The present invention relates to a separator material having good imageability and monolithic properties.

ばならない。Recently, fuel cells have attracted attention due to their good energy efficiency. In particular, high-temperature fuel cells can use electrodes with low catalytic activity, and they can also use impure hydrogen, carbon oxide, methane, or propane as fuel at a certain temperature. It is being actively researched because it can be used as fuel from things that are not present. Among these, molten carbonate fuel cells are seen as promising and are being actively developed. This uses molten carbonate as electrolyte, e.g. Na 2
COn + K z COs, or a mixed carbonate of coco, j, zcoδ, etc. is used, and this is used as a paste by impregnating a porous ceramic plate or by combining the carbonate with magnesia or alumina. However, since molten carbonate is used as an electrolyte at high temperatures and is highly corrosive, the separator material must be highly corrosion resistant.

A corrosion-resistant alloy is disclosed in Japanese Patent No. 229468, which is an iron-chromium-nickel base with aluminum added thereto, and it is described that the sulfidation resistance is improved. However, there is no mention of corrosion against molten carbonates, and this alloy is an iron-chromium-nickel base alloy with less than 1.0% aluminum added, as shown in Figure 1 below. As mentioned above, corrosion resistance to molten carbonates has not been considered in the past, and there is a demand for separator materials with high corrosion resistance.
上に述べた公知技術においては、溶融炭酸塩型燃料電池

善されることを見つけ出し、燃料電池用セパレータ材を
提供せんとするものである。In the known technology mentioned above, there is no separator material that can be satisfactorily used in molten carbonate fuel cells, and in order to solve this drawback, many years of research have been carried out by changing the amount of aluminum added to the iron-chromium-nickel base alloy. However, the present inventors have discovered that the corrosion resistance against molten carbonate can be improved by adding aluminum in an amount of 1% or more, and they aim to provide a separator material for fuel cells.
本発明の燃料電池用セパレータ材は、炭素二０．１５％
以下、けい素：１％以下、マンガン１２％以下、ニッケ
ル：１５〜３５％、クロム：１５〜３５％、アルミニウ
ム：１〜２％を含有する鉄基合金からなるものである。The fuel cell separator material of the present invention has a carbon dioxide content of 0.15%.
Hereinafter, it is made of an iron-based alloy containing 1% or less of silicon, 12% or less of manganese, 15-35% of nickel, 15-35% of chromium, and 1-2% of aluminum.
また、この鉄基合金には極少の不可避不純物が含有され
ていてもよい、また、本発明のセパレータ材は特に溶融
炭酸塩型燃料電池用セパレータに好しいものである。Further, this iron-based alloy may contain very small amounts of unavoidable impurities, and the separator material of the present invention is particularly suitable for separators for molten carbonate fuel cells.
以下１本発明の鉄基合金、即ち鋼の構成成分を上記のよ
うに限定した理由について説明する。炭素はオーステナ
イト形成元素であるが、０．１５％を超えて含有すると
熱間加工性及び耐酸化性を低下させるので、０．１５％
以下が適する。、（尚、％は重量％を示し、他も同様で
ある。）。また。The reason why the constituent components of the iron-based alloy, ie, steel, of the present invention are limited as described above will be explained below. Carbon is an austenite-forming element, but if it is contained in an amount exceeding 0.15%, hot workability and oxidation resistance will be reduced, so 0.15%
The following are suitable. (Note that % indicates weight %, and the same applies to the others.) Also.
けい素は高温強度及び耐酸化性を改善する効果を有する
が、過度に存在すると溶接性及び加工性を阻害するので
１％以下が適する。また、マンガンはオーステナイト形
成元素であるが、耐酸化性をやや悪くするので少い方が
好ましく、通常のステンレス鋼に含有されている程度で
よく、２％以下が適する。また、ニッケルはオーステナ
イト系ステンレス鋼の基本的元素の一つであり、オース
テナイト組織を維持するには下限は１５％がよい。Silicon has the effect of improving high-temperature strength and oxidation resistance, but its presence in excess impedes weldability and workability, so it is preferably 1% or less. Further, although manganese is an austenite-forming element, it slightly deteriorates oxidation resistance, so it is preferable to have less manganese.The content of manganese may be as low as that in ordinary stainless steel, and 2% or less is suitable. Further, nickel is one of the basic elements of austenitic stainless steel, and the lower limit is preferably 15% in order to maintain the austenitic structure.
一方、上限として３５％を超えて含有すると耐硫化性を
劣化させるので好ましくなく、従って１５〜３５％が適
する。また、クロムは溶融塩に対する耐食性の基本成分
であり、最少１５％の含有を必要とし、しかし３５％を
超えて添加しても効果が飽和するので、従って１５〜３
５％が適する。On the other hand, if the content exceeds 35% as the upper limit, it is not preferable because it deteriorates sulfidation resistance, and therefore 15 to 35% is suitable. In addition, chromium is a basic component for corrosion resistance against molten salts, and requires a minimum content of 15%, but the effect is saturated even if it is added in excess of 35%.
5% is suitable.
また、アルミニウムは、その添加量を特定範囲に限定す
るところに本発明の特色があり、１％より少ないと後述
の第１図に示すように溶融炭酸塩に対する耐食性が低下
するので下限は１％がよく、一方多量を添加するとオー
ステナイト組織を不安定にするので上限は２％迄とし、
従って添加量１〜２％が適する。Furthermore, the present invention is characterized by limiting the amount of aluminum added to a specific range; if it is less than 1%, the corrosion resistance against molten carbonate decreases as shown in Figure 1 below, so the lower limit is 1%. On the other hand, adding a large amount will destabilize the austenite structure, so the upper limit is 2%.
Therefore, an addition amount of 1 to 2% is suitable.
また、これにの元素の他に鉄に含まれる不可避不純物１
例えば燐、バナジウム等の極少量が含有されていてもよ
い。In addition to these elements, there are also unavoidable impurities contained in iron.
For example, a very small amount of phosphorus, vanadium, etc. may be contained.
上述の如く本発明の鉄基合金は、アルミニウムを１〜２
％添加することにより溶融炭酸塩に対する耐食性が非常
に向上することを全く新規に見出したもので、良好なセ
パレータ材になし得る。As mentioned above, the iron-based alloy of the present invention contains 1 to 2 aluminum
This is a completely new discovery that the corrosion resistance against molten carbonate is greatly improved by adding % of molten carbonate, and it can be made into a good separator material.
以下、実施例について説明する。Examples will be described below.

りも耐食性が大きいことが明らかである。Manganese, nickel, chromium, and aluminum were added to give the composition percentages of each element as shown in Table 1. Also, for comparison, 5US3LO which does not add any aluminum
No. 3, and an iron-based alloy to which 1.0% or less of aluminum was added were tested as samples. In the corrosion test, LizC○8: to 2CO3 = 62:38 (mole ratio) was used as the carbonate, the carbonate was melted at a temperature of 750°C and applied to the sample alloy, and the gas composition C○2 was used as the atmospheric gas. : Air = 30 near 0 gas is flowed at a flow rate of 250cc/N resistance,
A corrosion test was conducted for 480 hours.Table 1 (Composition %) The test results are shown in FIG. Test Nn3. Aluminum like Nα4 1.
When 0% or more of aluminum is added, the thinning thickness decreases to about 14 μm or less, and especially when 1.56% of aluminum with test Nα4 is added, the thinning thickness decreases significantly, indicating that corrosion resistance is greatly improved. There is. In addition, alloys with no aluminum added in test Nnl and aluminum in test NG2
．． In the case of alloys with less than 0% thickness, the thickness reduction is approximately 20~3
It is clear that alloys in which 1% or more of aluminum is added to iron-based alloys have excellent corrosion resistance against molten carbonate. Therefore, it is clear that the iron-based alloy of the present invention has greater corrosion resistance than 5US310S and 5US316L currently used as separators for molten carbonate fuel cells.
