Abstract
A first metal separator of a power generation cell includes an oxygen-containing gas flow field extending along an electrode surface of a membrane electrode assembly, an oxygen-containing gas supply passage connected to the oxygen-containing gas flow field and extending through the first metal separator in a separator thickness direction, and a passage bead formed around the oxygen-containing gas supply passage and protruding in the separator thickness direction. A water drainage channel configured to connect an inner space of the passage bead with the oxygen-containing gas supply passage is provided at a lower portion of the passage bead.
