[Industrial Field of Application] The present invention relates to a separator material for molten carbonate fuel cells that has good corrosion resistance against molten carbonate. [Prior Art] Recently, fuel cells have attracted attention because of their good energy efficiency. In particular, high-temperature fuel cells can use electrodes with low catalytic activity, and they can also be used to store impure hydrogen, carbon monoxide, methane, propane, etc. at room temperature. It is being actively researched because it can be used as fuel for things that cannot be used as fuel. Among these, molten carbonate fuel cells are seen as promising and are being actively developed. This uses molten carbonates as electrolytes, e.g. Na 2 CO 3 , K 2
A mixed carbonate containing CO 3 or Li 2 CO 3 or the like is used, and this is used as a paste by impregnating a porous ceramic plate or by mixing 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. Conventionally, stainless steel, such as SUS316L and SUS310S, has been used as a separator material.
Corrosion resistance is not satisfied. Also, JP-A-59-
Publication No. 229468 discloses a corrosion-resistant alloy, which is made by adding aluminum to an iron-chromium-nickel-based alloy, and is said to improve sulfidation resistance. There is no mention of corrosion. Furthermore, this alloy has aluminum added in an amount of 1.0% or less based on the iron-chromium-nickel base, and has low corrosion resistance against molten carbonate, as seen in FIG. 1, which will be described later. As mentioned above, conventionally no consideration has been given to corrosion resistance against molten carbonates, and there is a demand for separator materials that have high corrosion resistance against molten carbonates. [Problems to be Solved by the Invention] In the above-mentioned known technology, there is no separator material that can be used satisfactorily in molten carbonate fuel cells, and the present inventors have developed an iron-based material to solve this drawback. After many years of research with varying amounts of aluminum added to chromium-nickel-based alloys, we found that the amount of aluminum added was 1.05
It has been discovered that the corrosion resistance against molten carbonate can be improved by adding ~2%, and the aim is to provide a separator material for a molten carbonate fuel cell. [Means for Solving the Problems] The separator material for a molten carbonate fuel cell of the present invention contains, by weight, carbon: 0.15% or less, silicon: 1% or less, manganese: 2% or less, and nickel: 15-15%. 35%,
It contains chromium: 15-35%, aluminum: 1.05-2%, and the remainder consists of iron and inevitable impurities. Hereinafter, the reason why the constituent components of the separator material for a molten carbonate fuel cell of the present invention are limited as described above will be explained. 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 the carbon content should be 0.15% or less. (Incidentally, % indicates weight %, and the same applies to others.)
Further, silicon has the effect of improving high temperature strength and oxidation resistance, but if present in excess, it impairs weldability and workability, so it is limited to 1% or less. In addition, manganese is an austenite-forming element, but since it slightly deteriorates oxidation resistance, it is preferable to have a small amount.The content of manganese in ordinary stainless steel may be as low as 2%.
The following shall apply. Furthermore, nickel is one of the basic elements of austenitic stainless steel, and the lower limit is 15% to maintain the austenitic structure.
On the other hand, if the nickel content exceeds the upper limit of 35%, it is not preferable because it deteriorates the sulfidation resistance, and therefore the nickel content is set at 15 to 35%. Also,
Chromium is a basic component for corrosion resistance against molten carbonates, and requires a minimum content of 15%, but the effect will be saturated even if it is added in excess of 35%.
~35%. Furthermore, the present invention is characterized by limiting the amount of aluminum added within a specific range; if it is less than 1%, the corrosion resistance against molten carbonate will decrease as shown in Figure 1 below, so the lower limit is
The upper limit is set at 1.05%, but the upper limit is set at 2% because adding too much will destabilize the austenite structure.
Therefore, the amount of aluminum added should be 1.05 to 2%. Further, in addition to these elements, a very small amount of inevitable impurities contained in iron, such as phosphorus and vanadium, may be contained. As mentioned above, the separator material for molten carbonate fuel cells of the present invention has a completely new feature that the corrosion resistance against molten carbonate is greatly improved by adding 1.05 to 2% aluminum to the Fe-Cr-Ni base alloy. It is based on what we found. Examples will be described below. [Example] As a sample of the separator material for a molten carbonate fuel cell of the present invention, an iron-based alloy was produced in the following manner. Carbon, silicon, manganese, nickel, chromium, and aluminum were added to iron, and the composition of each element was determined as shown in Table 1 (% by weight). Also, for comparison, no aluminum is added at all.
SUS310S (Sample No. 1 in Table 1) and an iron-based alloy to which 0.53% aluminum was added (Sample No. 2 in Table 1) were also tested as samples. In the corrosion test, Li 2 CO 3 :K 2 CO 3 = 62:38 (molar ratio) was used as the carbonate, and the carbonate was melted at a temperature of 750°C.
Apply it to the sample alloy and check the gas composition as an atmospheric gas.
A corrosion test was conducted for 100 hours by flowing a CO 2 :air ratio of 30:70 gas at a flow rate of 250 c.c./min.

パレータとして有効である。[Table] The test results are shown in Figure 1, which shows the relationship between the aluminum addition composition on the horizontal axis and the thickness of thinning due to corrosion on the vertical axis. When aluminum is added in an amount of 1.05 to 2%, as in samples No. 3 and No. 4 of the present invention, the thickness decreases to approximately
Reduced to below 14μm, especially aluminum by 1.56%
In the case of sample No. 4 in which the addition was made, the decrease in thickness was remarkable, indicating that the corrosion resistance was significantly improved.
In addition, in the case of sample No. 1, an alloy with no added aluminum, and sample No. 2, an alloy with 1.0% or less of aluminum added, the thickness reduction is approximately 20 to 20%.
It is in the 30μm range and is large. From this, it is clear that an alloy in which 1.05% to 2% aluminum is added to an iron-based alloy has excellent corrosion resistance against molten carbonate. Therefore, it is clear that the iron-based alloy of the present invention has greater corrosion resistance than SUS310S and SUS316L currently used as separator materials for molten carbonate fuel cells. [Effect of the invention] The iron described in the claims of the present invention has carbon,
The separator material for molten carbonate fuel cells, which is made by adding predetermined amounts of silicon, manganese, nickel, and chromium and especially 1.05 to 2% aluminum, with the balance being iron and unavoidable impurities, has good corrosion resistance against molten carbonate. This material is effective as a separator for molten carbonate fuel cells.
