Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a fuel cell, and in particular, to a fuel cell that can improve the thermal stress strength of an electrolyte plate of a molten carbonate fuel cell.

The unit cell here has electrode plates (anode 2 and cathode 3) formed of a porous material and to which a catalyst is added on both sides of an electrolyte plate 1, and an anode 2 on the back of both electrode plates. A flow path formed by a plurality of parallel ribs that supplies fuel to l#! 5 and the cathode 3 through a separator plate 4 having an oxidizing agent passage groove 6 formed by a plurality of parallel ribs for supplying an oxidizing gas to the cathode 3. In FIG. 5, a wet seal 7 is inserted between the separator 4 and the electrolyte plate 1 in FIG. 0, which shows a cross-sectional view of the unit cell shown in FIG. This is to seal the gas flowing inside the cell.

が適しているからである。In the device having the above configuration, lithium aluminate powder (half of LiA Q Ox) is used as the material of the electrolyte plate 1.
It is constructed using a porous ceramic plate mixed with alumina fiber etc. as a reinforcing agent, and LixC is used as an electrolyte.
A mixture of carbonates such as os, KzCOa, NaC0a, etc. is used to impregnate the inside of the electrolyte plate. This electrolyte is fixed at room temperature, but melts when the temperature exceeds about 490° C., flows out to the interface between the electrode and the separator groove, causes a chemical reaction, and generates electricity. Also, as an electrode material, N is added to the anode side.
i. Porous sintered body, NiO porous body is used on the cathode side, and the material of the separator plate is austenitic stainless steel, for example, 5US316.5US304°5US
A high temperature corrosion resistant material such as 310.5 US 446 was used. This is because a reduction reaction due to hydrogen occurs on the 7 node side, and an oxidation reaction due to oxygen in the air occurs in an alkaline atmosphere on the cathode side, so austenitic steel with corrosion resistance is suitable.
上記構成材料等からなる単位セルは、反応性能向上およ
び外部へのガスの流出を防止するため一定荷重により圧
縮された状態で積層されている。The unit cells made of the above-mentioned constituent materials are stacked in a compressed state under a constant load in order to improve reaction performance and prevent gas from flowing out.

［および電解質板を一体で製作すれば電池性能は向上し

易となることがわかった。This means that since electricity is generated by the reaction at the electrode 2, the better the adhesion between the electrode 2 and the separator 4, the better the performance. Therefore, the separator, f
[It was also found that if the electrolyte plate is manufactured in one piece, the battery performance will be improved, and the completed product for each unit cell will facilitate the assembly and repair of the laminated battery.
次に、第６図ａには、電池運転時の起動停止特性が示さ
れている６発電前にセルの温度を定格温度まで上昇させ
る。その後、燃料および酸化剤ガスを流入して発電させ
る。停止時には、ガス停止後セル温度を降下させるよう
にしたものである。Next, FIG. 6a shows the start-stop characteristics during battery operation.6 Before power generation, the temperature of the cell is raised to the rated temperature. After that, fuel and oxidant gas are introduced to generate electricity. When the cell is stopped, the cell temperature is lowered after the gas is stopped.
従来、燃料電池は火力発電設備の代替として有望であり
、国内においては原子力発電設備をベース負荷運用とし
、燃料電池は日負荷運用として用いられることが予想さ
れる。Conventionally, fuel cells have been promising as a replacement for thermal power generation equipment, and in Japan, it is expected that nuclear power generation equipment will be used for base load operation and fuel cells will be used for daily load operation.
したがって、燃料電池はＤＳＳ運転に耐え得るヒートサ
イクル性に優れていることが必要条件となる。Therefore, it is necessary for the fuel cell to have excellent heat cycle properties that can withstand DSS operation.
また、第６図すには燃料電池内部め起動、停止時の各部

池のセパレータ板と、電解質板は夫々伸びδＳおよびδ
Ｅとして発生するが、セパレータ板の伸び量δＳは電解
質板の伸び量δＥよりも大きくなることを示している。Furthermore, Fig. 6 shows changes in elongation of various parts inside the fuel cell during startup and shutdown. As the temperature rises during startup, the separator plate and electrolyte plate of the battery elongate δS and δ, respectively.
This shows that the amount of elongation δS of the separator plate is larger than the amount of elongation δE of the electrolyte plate.
これは、第７図に示すように電解質板よりもセパレータ
板の線膨張係数が大きいことに起因する。第８図は、電
池本体の伸び状況を平面および側面よりみた概略図であ
る。This is due to the fact that the linear expansion coefficient of the separator plate is larger than that of the electrolyte plate, as shown in FIG. FIG. 8 is a schematic view of the elongation of the battery main body viewed from the top and side.

質板１が伸びようとする。従って、セパレータ板４より
も引張強度の弱い電解質板１は電池の起動停止（、昇温
、降りごとに引張、圧縮を受けることになる。, when the temperature rises, the battery expands in four directions from the center, but since the amount of elongation δS of the separator plate is larger than the amount of elongation δE of the electrolyte plate, and the battery is receiving a compressive load from the direction of the arrow in figure F, the positive separator plate 4 The electrolyte plate 1 tries to expand due to the amount of expansion δS. Therefore, the electrolyte plate 1, which has a lower tensile strength than the separator plate 4, is subjected to tension and compression every time the battery is started or stopped (or whenever the temperature rises or falls).
したがって、電解質板として用いられるセラミツク材は
、圧縮強度は高いが引張強度が低いためにヒートサイク
ル時の疲労強度が問題となることがわかった。Therefore, it was found that the ceramic material used as the electrolyte plate has a high compressive strength but a low tensile strength, so that fatigue strength during heat cycling becomes a problem.
そして、電解質板に疲労による割れが発生した場合、ア
ノード側の水素とカソードの空気が混合することになり
水が発生する酸化反応が起こる。When cracks occur in the electrolyte plate due to fatigue, hydrogen on the anode side mixes with air on the cathode, causing an oxidation reaction that generates water.
こうなると発電反応が至しく低下すると共に発熱が生じ
、セパレータ板や電極を腐食させて電池本体の寿命を短
かくすることとなる。If this happens, the power generation reaction will be severely reduced and heat will be generated, corroding the separator plates and electrodes and shortening the life of the battery body.

The thermal stress intensity is increased by providing the

Further, the electrolyte plate 1 may be sintered or not, and electrically insulating seals 9 are inserted at the cell ends located at both ends of the electrolyte plate 1 to prevent carbonate from leaking to the outside. ing. The sealing material 9 and the separator plate 4 are integrated by heating extremely high temperatures through diffusion bonding, laser bonding, or the like. Since the separator plate 4, the electrode pfA 2, and the electrode 3 can be easily integrated under high-temperature reducing conditions, they are bonded in advance. Further, the porous thin plate 8, which is arranged in a grid pattern, has holes only inside the cells other than the seal portion 8a, as shown in FIG. The size of the holes varies in design depending on the strength of the plate and the reaction rate of the cell. The same material as the separator plate 4, such as austenitic stainless steel, is suitable as the material for this porous thin plate, but when the seal portion is to be slid, it is preferable to use ceramic fibers with low heat elongation, such as ceramics. Something like a board is suitable.

In the figure, this device has a porous thin plate 8 positioned below an electrolyte plate 1 and surrounding it. That is, an electrolyte plate 1 made of ceramic is disposed on a porous base plate 8 made of iron or the like. A step is formed near the sealing part of this porous thin plate 8 to connect the sealing material 9, separator 4, and porous thin Fi8.
It has flexibility so that it can follow thermal elongation even when the two are joined together. This porous thin plate 8
It goes without saying that the seal portion does not need to be joined or may have a sliding structure.

て、各部品の密着性がよくなり、電気抵抗が低くなるか
ら電池性能が向上する。According to this example, considering that stress should be avoided since ceramic electrolyte plates are generally hard and weak in tension, the electrolyte plate is supported with a metal material with high high temperature strength to reduce thermal stress strength. In addition, the supporting plate 8 of the electrolyte plate 1 (sealing part 8a
) are sandwiched between separator plates from the outside of the insulating material 9, and they are integrally joined (do not need to be joined) to form one bag. Therefore, the adhesion between each component is improved and electrical resistance is lowered, resulting in improved battery performance.

となる。As explained above, according to the present invention, since the electrolyte plate made of ceramics or the like is supported by a metal material,
Thermal stress strength can be improved without using the electrolyte plate as a strength member, and heat cycle performance can also be improved. In addition, since the supporting plate of the electrolyte plate and the separator plate can be joined together via an insulating means such as an insulating joint to form a single pack, the contact properties are good and the electrical resistance is reduced, which improves the battery performance and improves the cell performance. Easy to assemble and repair.
