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.
[発明が解決しようとする問題点]
現在、カソード材料としては、耐食性および電極性能に

、電池寿命を短くするという問題がある。しかもNiは
高価なため前記電池寿命の問題と相俟って発電コストア
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.
次に溶融炭酸塩環境中での鉄基合金の耐食性改善におよ
ぼす各成分の添加効果(後記第1〜4表)を参照しつつ
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).
Cr:2〜18%
Fe−Cr系合金の耐食性はCr含有量が増加するほど
向上する(第1表参照)。特開昭58−155862に
もフェロクロム<cr含有i。Cr: 2-18% The corrosion resistance of Fe-Cr alloys improves as the Cr content increases (see Table 1). JP-A-58-155862 also describes ferrochrome <cr containing i.
55〜70%)が電極として優れていることが、開示さ
れている。しかし当該公報中のCr量は非常に多いとい
う問題があり、木発明者等は、これに適量のAlを添加
すれば、18%以下さらには10%以下のCr添加によ
っても十分な耐食性が得られることを見出したのである
(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
め18%以下とした。また、Cr単独添加では5%でも
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
め上限を10%とした(第2表参照)。ただし、単独添
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%
Siは溶融炭酸塩環境の気相部での耐食性を改善する効
果がある(第3表参照)。しかし、20%を超えるとそ
の効果もなくなるので20%以下とした。ただし、これ
もAIと同様に単独添加では溶融炭酸塩浴中および界面
部の耐食性が十分でないためCr、AIとの複合添加と
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
Niは腐食の進行によってアノード近辺で析出し、電池
寿命を短くするため基本的には好ましくない元素である
が、材料の機械的性買改善効果が大きく、且つカソード
反応活性を向上させるため、Cr、AIとの複合あるい
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.
SLとの複合の下で7〜20%添加することとした(第
4表参照)、7%未満の添加では機械的性質の改善がで
きず、また機械的性質の改善に対する寄与効果は20%
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
