Abstract

PURPOSE:To prevent molten carbonate from touching the manifolds and the manifold seal contact surfaces of the separators thus to prevent corrosion of the seal part by using a material mainly composed of boracic acid system glass as a seal body between the manifolds and the sides of a fuel cell proper. CONSTITUTION:A fuel cell proper 1 comprises laminated plural unit cells 3 through separators 4 between the end plates 2a and 2b. Felts 7a-7d formed of angular and annular alumina fibers are stuck together to the flange parts of manifolds 8a-8d respectively while boracic acid glass powder is applied to the surfaces of said felts 7a-7d. The manifolds 8a-8d provided with said bodies are fitted to each side of the fuel cell proper 1 for forming the fuel cell. The thus constituted fuel cell generates no corrosion even when its temperature is raised up to 650 deg.C while being operated for 200hr.

電極反応を起こさせるもので、リン酸型、固体電解質型
等の他の燃料電池に比べ、電極反応か起り易く、発電熱
効率が高いという利点を有する。Molten carbonate fuel cells, which have been under development in recent years, use an electrolyte made of alkali carbonate that is molten at high temperatures.
It causes an electrode reaction, and compared to other fuel cells such as phosphoric acid type and solid electrolyte type, it has the advantage that electrode reaction occurs more easily and heat generation efficiency is higher.

このような溶融炭酸塩型燃料電池で高出力の発電プラン

ら複数の単位電池を直列に積層して燃料電池本体を構成
し、各単位電池の加算出力を得る必要がある。このため
、通常、この種の燃料電池は次のように構成される。In order to construct a high-output power generation plant using such a molten carbonate fuel cell, since the output of the unit cell is weak, the fuel cell body is constructed by stacking multiple unit cells in series, and each unit It is necessary to obtain the additive output of the battery. For this reason, this type of fuel cell is usually configured as follows.

すなわち、各単位電池は一対の多孔質電極板と、これら

各電極板への反応ガスの通路を提供する機能とを兼ね備
えた導電性のセパレータを介して積層される。That is, each unit cell is composed of a pair of porous electrode plates and an electrolyte layer made of carbonate interposed between them. These unit cells are stacked with conductive separators interposed therebetween, which have both the function of electrical connection between the unit cells and the function of providing a passage for reactant gas to each electrode plate.

ニホールドからガスを排出する構成をとる。The four sides of the fuel cell main body configured in this way are as follows:
A manifold with the function of distributing and collecting reaction gases is used. Oxidizing gas is then supplied to one of these manifolds and fuel gas is supplied to the adjacent manifold, and both gases contribute to electrode reactions inside the fuel cell main body to obtain DC output, and then The structure is such that the gas is exhausted from the manifold.

各単位電池の周縁部には、両支店ガスが燃料電池本体の
内部の意図しない側へ漏洩、混入するのを防止するため

考えられていた。Incidentally, it is necessary to form a seal between the above-mentioned manifold and the side surface of the fuel cell main body to prevent leakage of the reactant gas. Conventionally, it has been considered to use zirconia felt impregnated with molten carbonate as this sealing body.

下をもたらすという問題がある。However, with such a sealing body, the flange portion of the manifold facing the fuel cell main body and the four side corner portions of the separator are always in contact with the molten carbonate serving as a wet seal. As is well known, the operating temperature is 600℃~
Since carbonate in a molten state at 700°C is corrosive, the parts that come into contact with the molten carbonate as described above will corrode with long-term use of the fuel cell, causing a problem in that the corrosion loss will cause a decrease in airtightness. be.

まうという問題があった。In addition, corrosion products with electronic conductivity that occur along with this may cause short circuits between unit batteries or between unit batteries and manifolds, and leakage current may flow between unit batteries through molten carbonate that has ionic conductivity. In addition to deteriorating battery performance, there is a problem in that the leakage current causes the electrolyte to move across the unit cells.

を用いたことを特徴としている。The present invention comprises a fuel cell main body formed by stacking a plurality of unit cells with separators interposed therebetween, and a manifold that is applied to each side of the fuel cell main body and allows a reaction gas to flow through the gas flow path of each of the unit cells. The molten carbonate fuel cell is characterized in that a material containing boric acid glass as a main component is used as a seal between the manifold and the side surface of the fuel cell main body.

に防止することができる。Boric acid glass becomes molten at a temperature lower than the operating temperature of the fuel cell, and also has the property of repelling molten carbonate and not mixing with it. During this period, a wet seal is formed only by the molten boric acid glass. Therefore, this boric acid glass can prevent molten carbonate from coming into contact with the manifold seal contact surface of the manifold or separator, and can extremely effectively prevent corrosion of the seal portion.
