Description
図1は、燃料電池スタック(燃料電池)10の要部を断面視した図である。図1に示すように、燃料電池スタック10には、基本単位であるセル(単電池)1が複数積層されている。各セル1は、酸化剤ガス(例えば空気)と、燃料ガス(例えば水素)と、の電気化学反応により起電力を発生する固体高分子型燃料電池である。セル1は、MEGA2と、MEGA2を区画するように、MEGA2に接触するセパレータ(燃料電池用セパレータ)3とを備えている。なお、本実施形態では、MEGA2は、一対のセパレータ3、3により、挟持されている。
図2は、セパレータの製造工程の概略フローを示した図である。また、図3及び図4はそれぞれ、セパレータの製造に用いる金型の拡大斜視断面図及び要部拡大断面図であり、図5は、セパレータの製造途中の様子を示す拡大断面図である。
