Fuel cell

摘要

A fuel cell unit configuring a fuel cell is provided with a first separator, a first electrolyte film/electrode body, a second separator, a second electrolyte film/electrode body, and a third separator. Resin guide members are provided on the outer periphery of the first separator, the second separator, and the third separator. The resin guide members have outer peripheral ends which protrude outwards, and in the aforementioned resin guide members are formed concave reliefs which are spaced inwards from the aforementioned outer peripheral ends.
