channel support layer 11 a first battery layer 1200, a second battery layer 13 (9), a first functional layer, and a second functional layer 1500. The channel support layer 1100 includes a plurality of support portions 〇 with at least one flow path 1112 therebetween. After all of the 7G members of the forming portion ηι〇 are thinned, one end of the channel supporting layer 1110 perpendicular to the extending direction of the flow path 1112 is cut to open the inlet or outlet of the flow path 1112. The channel support layer mo may comprise ceramic, metal or a combination thereof. For example, the 'channel support layer" 100 can comprise a combination of oxidized (10) (eight), ysz, or YSZ with nickel. Furthermore, the channel support layer η(8) may comprise a group selected from the group consisting of at least one of a thermal expansion constant of between 6X10-V1 14xl0-6K·, a metal, and a metal oxide. Furthermore, the forming composition of the support layer 110 can be the same as the first functional layer 400 and the second functional layer 15〇〇' to enhance the strength of the solid oxide fuel cell surface. Unlike the first functional layer just as the second functional layer 15A, the structure of the support layer 1100 may have no holes. The widely distributed wind gas FG flows into the passage of the passage support layer 1100: 1112. For example, 'the fuel gas fg can be hydrogen (10), which is obtained by the combination of hydrogen and hydrocarbons, such as A 21 201119121 1 ννυ〇Η〇ΓΛ\ burning (CH4), C Burn (C3H8), or calcined (C4H10). Alternatively, the fuel gas FG may be a hydrocarbon gas. The first battery layer 1200 is disposed under the channel support layer 1100. The first battery layer 1200 includes a first fuel electrode layer 1210, a first electrolytic layer 122, and a first air electrode layer 123, which are sequentially disposed underneath. The first fuel electrode layer 1210 is disposed opposite to the channel support layer 11A. The first fuel electrode layer 丨21〇 contacts the hydrogen atoms flowing through the flow path 1112. The first fuel electrode layer 121 has a porous structure so that hydrogen gas can pass therethrough. The first fuel electrode layer 1210 may comprise an ion conducting material, such as a mixture of nickel and YSZ. When hydrogen (hydrocarbon) mixed with carbon flows into the flow path 1丨12, the first fuel electrode layer 1210 may contain copper to avoid formation of carbon. Alternatively, the first fuel electrode layer 1210 may contain cerium oxide (Ce 〇 2) for oxidizing carbon formed on the first fuel electrode layer 121 () and discharging the carbon gas. The first electrolytic layer 1220 may comprise a ceramic powder, such as YSZ, (La Sr)(Ga,Mg)〇3. Ba(Zr,Y)〇3 > GDC(Gd ## Ce02) > (4) Yf3 ΐ ΐ (5) 2), which have high ion conductivity and low... The high stability and high mechanical properties of Wei Yuyuan reaction. Wood 5, 苐 - electrolytic layer 1220 may comprise 8mo 丨 _YSZ. The two air electrode layers 123 and the oxygen-containing external gas (4) are: 1 = = = have a porous structure, so the oxygen can be interfaced = the layer 122° transmits the ions from the milk of the first air electrode (2), and this Ion system provided to the first - fuel electric right 22 201119121

1 ' TW6848PA 1210. This ion reacts with the fuel gas to produce electrons to provide water or electricity. When oxygen is directly in contact with hydrogen, power generation efficiency will be reduced. In order to avoid this, unlike the first fuel electrode layer 1210 and the first air electrode layer 1230, the first electrolytic layer 1220 may have a non-porous structure. Further, similarly to the channel support layer 1100, the width of the first electrolytic layer 1220 may be greater than the width of the first fuel electrode layer 1210 and the first air electrode layer 1230. The second battery layer 1300 is disposed on the channel support layer 1100. The second battery layer 1300 includes a second fuel electrode layer 1310, a second electrolyte layer 1320, and a second air electrode layer 1330. The second fuel electrode layer 1310, the second electrolytic layer 1320, and the second air electrode layer 1330 are substantially the same as the first fuel electrode layer 1210, the first electrolytic layer 1220, and the first air electrode layer 1230, except for The position is outside, so the repeated description is omitted here. The first functional layer 1400 is disposed between the channel support layer 1100 and the first battery layer 1200, and more specifically, between the channel support layer 1100 and the first fuel electrode layer 1210. The shape of the first functional layer 1400 may be a flat plate shape. The addition of the first functional layer 1400 is used to enhance strength or conduction, and the material of the first functional layer 1400 can be varied depending on different needs. The first functional layer 1400 has a porous structure, so hydrogen flowing in the flow path 1112 is transferred to the first fuel electrode layer 1210. When the porosity of the first functional layer 1400 is less than about 10% by volume, it is not easy to pass hydrogen through the first functional layer 1400. Thus, the electron generation efficiency of the first fuel electrode layer 210 can be reduced. When the porosity of the first functional layer 1400 is less than about 50 vol%, 23 201119121 may hardly increase strength or conductivity due to excess holes. Thus the first functional layer 1400 preferably has a porosity of between about 10 vol / 〇 to 50 vol %. More preferably, the first functional layer 14 has a porosity of between about 20 vol% and 40 vol%. More preferably, the first functional layer 14 has a porosity of between about 30 vol% and 40 vol/min. The formation of the porous structure of the first functional layer 1400 can be achieved by using a void forming agent. The embodiment of the void forming agent may include a carbon-based pore former, a polymer-based pore former, or a powder-killing pore former. Alternatively, the formation of the porous structure of the first functional layer 14 can be achieved by changing the manner in which the first functional layer 1400 is fabricated without the need for a void forming agent. The second functional layer 1500 is disposed between the channel support layer 11A and the second battery layer 1300, and more specifically, between the channel support layer η(8) and the second fuel electrode layer 1310. The second functional layer 1500 is substantially identical to the first functional layer 14A except for the configuration. In order to manufacture the solid oxide fuel cell, the first electrolysis plate, the first fuel electrode plate, and the first functional plate are thinned to form a first plurality. The laminate, and the second electrolytic plate, the second fuel electrode plate, and the -: functional plate are used to promote or conduct the force to form a second multilayer plate. A lanthanum system is disposed between the first and second multi-layer boards, and is two: UCKTCM, leaking. The temperature of the crucible is freshly connected, whereby the electrode layer 1210, the first electrolytic layer 2222, the first 1400, the channel domain layer, and the second (four) electrode layer are trained. The air electrode material is applied to the first electrolytic layer 1220 and the second electricity 24 201119121

'TW6848PA is layered under 1320 and soldered at a temperature of about 1,000 ° C to 1,300 ° C to form first and second air electrode layers 1230 and 1330. Thus, the solid oxide fuel cell 1000 can be fabricated. When the first and second air electrode layers 1230 and 1330 are formed, the first and second electrolytic layers 1220 and 1320 may be exposed upward or downward. A first through hole 1222 and a second through hole 1322 may be formed at the places where the first and second electrolytic layers 1220 and 1320 are exposed. The thickness of the surrounding portion of the solid oxide fuel cell 1000 may be the same as that of the central portion due to the pressure applied during the thinning process, as shown in Fig. 23. Figure 24 is a cross-sectional view taken along line VII to VT in Figure 22. Referring to Figure 24, the first and second functional layers 1400 and 1500 comprising ceramic, metal or a combination thereof may increase the strength of the solid oxide fuel cell 1000. In more detail, the solid oxide fuel cell 1000 having the first and second functional layers 1400 and 1500 has a strength greater than about 100 megapascals (MPa), and in this state, the solid oxide fuel cell 1000 is normally processed. At that time, the solid oxide fuel cell 1000 is hardly damaged. For example, the first and second functional layers 1400 and 1500 have a 3 mol-YSZ having a strength of about 200 MPa. The strength of 3 mol-YSZ may be about 5 to 8 times greater than that of 8 mol-YSZ, which is used to form first and second electrolytic layers 1220 and 1320. Table 1 first and second first and first and first channel strength electrolytic layer second burning two functional layer supporting material electrode layer 25 201119121 layer ratio 8mol-YSZ Ni-YSZ - 8mol - about 65 MPa than YSZ example 3mol- YSZ 3mol - about 347 MPa (porosity: 40 YSZ case vol%) Table 1 shows a solid oxide fuel cell manufactured by a practical example of the present invention and a comparative example, the size of a solid oxide fuel cell of 15x20 mm2 Measured by Tinius Olsen (UTM). Referring to Table 1, in the solid oxide fuel cell manufactured by the embodiment of the present invention, the first and second functional layers 1400 and 1500 are formed by 3 mol-YSZ and the porosity is about 40 vol%, and the channel support The composition of the layer 1100 is the same as that of the first and second functional layers, and the strength of this example is about 347 MPa. However, in the solid oxide fuel cell manufactured by the comparative example, the composition of the channel supporting layer and the first and second electrolytic layers are the same. 1220 is the same as 1230, but does not have first and second functional layers 1400 and 1500. The strength of this example is about 65 MPa, which is about one-fifth of the solid oxide fuel cell manufactured by the embodiment of the present invention. As described above, the solid oxide fuel cell 1000 including the first and second functional layers 1400 and 1500 can increase the strength, thereby reducing the possibility of damage due to an external force. A portion of each of the first and second electrolytic layers 1220 and 1320 is divided to form a first through hole 1222 and a second through hole 1322, and the first and the second 2011 19121

The filling of the first and second perforations 1222 and 1322 can be filled with a flat conductive adhesive or by a screen printing method. The shapes of the first and second perforations 1222 and 1322 may be polygonal. When the first and second through holes 1222 and 1322 are polygonal, the trailing ends of the first and second through holes 1222 and 1322 may be spherical. As such, the first and second connecting members 1700 and 1800 can have shapes corresponding to the first and second perforations 1222 and 1322. Correspondingly, the first and second connecting members 1700 and 1800 are in contact with the first and second fuel electrode layers 1210 and 1310, respectively. Thereafter, an air electrode material is applied and soldered to form first and second air electrode layers 1230 and 1330 to expose first and second perforations 1222 and 1322. When a plurality of single solid oxide fuel cells are combined with each other to form a battery stack, each single solid oxide fuel cell 1000 may have first and second connecting members 1700 and 1800, and exposed first and second connecting members 1700 And 1800 can be electrically connected to an external electronic device. The exposed first and second connecting members 1700 and 1800 compress the electrons generated by the first and second fuel electrode layers 1210 and 1310, and supply the electrons to the external electronic device to operate the external electronic device. The external electronic device can be a general electronic device driven by electricity or a battery. When the single solid oxide fuel cells 1000 are connected to each other in series, the first and second connecting members 1700 and 1800 are not exposed to each other, and the first and second adjacent solid oxide fuel cells are connected to the first one. The second air electrode layers 1230 and 1330. When the single solid oxide fuel cells 1000 are connected in parallel with each other, the first and second connecting members 1700 and 1800 that are not exposed are electrically connected to the first of a neighboring single solid oxide fuel cell. The second fuel electrode layers 121A and i3i〇; Fig. 25 is an enlarged schematic view showing another embodiment of the second connecting member in Fig. 24. In this embodiment, the first and second connecting members have the same structure. Therefore, the second connecting member will be described here. Referring to Fig. 25, the second electrolytic layer 1325 may have a plurality of perforations 1323 arranged in an area exposed to the outside and not covered by the second air electrode layer (10). The shape of the perforations 1323 may be a circular shape (circ—), as shown in the figure. Alternatively, the perforations 1323 may be polygonal in shape and the tails may be spherical. The shape of the connecting member 1 8 10 + J core may be the same as the through hole 1323 and may be inserted into each of the through holes 1323. For example, #咖L a 列石5兄, perforation 1323 can be filled with powder-containing colloid, wherein the powder has conductive ceramics, Bayi ^ ^ ^ 1 〇 1 Yumeng or a combination thereof, whereby t is a connecting member 1810 .

Page 97 You / 〇 Figure 22 The πth graph shows the relative change in conductivity and the nickel content of the first and functional layers of Figure 26. In this embodiment, the solid oxide kiss burning battery system is substantially the same as 28 201119121

' * TW6848PA The solid oxide fuel cell shown in Figure 24, except the first and second functional layers and the first and second fuel electrode layers. Therefore, the same elements are denoted by the same reference numerals and the repeated description is omitted. Referring to FIGS. 26 and 27 U, in a solid oxide fuel cell according to another embodiment of the present invention, the first and second functional layers 142 〇 and 152 〇 comprise a conductivity substantially greater than that of Siemens/cm (s/cm). Tauman, metal or a combination thereof. Furthermore, the first and second functional layers 1420 and 1520 preferably have a conductivity greater than that of Lanthanum Manganite. For example, at a temperature of about 800 C, the first and second functional layers 1420 and 1520 can comprise a pottery, a metal, or a combination thereof having a conductivity substantially greater than 55 Siemens/cm (s/cm), ie, manganic acid. The conductivity of 镧. For example, the first and second functional layers 1420 and 1 520 may comprise a mixture of 3 mol-YSZ and nickel. Since the conductivity is rapidly lowered at a nickel content of about 3 〇 v 〇 1%, the first and second energy layers 1420 and 1520 preferably have a nickel content of more than 30 vol%. For example, the first and second functional layers 1420 and 1520 may comprise a mixture of lanthanum chrome oxide (Lacr 〇 3) and carbon black. The first and second fuel electrode layers 1240 and 1340 can have third and fourth perforations 1242 and 1342 coupled to the first and second perforations 1222 and 1322, respectively. The third and fourth perforations 1242 and 1342 can each have substantially the same shape as the first and second perforations 1222 and 1322. The first and second connecting members 1750 and 1850 respectively pass through the third and fourth through holes 242 and 1342 and the first and second through holes 222 and 1322, so that the end portions of the first and second connecting members 1750 and 1 850 are Contact the first and the 29th 201119121 I ν» ν/ϋ~τυι r\ two functional layers 1420 and 1520. The side surfaces of the first and second functional layers 1420 and 1520 contact the first and second fuel electrode layers 1240 and 1340, respectively. As described above, when the first and second connecting members 1750 and 1850 are electrically connected to the first and second functional layers 1420 and 1520 and the first and second fuel electrode layers 1240 and 1340, the first and the second The two fuel electrode layers 1240 and 1340 effectively compress electrons. Thus, the power generation efficiency of the solid oxide fuel cell 2100 can be improved. Figure 28 is a schematic exploded view of a solid oxide fuel cell in accordance with still another embodiment of the present invention. Figure 29 is a cross-sectional view along line Μ and VDT in Figure 28. In this embodiment, the solid oxide fuel cell is substantially identical to the solid oxide fuel cell shown in Figure 26 except that the third and fourth functional layers are new. Therefore, the same elements are denoted by the same reference numerals, and the repeated description is omitted. Referring to FIGS. 28 and 29, a solid oxide fuel cell 2200 according to another embodiment of the present invention includes third and fourth functional layers 1450 and 1550 disposed between the channel support layer 1100 and the first functional layer 1420. And between the channel support layer 1100 and the second functional layer 1520. The third and fourth functional layers 1450 and 1550 can comprise ceramic, metal, or a combination thereof, such that the strength of the solid oxide fuel cell 2200 can be greater than about 100 MPa. For example, the third and fourth functional layers 1450 and 1550 can comprise 3 mol-YSZ having an intensity of about 200 MPa, as illustrated by the first and second functional layers 1400 and 1500 of FIG. As described above, when the solid oxide fuel cell 2200 includes third and fourth functional layers 1450 and 1550 and first and second functional layers 1420 and 1520 30 201119121

*, when TW6848PA is above and below the channel support layer 110, the increased intensity as described in Fig. 24 and the increased current rate as described in Fig. 26 will be achieved. When the thickness of the solid oxide fuel cell 2200 is increased by the first and second functional layers 1420 and 1520 and the third and fourth functional layers 1450 and 155, it will cause the step difference to become large to cause cracking. Thus, above and below the channel support layer 1100 adjacent the two sides of the solid oxide fuel cell 2200, the solid oxide fuel cell 2200 can further include first and second adhesion members 1600 and 1650' for removal and compaction. In this case, the gap. However, when the solid oxide fuel cell comprises one of the first and third functional layers 1420 and 1450 and one of the second and fourth functional layers 1520 and 1550, the drop is small, so that the first and second adhesions are not required. The members 16 are 1650. In order to form the first and second adhesive members 1600 and 1650, the one-and-reel-shaped flat plate and other members may be thinned in a manner similar to the manner in which the channel support layer 1100 is formed, and the flat plate does not include the adhesive members 1600 and 165. One of the remaining parts was removed. The first and second adhesive members 1600 and 1650 may comprise the same composition as the first and second electrolytic layers 1220 and 1320 or the channel support layer 1100. In this embodiment, the high strength layers of the third and fourth functional layers 1450 and 1550 are separated from the high conductive layers of the first and second functional layers 1420 and 1520. However, high-strength materials may be added to the first and second functional layers 1420 and 1520, respectively, to obtain a signal functional layer having both effects. The solid oxide fuel cell according to an embodiment of the present invention and a method of manufacturing the same can be applied to a portable battery, or a large battery of a power plant. Solid oxide fuel cells are conveniently connected in series with a small thickness of 31 201119121 vvuonor i degrees. Thus, a battery stack connected by a plurality of solid oxide fuel cells can have a smaller volume than a conventional battery stack.
