ター用部材としてカーボン板が用いられており、カーボ
ン板を可能な限り薄く加工して上記りん酸型燃料電池用
セルのセパレーターとして使用していた。In response to these demands for properties, carbon plates have been conventionally used as separator members, and carbon plates have been processed to be as thin as possible and used as separators in the above-mentioned phosphoric acid fuel cells.
〔発明が解決しようとする問題点〕
上記カーボン板は、りん酸型燃料電池用セパレーターと
して優れた部材であるものの、もろい材料であるため、
カーボン板を薄く加工することが難しく、また取扱い中
に割れやすいという欠点があった。[Problems to be solved by the invention] Although the above carbon plate is an excellent member as a separator for phosphoric acid fuel cells, it is a brittle material, so
It was difficult to process the carbon plate to be thin, and it also had the disadvantage that it was easily broken during handling.
ところが、一方では、りん酸型燃料電池には、第１図に

に対する薄肉化の要求が強く、セパレーターにも同じ要
求があるが、カーボン板では割れやすいという問題から
厚さは１０程度が限界であった。However, on the other hand, since a phosphoric acid fuel cell uses a stacked cell containing, for example, 200 layers of carbon plate separators 1 as shown in FIG. If the size is large, the cynic acid fuel cell will be large, so there is a strong demand for thinner walls for each part that makes up the cell, and the same demand is also placed on the separator, but due to the problem that carbon plates break easily. The maximum thickness was about 10 mm.

Contains atomic atoms, Ta: 1 to 10 atoms, 8%Si 1 m or 2 types: 0.1 to 7.0 atoms, P-1-B-) Si: 15 to 23 atoms. The inventors have found that an excellent separator for phosphoric acid fuel cells can be obtained by manufacturing an amorphous alloy consisting of: Ni and unavoidable impurities.
この発明は、かかる知見にもとづいてなされたものであ
って、上記（１）〜（４）の合金で作製したシん酸型燃
料電池用セパレーターに特徴を有するものである。The present invention was made based on this knowledge, and is characterized by a separator for a cynic acid fuel cell made of the alloys (1) to (4) above.
つぎに、この発明のりん酸型燃料電池用セパレーターに
用いるアモルファス合金の成分組成を上記の如く限定し
た理由について述べる。Next, the reason why the composition of the amorphous alloy used in the separator for a phosphoric acid fuel cell of the present invention is limited as described above will be described.
Ｃｒ。Cr.
Ｃｒは、不動態皮膜を形成する元素であって、高温濃り
ん酸のような非酸化性の酸中で、特にその特性を発揮す
る元素であるが、その含有量が１０原子チ未満では、高
温濃りん酸中での耐′食性が不十分であり、また、３０
原子チを越えて含有すると、アモルファス形成能が低下
する。Cr is an element that forms a passive film and exhibits its properties particularly in non-oxidizing acids such as high-temperature concentrated phosphoric acid, but when its content is less than 10 atoms, The corrosion resistance in high-temperature concentrated phosphoric acid is insufficient, and
If the content exceeds 1 atom, the ability to form an amorphous layer decreases.
したがって、 ｃｒ含有量の範囲は、１０〜３０原子チ
と定めた。Therefore, the range of cr content was determined to be 10 to 30 atoms.
Ｐには、 Ｎｉと共存してアモルファス構造を形成する
のに有効な作用がありｓＣｒを主成分とする保護皮膜の
形成を促す作用があるが、その含有量が１５原子−未満
では、アモルファス形成能が低下し、したがって耐食性
も低下する。一方、その含有量が２３原子チを越えて含
有すると、高温濃りん酸中の環境で保護性の低いりん酸
塩皮膜が、Ｐが酸化されて生じるので好ましくない。P has an effective effect in coexisting with Ni to form an amorphous structure and promotes the formation of a protective film mainly composed of sCr, but if its content is less than 15 atoms, amorphous structure may be formed. performance and therefore corrosion resistance. On the other hand, if the content exceeds 23 atoms, P is undesirably oxidized, resulting in a phosphate film with low protective properties in the environment of high-temperature concentrated phosphoric acid.
したがって、Ｐの含有量は、１５〜２３原子チと定めた
。Therefore, the content of P was determined to be 15 to 23 atoms.
Ｔａ。Ta.
Ｔａは、保護皮膜を形成して耐食性を担う元素であるが
、Ｐ％あるいは％ＰとＢおよびＳｉの少なくとも一種と
共存する場合は、ＰがＴａによる保護皮膜の形成を加速
するため、 Ｔａが１原子チでも保護皮膜が形成される
が、 Ｔａが１０原子チ゛を越えてもアモルファス形成
能が落ちて効果がない。Ta is an element responsible for corrosion resistance by forming a protective film, but when P% or %P coexists with at least one of B and Si, Ta accelerates the formation of a protective film by Ta. A protective film can be formed even with one atom of Ta, but if Ta exceeds ten atoms, the ability to form an amorphous layer decreases and there is no effect.
したがって、 Ｔａの含有量を１〜１０原子チと定めた
。Therefore, the Ta content was determined to be 1 to 10 atoms.
Ｂ、Ｓｉ
ＢおよヒＳ１成分も、Ｎｌと共存してアモルファス構造
を形成するのに有効な成分であり、Ｐと置換することが
できる元素であるが、アモルファス形成能を高めるため
には、Ｂ、Ｓｉの１種または２種は最低０．１原子チは
必要であり、また保護皮膜の形成を促すＰの作用を低下
させないためにはＢ。B, Si B, and S1 components are also effective components for forming an amorphous structure in coexistence with Nl, and are elements that can be substituted for P, but in order to enhance the amorphous formation ability, One or both of B and Si is required in an amount of at least 0.1 atom, and B in order not to reduce the effect of P that promotes the formation of a protective film.
Ｓｌの１種または２種は７原子チを越えて含有してはな
らない。One or two types of Sl must not contain more than 7 atoms.
したがって、Ｂ、Ｓｉの１＄１または２種の含有量を０
．１〜７．０原子チと定めた。Therefore, if the content of 1$1 or 2 of B and Si is 0
．． It was determined to be 1 to 7.0 atoms.
Ｐ−１−Ｂ−１−８ｉ、
ＢおよびＳｉ成分は、上述のようにＮ１と共存してアモ
ルファス構造を形成するのに有効であるが。P-1-B-1-8i, B and Si components are effective in coexisting with N1 to form an amorphous structure as described above.
Ｐの一部と置換することによシ一層アモルファス形成能
を高める作用もある。ところが、ＰとＢと８１の合計が
１５原子チ未満では、アモルファス形成能が低下し耐食
性も低下する。一方、ＰとＢと８１の合計が２３原子チ
を越えて含有すると保護皮膜の形成能が悪く耐食性が低
下する。したがって、ＰとＢ 、！：ｓｉの合計は、１
５〜２３原子チと定めた。Substituting a part of P also has the effect of further enhancing the amorphous formation ability. However, if the total of P, B, and 81 is less than 15 atoms, the amorphous formation ability decreases and the corrosion resistance also decreases. On the other hand, if the total of P, B, and 81 exceeds 23 atoms, the ability to form a protective film will be poor and the corrosion resistance will be reduced. Therefore, P and B,! :The total of si is 1
It was set as 5 to 23 atoms.
