| 摘要 |
A fuel cell (10) according to the present invention includes a power generation unit (12). The power generation unit (12) is formed by stacking a first metal separator (14), a first membrane electrode assembly (16a), a second metal separator (18), a second membrane electrode assembly (16b), and a third metal separator (20). The number of flow grooves in a first oxygen-containing gas flow field (34) is different from the number of flow grooves in a second oxygen-containing gas flow field (48). The first oxygen-containing gas flow field (34) and the second oxygen-containing gas flow field (48) have the same length, and the flow grooves in the first oxygen-containing gas flow field (34) and the flow grooves in the second oxygen-containing gas flow field (48) have the same depth. |
