Abstract
【解決手段】本発明の燃料電池用集電体は、伝導性物質及び炭化珪素を含み、前記伝導性物質は前記炭化珪素の内部に位置することを特徴とする。
【選択図】 図1
Description
本発明の燃料電池用集電体は、燃料電池に含まれた単位セルの分離板、燃料電池の単位セル同士の間に位置する連結材、又は燃料電池におけるスタックの電気を集電する集電体を意味する。
硬化したフェノール樹脂が充填された炭素繊維を900℃で炭化させて多孔性炭素複合体を形成させた。前記多孔性炭素複合体上にシリコンを位置させ、これを1620℃で熱処理した。前記熱処理の結果、一部のシリコンは炭素繊維と反応して炭化珪素を形成し、一部のシリコンはそのまま炭化珪素に染み込み、一部の炭素繊維はシリコンと反応せずにそのまま残っている。これにより、表面が炭化珪素であり、内部にはシリコンと炭素繊維が位置する炭化珪素複合体を形成した。
常温でデジタルマルチメーター(製造社:fluke、モデル名:233)を用いて前記実施例1及び比較例1の燃料電池用集電体の抵抗を測定した。
2 伝導性物質
