【発明の詳細な説明】 〔産業上の利用分野〕 本発明は溶融炭酸塩型燃料電池に係り、特に電解質保持
力を向上させた電解質板の製造方法に関する。Description: TECHNICAL FIELD The present invention relates to a molten carbonate fuel cell, and more particularly to a method for producing an electrolyte plate with improved electrolyte retention.
燃料電池の一般的構造は第４図のようになっており、電
解質板１の上下には電解質板を挟むように２種の電極
（アノード２及びカソード３）が設けられている。アノ
ード２には燃料ガスを供給する燃料流路溝５及び、カソ
ード３には酸化剤ガスを供給する酸化剤流路溝６を有す
るセパレータ４が積層されている。The general structure of the fuel cell is as shown in FIG. 4, and two kinds of electrodes (anode 2 and cathode 3) are provided above and below the electrolyte plate 1 so as to sandwich the electrolyte plate. A separator 4 having a fuel flow channel 5 for supplying a fuel gas to the anode 2 and an oxidant flow channel 6 for supplying an oxidant gas is laminated on the cathode 3.
これ等の電極は数十ミクロンの微細孔を有し、ガスが拡
散可能となっている。These electrodes have fine pores of several tens of microns and are capable of diffusing gas.
溶融炭酸塩型燃料電池に使用される電解質は、Li2CO3、
K2CO3、NaCO3等の混合物であり、その中でも一般的なの
はLi2CO3：K2CO3＝62：38のモル比で融点が約490℃のも
のである。The electrolyte used in the molten carbonate fuel cell is Li 2 CO 3 ,
It is a mixture of K 2 CO 3 , NaCO 3, etc., and among them, a common one has a molar ratio of Li 2 CO 3 : K 2 CO 3 = 62: 38 and a melting point of about 490 ° C.
従ってこの電解質は室温では固体であり、650℃の電池
運転温度に於いては溶融状態となっている。Therefore, this electrolyte is a solid at room temperature and is in a molten state at a battery operating temperature of 650 ° C.
電解質板１は、電解質とその電解質を保持するマトリッ
クスからなり、マトリックスは電解質を保持した状態に
おいて、燃料ガスと酸化剤ガスを分離し、さらに電子の
不導体でCO3 2-イオンの良導体でなければならない。The electrolyte plate 1 is composed of an electrolyte and a matrix that holds the electrolyte. The matrix must separate the fuel gas and the oxidizer gas while holding the electrolyte, and must be a nonconductor of electrons and a good conductor of CO 3 2− ions. I have to.
そのため、マトリックスは溶融塩に対して安定であり、
かつ電気絶縁性の高い物質からなる多孔体で構成されて
いる。Therefore, the matrix is stable to molten salt,
In addition, it is composed of a porous body made of a material having high electric insulation.
例えば、アルミン酸リチウム、チタン酸ストロンチウ
ム、ジルコン酸ストロンチウム等は上記条件を満足する
ため、マトリックス材料として好適である。For example, lithium aluminate, strontium titanate, strontium zirconate, and the like satisfy the above conditions, and are therefore suitable as matrix materials.
燃料ガスと酸化剤ガスとの混合を防ぐのは、基本的には
電解質の毛管力によっており、燃料ガス圧力と酸化剤ガ
ス圧力の差圧に耐えるためには、マトリクッス中の細孔
径を出来るだけ小さくしなければならない。また、細孔
径が小さい程、電解質の蒸気圧を下げる効果があり、電
解質の消失量を抑える意味からも、細孔径が小さい方が
好ましい。さらに組立時に割れたりしないようにハンド
リング性が良くなければならない。It is basically the capillary force of the electrolyte that prevents the mixing of fuel gas and oxidant gas. In order to withstand the differential pressure between fuel gas pressure and oxidant gas pressure, the pore size in the matrix should be as small as possible. Must be small. Further, the smaller the pore diameter, the more effectively the vapor pressure of the electrolyte is lowered, and the smaller pore diameter is preferable also from the viewpoint of suppressing the loss of the electrolyte. In addition, it must be easy to handle so that it will not crack during assembly.
それらの条件を満足するものとして、例えば特開昭58-7

スが知られている。As those satisfying those conditions, for example, JP-A-58-7
As disclosed in Japanese Patent No. 1564, 1 as a matrix material
There is known a composite matrix in which a matrix tape made of ceramic fine particles of μm or less, ceramic particles of 25 μm or more and a plastic binder is combined with a bubble barrier sheet made of an electrode material metal and having a pore size of 1 μm or less.

とである。As described above, the conditions required for the matrix are (1) stable to the electrolyte, (2) having a large number of fine pores, (3) excellent in handling property such as no damage during assembly, and ( 4) High porosity [= (volume of pores contained in matrix) / (total volume of matrix)].
特開昭58-71564号に提案されたマトリクッステープは、

きな影響を受けてしまう。さらに気孔率が低いと電解質
中の炭酸イオンの伝導抵抗も大きくなる。また、泡障壁
は金属であるため、マトリクッスと組合せると、熱膨張
率の違いから温度変化によって大きな応力が発生し、割
れが生じるという問題も有している。The matrix tape proposed in JP-A-58-71564 is
Since the mixture of large and small ceramic particles is used, the above requirements (1) to (3) are satisfied, but the porosity of requirement (4) cannot be increased. As a result, the amount of electrolyte retained becomes small, and even if a small amount of the electrolyte is lost due to evaporation or the like, it is greatly affected. Further, when the porosity is low, the conduction resistance of carbonate ions in the electrolyte also becomes large. Further, since the bubble barrier is made of metal, when combined with the matrix, there is a problem that a large stress is generated due to a temperature change due to a difference in coefficient of thermal expansion and a crack is generated.
本発明の目的は、ハンドリング性を損なうことなく微細
孔かつ高気孔率とできる溶融炭酸塩型燃料電池用電解質
板の製造方法を提供することにある。An object of the present invention is to provide a method for producing an electrolyte plate for a molten carbonate fuel cell, which can have fine pores and high porosity without impairing handleability.

解質板を製造することによって達成される。The purpose is to hydrolyze a metal alkoxide by using a cloth or felt made of ceramic fibers or a long sheet made of a mixture of the cloth or felt and ceramics powder and filled with an alkali metal carbonate in the internal pores. Slurry sol obtained by deflocculating the metal hydroxide produced by the method is formed into a thin plate, then dried and gelled, and sandwiched between two flexible long sheets having fine pores and This is achieved by pressing the long sheet with a pressure roll to perform pressure bonding, and then subjecting the metal hydroxide to a heat dehydration treatment to produce an electrolyte plate.
通常、セラミックス粒子でマトリクッスを形成すると気
孔率は30％が限度である。これでは充分な炭酸イオンの
伝導率が得られず電池性能が高くならない。Usually, when forming matrix with ceramic particles, the porosity is limited to 30%. With this, sufficient conductivity of carbonate ions cannot be obtained, and the battery performance is not improved.

で、電解質板が外部へ流れ出すことがない。In the present invention, a cloth or felt made of ceramic fibers or a mixture thereof with a ceramic powder is used as the electrolyte holding material to form the pores, so that a sufficient amount of the electrolyte is held. Since the sheets made of ceramic particles are provided on both sides of the sheet of cloth or the like holding the electrolyte, the electrolyte plate does not flow out.
以下、本発明を実施例に基づき更に説明する。 Hereinafter, the present invention will be further described based on examples.

合アルキシド Li[Al[OCH(CH3)CH2CH3]4]を作り、それに水H2Oを加え、
水酸化物LiAl(OH)4を沈澱させ、それに酢酸CH3COOHを加
え解膠しゾル化した。First, lithium butoxide Li [OCH (CH 3 ) CH 2 CH 3 ] and aluminum butoxide Al [OCH (CH 3 ) CH 2 CH 3 ] 3 are mixed, and mixed alkoxide Li [Al [OCH (CH 3 ) CH 2 Make CH 3 ] 4 ], add water H 2 O to it,
Hydroxide LiAl (OH) 4 was precipitated, and CH 3 COOH acetate was added thereto to peptize it to form a sol.
このゾル中の粒子径は0.01〜0.1μｍ程度であり、これ
を第１図に示すようにして、シート状に整形し乾燥させ
ゲル化すれば0.1μｍ以下の微細孔を有する可撓性のゲ
ルシートができる。The particle size in this sol is about 0.01 to 0.1 μm. As shown in FIG. 1, a flexible gel sheet having fine pores of 0.1 μm or less if shaped into a sheet, dried and gelled. You can
すなわち、前記LiAl(OH)4のスラリー状ゾル７をベルト
コンベア11の上に流し、ゾルのシート８を作り、ヒータ

損しやすくなる。通常0.1mm程度のものが用いられる。
このゲルシート10は板厚0.1mmと薄いため、可撓性に富
み容易にロールに巻きとることができる。That is, the LiAl (OH) 4 slurry sol 7 is poured onto a belt conveyor 11 to form a sol sheet 8, which is heated by a heater 9 to be dried and gelled to form a gel sheet 10.
Take up with roll 12. It is desirable that the sheet has a smaller thickness because the ionic conduction resistance becomes smaller, but if the sheet is too thin, it is easily damaged. Usually, a diameter of about 0.1 mm is used.
Since this gel sheet 10 is thin with a plate thickness of 0.1 mm, it is highly flexible and can be easily wound into a roll.
第２図に示すように、アルミナ繊維で作られた布16に電
解質スラリー17を添着し、それをサンドイッチ状に挟む
ように前記のアルコキシド法で作ったゲルシート15を圧
着ロール18で加圧して圧着し複合電解質板19を作製し
た。As shown in FIG. 2, the electrolyte slurry 17 is attached to the cloth 16 made of alumina fiber, and the gel sheet 15 made by the above-mentioned alkoxide method is pressed by the pressure roll 18 so as to sandwich it in the sandwich shape. Then, a composite electrolyte plate 19 was produced.

Alumina Fiber Cloth 16 Electrolyte Slurry in the interfiber gap
17 is held, and a gel sheet 15 is attached so as to sandwich it. This electrolyte plate is the operating temperature of the battery
If the temperature is raised to 650 ℃, LiA in the gel sheet
l (OH) 4 is dehydrated into lithium aluminate LiAlO 2 ,
It becomes a ceramics porous body having fine pores of 0.1 μm or less. In addition, this heating step may be performed by incorporating an unheated electrolyte plate into the battery and performing the heating process.
この方法で作られた電解質板は、その主成分がアルミナ

ウムと反応してアルミン酸リチウムとなり二酸化炭素を
発生するが、それによって気孔率が多少増加するだけで
ほとんど悪影響が無い。The electrolyte plate produced by this method has a large porosity because it has a large porosity because its main component is alumina fiber, so that it retains a large amount of electrolyte and also has a low ionic resistance. The alumina fiber 16 is not stable to the electrolyte and reacts with lithium carbonate to form lithium aluminate to generate carbon dioxide. However, this slightly increases the porosity and has almost no adverse effect.
またゲルシート15は、微細孔であるため気孔率は小さい

0.1μｍ以下の細孔を有するアルミン酸リチウムの板と
なるため、燃料ガスと酸化剤ガスとの差圧による混合を
充分に防止できる。従ってゲルシート15の間に挟む多孔
体は細孔径が大きくても良い。Further, the gel sheet 15 has small porosity because it is fine pores, but since it is a thin plate of 0.1 mm or less, ionic resistance hardly increases. Further, this gel sheet 15 is thin and has low strength, but since it is made of the same material as the alumina fiber cloth 16 sandwiched between them, no stress is generated due to the difference in thermal expansion. The strength of the electrolyte plate is taken up by the alumina fiber cloth 16 in the central portion, and there is no problem in handling. Gel sheet 15
Since the plate is made of lithium aluminate having pores of 0.1 μm or less, it is possible to sufficiently prevent mixing due to the differential pressure between the fuel gas and the oxidant gas. Therefore, the porous body sandwiched between the gel sheets 15 may have a large pore size.
以上ではアルミナ繊維の布16を電解質保持材としたが、
布でなくても気孔率が大きいものならアルミナのフェル
トや、アルミナの長繊維とアルミナ粉末の混合物であっ
ても良い。In the above, the alumina fiber cloth 16 is used as the electrolyte holding material,
Alumina felt or a mixture of alumina long fibers and alumina powder may be used as long as it has a high porosity even if it is not a cloth.

いった電解質マトリクッスに好適な材料の微細孔ゲルシ
ートが得られる。In this example, lithium aluminate was described as the ceramic material, but if the type of alkoxide is changed, a microporous gel sheet of a material suitable for the electrolyte matrix such as strontium titanate or strontium zirconate can be obtained.

It can be manufactured uniformly in a process and in large quantities.
