We are developing a kW scale battery stack. Among these efforts, progress is being made in particular in the development of stacking technology, studies on increasing the size of batteries, and development of battery constituent materials including electrodes. These technologies are interrelated, and once one problem is solved,
The following problems are coming into focus, but one major problem at present is the development of electrode materials, particularly cathode materials, for molten carbonate fuel cells.

現在、カソード材料としては、耐食性および電極性能に

ップの原因となっている。However, this NLO cathode has the problem that it dissolves during use of the battery and precipitates as Ni during electrolysis, which grows and short-circuits between the electrodes, shortening the life of the battery. Moreover, Ni is expensive, which, together with the problem of battery life mentioned above, causes an increase in power generation costs.

か否かという問題がある。There is also active research into using various oxides other than NiO as cathode materials, and there are reports that composite oxides such as perovskite are promising. However, since such oxide electrodes still have insufficient strength, there is a problem as to whether they can withstand scale-up.

発明を完成したのである。As a result of examining various materials with a focus on satisfying the characteristics (1) and (2) in general, we discovered an iron-based alloy composed of the chemical components described below. The present invention was completed based on the finding that when these materials are used as electrode materials, the electrode materials have excellent electrode performance and corrosion resistance.

本発明に係る鉄基合金の合金組成限定理由について述べ
る。Next, the reasons for limiting the alloy composition of the iron-based alloy according to the present invention will be described with reference to the effects of addition of each component on improving the corrosion resistance of the iron-based alloy in a molten carbonate environment (Tables 1 to 4 below).

（第４表参照）。Ｃｒ含有量が１８％を超えると溶融炭
酸塩浴中での耐食性がやや劣化する傾向が認められたた

耐食性は不十分であるが、ＡＩ、Ｓｔの共存によってわ
ずかなＣｒ量でも耐食性が発揮されるので、下限は２％
とした（第４表参照）。It is disclosed that 55-70%) is excellent as an electrode. However, there is a problem in that the amount of Cr in the publication is extremely large, and the inventors of the Wooden Society believe that if an appropriate amount of Al is added to this, sufficient corrosion resistance can be obtained by adding 18% or less of Cr, or even 10% or less of Cr. (See Table 4). If the Cr content exceeds 18%, corrosion resistance in a molten carbonate bath tends to deteriorate slightly, so it is set to 18% or less. In addition, when adding Cr alone, corrosion resistance is insufficient even at 5%, but corrosion resistance is exhibited even with a small amount of Cr due to the coexistence of AI and St, so the lower limit is 2%.
(See Table 4).
Ａｌ：１〜１０％
Ａｌはアルミナ皮膜生成のための主要元素であるが、比
較的少量添加のほうが耐食性が良い。Al: 1-10% Al is a main element for forming an alumina film, but corrosion resistance is better when added in a relatively small amount.
１４％になると溶融塩浴界面部での耐食性が劣化するた

加だけでは界面部の耐食性が十分改善できたとは言えな
いのでＣｒとの複合添加を基本とした。また、１％未溝
の添加では、効果があきらかでないため下限を１％とし
た。At 14%, the corrosion resistance at the molten salt bath interface deteriorates, so the upper limit was set at 10% (see Table 2). However, since it cannot be said that the corrosion resistance of the interface was sufficiently improved by adding Cr alone, the basic method was to add it in combination with Cr. Furthermore, since the effect of adding 1% of ungrooved material is not clear, the lower limit was set to 1%.
Ｓｉ：２〜２０％

した。また２％未満の添加では、効果があきらかでない
ため下限を２％とした。Si: 2-20% Si has the effect of improving corrosion resistance in the gas phase of a molten carbonate environment (see Table 3). However, if it exceeds 20%, the effect disappears, so it was set at 20% or less. However, like AI, adding it alone does not provide sufficient corrosion resistance in the molten carbonate bath and at the interface, so it was added in combination with Cr and AI. Furthermore, since the effect is not obvious when less than 2% is added, the lower limit was set at 2%.
Ｎｉ：７〜２０

はＣｒ、ＡＩ。Ni: 7-20 Ni is basically an undesirable element because it precipitates near the anode as corrosion progresses and shortens battery life, but it has a large effect on improving the mechanical properties of the material and also reduces cathode reaction activity. For improvement, combination with Cr and AI or Cr and AI.

で飽和するのでよ限を２０％とした。It was decided to add 7 to 20% in combination with SL (see Table 4); addition of less than 7% would not improve mechanical properties, and the contribution effect to improvement of mechanical properties would be 20%.
The limit was set at 20% since the saturation occurred at
