Description
第3に、本発明は、上記の燃料電池用電極触媒を備えた固体高分子型燃料電池である。
[触媒の調製]
カーボン担体としてKetjen Black(商標名)を用い、ルテニウムカルボニル、モリブデンカルボニル、イオウをアルゴン中で140℃で加熱し、冷却の後、アセトンで洗浄し、ろ過をする。ろ過物であるRuMoS/C(Ru:Mo:S=5:1:5、60wt%)を350℃で2時間焼成して触媒を調整した。
上記の触媒材料について、EXAFS及びTEMを用いて構造解析を行った。
図2に、EXAFS(Extend X−ray absorption fine structure)によるMoを含むカルコゲナイドの構造解析結果を示す。図3に、TEMによるMoを含むカルコゲナイドのMo−O部分のTEM像(図3(A)、(B))と該Mo−O部分のX線回折像(図3(C))を示す。同様に、図4に、TEMによるMoを含むカルコゲナイドのMo−S部分のTEM像(図4(A)、(B))と該Mo−S部分のX線回折像(図4(C))を示す。
熱処理条件を300℃×1h、350℃×1h、500℃×1h、350℃×2hに変化させて、上記と同様に触媒材料(全てRu:Mo:S=5:1:5)を調整した。
Claims (3)
- ルテニウム(Ru)と、モリブデン(Mo)と、イオウ(S)とを含む燃料電池用電極触媒であって、(Mo−O配位数)/{(Mo−O配位数)+(Mo−S配位数)}=0.44〜0.66であることを特徴とする燃料電池用電極触媒。
- ルテニウム(Ru)と、モリブデン(Mo)と、イオウ(S)とを含む燃料電池用電極触媒において、(Mo−O配位数)/{(Mo−O配位数)+(Mo−S配位数)}=0.44〜0.66であることを触媒性能の指標とすることを特徴とする酸素還元型触媒の性能評価方法。
- 請求項1に記載の燃料電池用電極触媒を備えた固体高分子型燃料電池。
