Abstract
A first metal separator of a power generation cell includes boss pairs. Each of the boss pairs includes two first bosses provided adjacent to a hole and adjacent to each other between a passage bead and an oxygen-containing gas flow field. A gap facing the hole is formed between the two first bosses. The second metal separator includes one second boss facing the boss pair through a resin film. The second boss extends over the two first bosses as viewed in a separator thickness direction.
