Description
図1は、本発明の一実施形態に係る吸着ローラ10を軸心Aの方向に見た側面図である。図2は、吸着ローラ10を、軸心Aを含む平面で切断した断面図である。この吸着ローラ10は、長尺帯状の基材91を吸着保持しつつ、水平に延びる軸心A周りに回転することによって、基材9を搬送するローラである。基材91の具体例については、後述する。吸着ローラ10は、複数の吸着孔123を有する円筒状の外周面を有する。製造装置1の稼働時には、図2中に概念的に示した吸引機構17により、複数の吸着孔123に負圧が生じる。帯状の基材91は、当該負圧によって、吸着ローラ10の外周面の一部分に、吸着保持される。なお、吸着ローラ10の直径は、例えば30mm〜1600mmとされる。
吸着ローラ10は、例えば、長尺帯状の電解質膜の表面に、電極層を形成して、固体高分子形燃料電池用の膜・電極接合体を製造する製造装置に用いることができる。当該製造装置では、吸着ローラ10が、長尺帯状の基材91である電解質膜を吸着保持しながら回転する。また、当該製造装置は、吸着ローラ10および塗布部で構成される塗工装置と、乾燥機構とを備える。
以上、本発明の一実施形態について説明したが、本発明は、上記の実施形態に限定されるものではない。
